Experimental Results of a locally developed BLDC Motor Controller for electric tricycle

The rapid growing battery-powered and plug-in hybrid electric vehicles will have a significant impact on power networks due to their zero carbon emission and mass deployment. DC motors, AC induction motors, and Brushless Direct Current (BLDC) motors are used worldwide in electric vehicles for years. Among them, BLDC motors are one of the electrical drives that are continually gaining popularity in motion control applications due to their high efficiency, good dynamic response and low maintenance. Unlike DC motors and Induction motors, BLDC motors need a controller as the motors run in 3 phase but take DC input. The controller converts DC power to 3 phase AC power suitable for the motor. This paper describes the design and development of a BLDC motor controller and its performance comparison with the existing BLDC motor controller imported from abroad. The controller circuit is simulated in Proteus software and the PCB is designed in ARES.
