This paper designs and implements a 22 kW class brushless DC (BLDC) motor driving system test bed for hybrid electric vehicle (HEV) applications. First, the specifications and the driving system architecture of the BLDC motor are introduced. Then, a 22 kW BLDC motor driving system with an analog open-loop and closed-loop speed control system is described. Accordingly, a hardware prototype is built. Finally, experimental results verify the functions of the 22 kW BLDC motor driving system test bed.
