Getting started with the STEVAL-PTOOL2V1 compact reference design for
medium voltage brushless power tools based on STSPIN32F0252
Introduction
The
STEVAL-PTOOL2V1
is a ready-to-use reference design tailored for medium voltage power tools driven by 3-phase
brushless motors and supplied from 8S to 15S batteries. It can also effectively be used in other battery-operated applications
requiring similar architecture, rating and performance.
The
STEVAL-PTOOL2V1
is based on the
®
‑M0 STM32 MCU and
Cortex
The power stage can be populated with any power MOSFET with similar ratings and hosted in a powerFLAT 5x6 package.
The board has a single shunt sensing topology. Field-oriented control (FOC) and sensored or sensorless 6-step control
implementation allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.
This reference design can deliver up to 19 A of continuous current with very good thermal dissipation performance thanks to the
mounted heat-sink. It is compatible with a wide range (from 20 to 72 V
the
VIPER013BLS
in buck configuration to generate +12 V and +3.3 V supply voltage required by the application.
The
STEVAL-PTOOL2V1
embeds a potentiometer for speed variation and is fully protected from thermal shutdown,
undervoltage lockout and overcurrent.
It comes in a compact layout of 80 x 58 mm and includes the
position feedback from Hall effect sensors.
The
STSW-PTOOL2V1
firmware can be debugged and configured through an external
LINK/V3MINI).
