STEVAL-PTOOL2V1 Motor Control Reference Design for Power Tools
Author: EIS Release Date: Jan 12, 2021
STMicroelectronics' reference design for power tools supplied by 8S to 15S batteries comes with a full set of active protection features
STMicroelectronics' compact 3-phase brushless motor control reference design is ideal for power tools supplied by 8S to 15S batteries. It features the STSPIN32F0252 motor controller with embedded 3-phase 250 V gate driver and Cortex® M0 STM32 MCU.
The board implements a single shunt sensing topology and supports FOC and 6-step control techniques to drive either PMSM or BLDC motors. It can deliver up to 19 A of continuous current from a wide input voltage range of 20 VDC to 72 VDC and includes an auxiliary power supply stage with the VIPER013 high-voltage converter. The setup includes a potentiometer for speed variation, and it comes complete with a full set of active protection features.
