Industrial BLDC Motor Drive Interface Module

The BLDC control solution is an industrial grade device which uses NXP’s Motor Control Unit, and is designed for low to high voltage operation. The solution provides control over motor rotation speed, forward,reverse rotation and failure detection like commutation error, over current and over voltage.Rotor position estimation is done using Hall sensor technique.

The motor speed is controlled using rotor position feedback fed to the speed regulator done by three phase power stage PWM.The solution shall be controlled using RS-485 interface by the user.
