Specifications

This controller was designed to drive the Anaheim Automation BLY 342S-48V-3200. A 48V, 8-pole, 3-phase BLDC motor with Hall sensor feedback:
-48V maximum
-4.5A Continuous, 9A Peak currents
-0RPM to 3200RPM
-Closed loop PI motor speed control
-Motor direction selection
-Real-time rotor position control

The driver meets all of these specs, although the rotor position control is not ideal, it still proves the concept.
