Learn how you can leverage Future Electronics’ System Design Center

Brushed DC motors have been the predominate choice in power tool design, such as drills, for decades. However, adoption of Brushless DC (BLDC) in power tools is rapidly proliferating due to better efficiency and the availability of cost-effective BLDC motors. Today, in fact, most high-end power drilling tools use BLDC motors. The typical current rating of a power tool is much higher compared to popular consumer BLDC applications, such as drones and toys. Power drills must be capable of handling various kinds of material during operation, for example, when drilling a hole in a typical household wall, the drill bit first meets the relatively soft drywall, then the much harder wooden stud.

While it’s true that a dedicated current sensing IC can provide flawless motor phase current feedback, this is not a cost-effective solution for power tools. A power tool BLDC motor control block diagram is shown in the figure below.

This means that the load torque can vary considerably during operation. A Hall sensor is thus needed to provide the rotor position in real-time. Considering the high current rating, a discrete topology with external MOSFETs is typically used. Since motor current is very high, a small shunt resistor (about 1-5mΩ) is used for current sensing. Although the noise level is quite high when such a small resistor is used, layout and other techniques are necessary to find right the compromise between power dissipation and optimum measurement.

Advanced PWM peripherals targeting motor control applications 6 Quadrature Encoder Interfaces for multi-axis sensored feedback

Sensorless Single Motor Drive with PIC32MK By utilizing the internal OpAmps of the PIC32MK we reduce the need for external devices. Additionally, with the multiple ADC conversion cores of this series, we can dedicate an ADC per motor phase that we want to measure, rather than sharing the conversion of 2 or more phases on a single ADC. This reduces code complexity and offers increased resolution, as we are capturing more samples per phase without having to calculate complex timing between phases on a single ADC. Internal high speed comparators with PWM fault triggering are also used as overcurrent protection across the two measured phases.

SAM C Cortex®-M0+ Based Microcontroller (MCU) Series Builds on Decades of Innovation and Experience in Embedded Flash Microcontroller Technology It not only sets a new benchmark for flexibility and ease-of-use but also combines the performance and energy efficiency of an ARM Cortex-M0+ based MCU with an optimized architecture and peripheral set. SMART SAM C devices are truly differentiated 5V microcontrollers that are ideal for home appliances, industrial control and other 5V applications. CAN-FD, LIN and automotive qualification up to Grade 1 make the SAM C2x series a wise choice for automotive applications such as interior seats, door locks, power windows and more. Microchip’s SAM C2x Cortex M0+ line of microcontrollers balances single and dual motor control applications with a single, low cost, 5V MCU. Because these devices can run directly from 5V, they are the perfect MCU match for Microchip’s MCP8025 and MCP8026 BLDC gate drivers. These drivers feature an integrated 5Vout LDO AND integrated OpAmps and support up to 28V rails, making them perfect for portable battery-powered motor applications such as tools, vacuums, small robotics and toys that utilize multiple LiPO batteries.

For Hardware Development, Prototyping and Debugging The PIC32MK GP Development Kit (DM320106) offers a low cost solution for developers looking to build projects with the PIC32MK series of devices. Customers looking to develop motor control applications should also consider PIC32MK 1024 Motor Control Plug-in Module (MA320024).

The SAM C2x series is supported with an Xplained Pro kit (ATSAMC21-XPRO) that supports Arduino style add-on boards. For BLDC motor control applications, Microchip offers a 24V development platform – ATSAMD21BLDC24V-STK – featuring a complete power stage, motor, and swappable plug-in modules that support the C21, D21 and other devices. Customers looking to develop motor control applications with the C2x series on the BLDC24V-STK kit must purchase the ATSAMC21MOTOR card.

Dual sample and hold ADCs make easy work of complex timing requirement for reconstructing Back EMF signals, and high speed comparators ensure cycle-by-cycle overcurrent limiting for increased application safety and robustness. Additionally, a Sigma-Delta type ADC is also available in the C2x family, which can be used for V/I tracking, high accuracy temperature sensing and general metrology functions. A simplified application block diagram is shown below, representing the major connections from the SAM C2x to the power stage. As mentioned above, if used with an MPC802x series device, 5V for the MCU can be generated right from the driver chip, and both differential amplifiers are integrated into the driver for the Back EMF feedback loop.

