Motor drives and motor control

Nexperia

The Nexperia NEVB-MCTRL-100 BLDC motor driver kit provides a full motor drive solution for 12 V to 48 V, three-phase brushless dc (BLDC) motors. 

The kit features PCBs designed for the Nexperia NextPower MOSFET family housed in an LFPAK56 package, and the modular design allows for different motor controllers, gate drivers, MOSFETs and motors to be used. In addition, each board provides convenient test points for power, motor drive, and sensing signals to aid with development and testing with the Nexperia LFPAK56 MOSFET family. 

The motor controller board is compatible with the Leonardo R3 and Nucleo development board form factors.

The EVSPIN32G02Q1S1 board from STMicroelectronics is a complete three-phase inverter design based on the STSPIN32G0251 controller, which integrates a three‑phase 250 V gate driver and an Arm® Cortex®-M0+-based STM32 microcontroller.

The power stage features STD17NF25 MOSFETs from ST, but can be populated with any IGBT or power MOSFET in DPAK or powerFLAT 8×8 HV package.

The board has a single-shunt sensing topology, and allows the designer to implement either a field-oriented control or six‑step control algorithm in either sensored or sensorless mode. The board is compatible with permanent magnet synchronous motors (PMSMs) and brushless dc (BLDC) motors.

The evaluation board supports a wide input-voltage range, and includes a power supply stage with the ST VIPER06XS in flyback configuration.

The EVSPIN32G06Q1S3 board from STMicroelectronics is a complete three-phase inverter based on the STSPIN32G0601 controller, which integrates a three‑phase 600 V gate driver and an Arm® Cortex®-M0+-based STM32 microcontroller.

The power stage features STGD6M65DF2 IGBTs from ST, but can be populated with any IGBT or power MOSFET in a DPAK or powerFLAT 8×8 HV package.

The board has a three-shunt sensing topology, and supports a field-oriented control (FOC) algorithm, in either sensored or sensorless mode. This makes it especially suitable for driving permanent magnet synchronous motors (PMSMs).

 The evaluation board supports a wide input-voltage range, and includes a power supply stage with the ST VIPER06XS in flyback configuration.

The B-G431B-ESC1 Discovery kit is based on the STM32G431CB microcontroller, the L6387 driver and STL180N6F7 power MOSFETs, all from STMicroelectronics. The kit is composed of a main power board and a daughterboard with an embedded ST-LINK/V2-1 debugger. 

The kit implements an electronic speed controller (ESC) which drives a single three-phase brushless motor performing a sensorless field-oriented control (FOC) algorithm and six-step control with speed regulation. It also provides an active braking function algorithm. The sensorless FOC algorithm ensures long operating time and optimal dynamic performance.

The Discovery kit accepts command signals from an external unit for driving and monitoring, such as a flight control board for a drone. The kit is equipped with several communication bus interfaces: UART, CAN, and PWM channels. A potentiometer and a user button are available for user control. 

The daughterboard includes a 5 V battery eliminator circuit. The main board includes over-current, over-voltage and thermal protection. 

The form factor makes this kit suitable for small and very light radio-controlled vehicles such as first-person view racing drones, while the motor-current capability fits the power requirement of larger vehicles such as prosumer drones.

The EVLPWD5T60 from STMicroelectronics is a 3-phase power board which allows engineers to evaluate the features of the PWD5T60 integrated motor driver IC.

The board supports a three- or single-shunt current sensing topology. A strip connector provides an easy interface to a microcontroller motor-control board. In addition, a 34-pin ST morpho header can be used to connect the EVLPWD5T60 board to an STM32 Nucleo MCU board through the X-NUCLEO-IHM09M1 motor-control expansion board.

Key features of the board include: 

  • High-voltage rail up to 400 V dc, limited by on-board bulk capacitor
  • Peak output current up to 1.2 A 
  • Output power up to 120 W
  • Input-voltage range: 9 V to 20 V
  • Sensored or sensorless field-oriented control or 6-step algorithm
  • Hall-effect sensor connector
  • Smart shut-down over-current protection
  • Bus voltage sensing

The EVLPWD-FAN-PUMP evaluation board for the PWD5T60 motor driver power stage from STMicroelectronics supports flexible, ready-to-use control methods, and so helps to accelerate the development of reliable, compact and efficient fans and pumps. 

The EVLPWD-FAN-PUMP board features the PWD5T60 and an STM32G0 microcontroller based on an Arm® Cortex®-M0+ core, enabling field-oriented control (FOC) or six-step control of permanent magnet synchronous motors (PMSM) and brushless dc (BLDC) motors. The board offers a choice of single- or triple-shunt current sensing. Because the PWD5T60 is highly integrated, it has enabled STMicroelectronics to implement the board’s motor power stage in a small circular form factor, making it ideal for use in fans and pumps. It also includes a power-supply circuit which provides 12 V and 3.3 V supply voltages for the application, with a complete ac line filter at the input stage.

The EVLPWD-FAN-PUMP includes built-in bus-voltage detection to help to take advantage of the safety design of the PWD5T60, which provides over- and under-voltage lockout protection for each bootstrap circuit to prevent unsafe or inefficient operation. 

The PWD5T60 is also robust, and features shoot-through protection with interlock and preset default dead time, providing fail-safe protection against shoot-through currents. Additionally, the PWD5T60 withstands voltage drops below ground.

The board is ready to use and runs the FOC and 6-step control firmware included in the X-CUBE-MCSDK motor control software development kit, which is available free of charge from the ST website.
