STMicroelectronics STEVAL-PTOOL4A ARM Cortex Development Board STEVAL-PTOOL4A

The STMicroelectronics compact system designed to control a brushless DC (BLDC) or a permanent-magnet synchronous motor (PMSM) in application such as a handheld battery-powered tool. It works on the standard set of inputs such as throttle to control the motor torque/speed and to deliver power up to 250 W. This reference design is ideal for high-performance motor control to realize power tools such as drill machines, grinders, disc cutters, circular saws, leaf blowers, handheld mowers etc. The small form factor and ample computing power make it suitable even for applications such as drones, wheelchairs, home appliances, e-bicycles, and robotic platforms.

Supports peak power delivery with additional cooling options like heatsinks or air circulation for better dissipation
Supports both six step and high performance field oriented control (FOC) algorithms, with configurability options via the MCSDK library
Features integrated peripherals for motor control, including multiple ADC peripherals for simultaneous sampling of motor phase current and back EMF voltage
Input voltage from 12 to 28 V DC (Nominally 21 V)
Output RMS current up to 20A
