The term "servo motor" means that the motor is used with a feedback device (e. A stepper motor is a brushless electric motor that converts digital pulses into mechanical shaft rotation. As discussed earlier, in a BLDC motor, the torque remains constant for a speed range up to the rated speed. The BLDC motor rotates because the permanent magnet on the rotor attempts to align itself in the direction of the magnetic field generated by the electromagnets of the stator. Torque motors have been around since at least 1970, and like most servomotors of that era, they used motors with brushes. , auto industry, battery powered bikes, scooters, electric cars, forklifts, golf buggies, boats etc. Thus, Brushless DC motors also known as electronically commutated motors, where in torque ripples are minimized generally by using current control techniques but the present work has method of two level and four level torque controller for reduction of torque ripples in BLDC motor using the direct.