Data Center FPGAs have contributed significantly to cloud computing, mobile computing, networking speeds and memory. Improvement in ESR and capacitance capabilities of Panasonic polymers have allowed FPGAs to play a part in these advances. FPGAs have allowed multiple “Industrial” sectors to become more efficient. Key examples are improvements in motor control systems, programmable logic controllers (PLCs) and safety equipment.

High Performance Computing Improvements in FPGA technology has enabled faster Software Writing to Hardware components and significantly faster processing times.

Automotive Changes over time in FPGA technology have optimized automotive production systems and contributed to decreasing production lead times. Other technologies such as adaptive cruise control and collision detection have also been in part due to FPGAs

For this reason, Triad Magnetics has developed the PC Mount Split Pack -C2 Series Transformers. They feature a split pack bobbin design, Class F 155°C insulation and global TUV approval. Unique Bobbin Design The -C2 Models F and FS PC Mount Split Pack Transformers are non-concentrically wound. Both the primary windings and secondary windings are side-by-side.

Higher Safety Ratings

Triad’s -C2 transformers feature greater creepage and clearance for better isolation. Improvements in its construction provide spacing between the primary and secondary windings of more than 10mm, preventing arcing to enhance safety and reliability. Dielectric Strength The -C2 transformer’s high potential, or hipot, testing for primary-to-secondary dielectric strength is 4200 VAC versus the standard 2500 VAC. The secondary-to-secondary hipot is 2150 VAC, providing sufficient isolation for independent use of the secondaries.

Unlike standard secondary-on-top-of-primary designs, Triad’s split bobbin and low capacitive coupling eliminates costly electrostatic shielding. This offers a dual, independent secondary configuration that can be connected in series or parallel for output voltage flexibility. 1

How ST’s Motor Profiler Tool Helps Accelerate Motor-Control System Design By: Gianluigi Forte, Andrea Spampinato, Marcello Palano, Alessandro Corsaro

Field Oriented Commutation (FOC), also called vector control, a method for controlling electric motors, was invented in the early 1970s, and remains the most advanced motor-control technique available to the system designer today. It operates by controlling the alternating currents that flow into the phases of the motor’s stator, decoupling them into two orthogonal components which rotate in a reference frame synchronous with the rotor’s magnetic flux – the so-called direct or ‘d’ and quadrature ‘q’ axes. In this way, it is possible to independently control both the torque and the magnetic flux, improving the motor’s efficiency and its dynamic response. By properly controlling these two currents, the system can produce the maximum torque for any given input current. It accomplishes two other goals: • To achieve the maximum efficiency • To produce a fast response to speed-control signals, resulting for instance in rapid settling at a new target speed, or robust control of speed after a large change to the applied load Other advantageous characteristics of FOC include the ability to produce controlled negative torque (enabling active braking), and to weaken the rotor’s magnetic flux (enabling operation at speeds above the nominal value). STMicroelectronics provides a rich set of resources to help design engineers to implement new motor-control system designs. These include the STM32 FOC Software Development Kit (SDK) for Permanent Magnet Synchronous Motors (PMSM). At the start of any design, however, the first task will often be to get a real motor spinning. This Technical View describes an ST tool, the Motor Profiler, with a PC-based GUI which makes it easy to configure a motor which is controlled by FOC (see Figure 1).

that, to drive it correctly, it is necessary to provide an energizing force field that is synchronous with the rotor flux. Problems arise when there is no sensor in the system for directly measuring the speed of rotation and the orientation of the rotor flux. When an incorrect force field is applied, the motor simply vibrates at the applied frequency but does not rotate. With the FOC technique, a robust rotor flux monitor or estimator algorithms are required in order to implement a drive circuit able to spin the motor at a controlled speed. The catch is that both FOC and the self-sensing technique are based on models of the motor and the inverter. And these models need to be populated with correct values for various parameters, both electrical and mechanical. Moreover, a number of regulators are present in the algorithms and these regulators need to be properly tuned. To tune these regulators manually would require repetitive empirical testing, after setting up firmware with the many parameters necessary for configuration. This approach is complex, and difficult to perform for engineers with little experience in motor control. To ease the process, ST provides the Motor Profiler, an automatic measurement system embedded in the motor-control algorithm. It estimates all the parameters required by the FOC algorithm, and performs auto-tuning of all the regulator parameters. The Motor Profiler allows any user to start a motor in a few seconds. The tool works with various combinations of ST’s control and power boards, so that an engineer can estimate the parameters of their choice of motor with its specific voltage and current requirements. At the end of the procedure, the tool shows the estimated values, and the system is ready to run the motor. How to use the Motor Profiler A Motor Profiler project starts with the choice of evaluation board. ST supplies many boards which are compatible both with the tool and with FOC. One of the most popular is the P-NUCLEO-IHM001 Motor Control Nucleo Pack (see Figure 2). This consists of: • A NUCLEO-F302R8 control board, which features an STM32F302R8 microcontroller based on an Arm® Cortex®-M4 core. Operating at 72MHz and providing 64kbytes of Flash memory and 16kbytes of SRAM, this device is intended specifically for use in FOC motor-control applications.

