Motor drives and motor control

STMicroelectronics

The EVLSTGAP3SXS-H is a half-bridge evaluation board designed to evaluate the STGAP3SXS isolated single gate driver for SiC MOSFETs.

The STGAP3SXS offers 10A current capability, rail-to-rail outputs and optimized UVLO and desaturation protection thresholds for SiC MOSFETS. This makes the STGAP3SXS optimal for high-power motor drivers in industrial applications.

The gate driver has a single output pin and a driver line for an external Miller clamp N-channel MOSFET, which optimizes the suppression of positive and negative gate spikes during fast commutations in half-bridge topologies.

The board is supplied by the 5V VAUX connection, which feeds the isolated dc-dc converters for the low-side and high-side driving sections. The gate drivers can be directly supplied by VAUX if a 5V MCU is used, or by the onboard linear regulator if a 3.3V MCU is used. The PWM and Reset inputs can be easily controlled through dedicated connectors while diagnostic outputs are connected to an onboard LED.

Device protection features for desaturation, soft turn-off, and Miller clamp are connected to the recommended network on the board and can be easily evaluated through the board test points.

Dual input pins allow the selection of signal polarity control and implementation of HW interlocking protection to avoid cross-conduction in case of controller malfunction.

The STGAP3SXS allows the implementation of negative gate driving, and the onboard isolated dc-dc converters allow working with optimized driving voltage for SiC MOSFETs.

The EVLSTGAP3SXS-H board allows evaluating all of the STGAP3SXS features while operating with a bus voltage up to 520V. It is possible to increase the bus voltage up to 1200V by replacing the two SiC MOSFETs with appropriate devices in a HiP247-4 package and the C4 capacitance if needed.

STMicroelectronics

The EVLSPIN32G0A1 evaluation board from STMicroelectronics provides a hardware platform for assessing the STSPIN32G0A1 integrated motor-control system in three-phase brushless dc (BLDC) motor applications. 

The board operates from a supply range of 7V to 45V, and includes a power stage built from six STD140N6F7 MOSFETs which conduct up to 15Arms of continuous current. A three-shunt sensing topology is implemented to support high-performance field-oriented control and 6-step drive algorithms.

The board integrates voltage monitoring, PCB temperature sensing, an over-current comparator and under-voltage checks on driver supplies, enabling evaluation of the protection functions without external hardware. Digital Hall sensor and encoder inputs are provided for rotor position feedback, and bus voltage measurement is available for control loop implementation. 

The onboard regulators supply 3.3V and 12V rails for the integrated microcontroller and gate driver.

An embedded ST-LINK/V2-1 interface allows programming, debugging and UART communication through a Virtual COM port. User inputs include buttons and a potentiometer for speed and parameter adjustment during motor testing. When used with the STM32 Motor Control SDK, the board supports development and verification of control firmware for power tools, small appliances, fans, robotics and other low- to mid-power BLDC motor drives.

Monolithic Power Systems

The EVKT-MOTOR-00A from Monolithic Power Systems provides a communication link between a USB interface and a serial peripheral or I2C interface. It enables developers to connect a PC to motor drivers, such as the MP6602 stepper motor driver, that use a serial interface, as well as to an MPS motor driver programming tool.

The EVKT-MOTOR-00A kit includes one USB communication device interface, one USB cable, and one 10-pin ribbon cable.

Microchip

The ATA6847 evaluation board provides a fully assembled hardware platform for evaluating and demonstrating the motor drive capabilities of the ATA6847 gate driver system basis chip (SBC) from Microchip.

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.

STMicroelectronics

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.
