Description
Features:
- For high voltage DC motors (100v, 220v) with power from AC.
- ~ 500W without heatsinks, up to 1500W with heatsinks.
- Sensorless RPM stabilization (measure RMP via back EMF).
Simplified schematics (small size, few details):
- no isolation (!!!)
- use resistor with plastic shaft
- attach to usb/stlink only when power off
