Abstract : Induction motors and BLDC (Brushless Direct Current) motors have revolutionized the market of Electric Vehicles. Both types of motors are used in the automobile industry. These motors are gaining popularity over others type of motors in a fast and progressive manner. BLDC motors are replacing induction motors in automobile and servo applications. It produces constant torque with trapezoidal back emf and rectangular stator current. Its advantages over others are reckonable and user-friendly. These are used on a power range up to few MW. Unlike four-wheeler EVs, two-wheeler EVs have limited space for energy sources. Hence, motor efficiency is a key factor in two-wheeler applications. In this paper, modeling of BLDC motors for different rotor configurations to be used in electric bikes has been carried out. Torque, speed, efficiency, and other parameters have been analysed based on the simulation result. Co-Simulation of ANSYS Model of most suitable rotor configuration is carried out with the drive system, and results are analysed.
