STMicroelectronics STM32G431RBT6 | Demoboard Ptool3 STSYS_G471
Compact, configurable and customizable reference design for battery-operated brushless power tools based on STM32G431 and STDRIVE101
Overview
| Topology | Other Topology |
Description
The STDES-PTOOL3A reference design is a compact system designed to control a BLDC/PMSM motor in a handheld battery powered tool, delivering power up to 250W.It works on the standard set of inputs such as throttle to control the motor torque/speed.The board can be connected to a suitable 24V/250W BLDC or PMPM power tool motor. More peak power can be delivered with heatsink or with arrangement for circulating air to achieve better power dissipation.This reference design is ideal for high-performance motor control employed in power tools such as drill machines, grinder, disc cutters, circular saws, leaf blowers, handheld mowers.Small form factor and ample compute power make it suitable even for application such as drones, wheelchairs, home appliances and robotic platforms.The board comprises a high performance STM32G431RB MCU featuring integrated op amps and comparators especially optimized for motor control applications along with a triple half bridge gate driver controlling six low voltages high current MOSFETS.STM32 G4 series MCU also hosts the CORDIC a hardware accelerator designed to speed up the calculation of certain mathematical functions involving vectors and trigonometric functions.The accelerator is particularly useful in motor control applications.The MCU features multiple ADC peripherals thereby enabling simultaneous sampling of motor phase currents.The board has the capability to use both six-step and FOC algorithm available in ST's MCSDK FW library. This ensures high performance of six-step and field oriented control (FOC) of the motor.
