WORKING AND CONSTRUCTION OF BLDC MOTOR

  ABSTRACT Electric vehicles are the best solution for green transportation due to their high efficiency and zero greenhouse gas emissions. Various electric motors have been used as the propulsion system of electric vehicles. Performance of brushed Direct Current (DC) motors, induction motors, switched reluctance motors, and permanent magnet Brushless DC (BLDC) motors are compared according to the in-wheel motor technology requirements under normal and critical conditions through simulation. This study shows that BLDC motors are the most suitable electric motor for the high-performance electric vehicles. An accurate model of a BLDC motor is needed to investigate the motor performance for different control algorithms. Therefore a BLDC motor with an ideal back-Electro Motive Force (EMF) voltage and its control drive are modelled in Simulink. Correct performance of the BLDC motor drive model is validated through experimental data. Direct torque control technique is a type of flux ...
