Abstract: This study describe the mathematical method applied for realizing optimized electromagnetic torque with reduced ripple in a two phase brushless dc motor with special rotor construction. The conventional construction of two-phase two-pulse brushless dc motor is inapplicable due to high torque ripples, Low mean torque and speed fluctuation, therefore a special rotor construction with aim to realize successful starting and ensuring relatively constant torque with minimized ripples and independent of the rotor position is going to be applied. In addition to introducing the modified rotor construction, a combined PWM control strategy and continuous control signal energized two-phase three-windings motor is applied. The produced electromagnetic torque by this approach is determined by applying Coenergy method and the numerically obtained results are going to be verified with experimental results. Good coincidence between both results is expected to be achieved.
