High-Performance Interior Permanent Magnet Synchronous Motor for Electric Vehicles over Wide Speed Range

Battery electric vehicle (EVs) has become very popular with the interest of environmentally friendly electric vehicles rather than the conventional-Internal Combustion Engine (ICE) vehicles. To run with power, it needs the continuous wide working speed range of motors for the stable power region, strong power in high speed and a great start rallying torque in the low speed. This paper presents a simulation model of an Interior Permanent Magnet Synchronous Motor IPMSM for electric vehicle (EV) traction purpose in MATLAB/Simulink. This consists of Field Oriented Control (FOC), and runs Flux Weakening (FW) controller. 25 The EV market grows rapidly, hence the IPMSM is the best motor for such application due to that the motor has high torque-to -current ratio, high power mathematical eqns. We were able to identify behavior of the motor using FOC control also below base speed, when using FW control at rated speeds; the model indicated response was robust [1]. In addition, we will demonstrate greater high-speed torque using a feedforward flux weakening controller method, with constant power. The responses of speed, below and above rated speed will be stated regarding the results of the simulation. This model approach can suggest a rough level of advice on how to select an appropriate IPMSM configuration regarding distinct vehicle applications and drive conditions.
