Installation & Operation Guidelines

Important Safety Instructions

Compatible with 3-phase brushless DC motors with Hall sensors (120° angle)
Install heat sink when output power exceeds 60W
Apply insulation layer for 6pcs MOS and use heat-conducting silicone grease
Verify correct Hall sensor sequence to prevent damage
Use only within specified voltage range (12V-36V)
Do not connect external 5V power supply for speed control

Heat Sink Installation

Proper heat management is critical for reliable operation. When installing heat sink:

Add insulation layer for all 6 MOS components
Apply heat-conducting silicone grease for optimal thermal transfer
Failure to insulate may permanently damage the driver board