Why a Configuration Tool is Needed Engineers who have never worked with three-phase permanent-magnet motors might think that starting up a motor is like pushing a button. Not so. Three-phase motors are synchronous machines, so the position and the speed of the magnetic flux and the rotor are the same. This means

• An X-NUCLEO-IHM07M1 power board, connected to the control board via an ST Morpho extension. It is a three-phase driver board for brushless DC or PMSM motors based on the L6230 three-phase motor driver IC. It has a nominal supply-voltage range of 8V-48V and provides up to 2.8A of peak output current, or 1.4Arms. The board includes threeshunt and one-shunt current-sensing networks configurable by jumpers.

The STM32 PMSM FOC SDK may be downloaded directly from the ST website. Users should install it before running the Motor Profiler tool. The tool works with various ST boards: the user can select the P-NUCLEO kit from the list included in the tool. Next, set the only mandatory parameter: the number of pole pairs – seven if using the reference motor. Then choose the maximum value for current and voltage to be applied to the motor.

After clicking the Connect button, the Motor Profiler will establish a serial communication with the board. On first use, the board will be automatically programmed with the correct Motor Profiler firmware. Operation of the Tool The Motor Profiler firmware is able to perform a set of measurements using the inverter and the motor themselves as measurement instruments. No extra hardware or instrumentation are required. The inverter board’s current-sensing network will measure the current flowing into the motor phases and the PWM outputs which energize the motor terminals. These characteristics are sufficient to perform all the procedures required by the Motor Profiler.

Refining the Motor’s Operation At the end of the Motor Profiler procedure, the motor will be stopped. If the procedure has been successful, the system will be tuned for the motor. The user can then click on the Play button and start the motor spinning again, but this time in a tuned and controlled way. The Motor Profiler includes a slider which lets the user set a target speed, and a bar which represents the motor’s actual speed. By moving the slider, the user can verify that the motor is running at the target speed. It is also possible to set a negative speed, reversing the direction of rotation from clockwise to counter-clockwise. If a fault condition occurs, it is indicated by a set of LED indicators in the GUI. For instance, if the power supply to the inverter is switched off while maintaining the supply to the microcontroller board, the Bus UnderVoltage LED will turn red, indicating a fault condition, and the motor will stop. As soon as the fault condition ends, the motor will restart automatically at the most recently set speed. By using the Motor Profiler tool, all of the configuration and control of a real-world motor has been accomplished without writing a single line of code, or even installing a compiler or any kind of development environment.

The simplest measurement taken by the Motor Profiler is the phase-tophase resistance: to do this, a voltage is applied to the motor terminals, and the current is measured by the current-sensing network. The resistance is computed by applying Ohm’s law. From this point, the Motor Profiler’s operation uses an incremental approach: when a measurement has been performed, the value is used to perform the next measurement. For instance, once the stator phase’s resistance has been measured, the value is used to measure the stator phase’s inductance. The incremental measurements and computed values are shown in the GUI. After the electrical measurements, it is the time for the mechanical parts. The motor is sped up by increasing the torque in steps in order to measure inertia and friction. The Motor Profiler provides the best results if the tests are performed in the same conditions as the final application. The Motor Profiler procedure should therefore be performed when imposing on the motor a torque or load that is equivalent to the load that the motor will drive in the final application.

The engineer can save the results of the configuration in a motor database, and use them in the ST Motor Control Workbench in the ST PMSM FOC SDK, a fully customizable environment for developing motor applications.


Alongside the boards, pack includes a reference motor: a seven pole-pair motor which has a nominal voltage of 11.1V DC and a maximum DC current of 5A.
