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
