There are many configurations of ac synchronous motors in which semiconductor control is used for controlling the stator currents in such a way that maximum torque is obtained at a given speed. Such configurations can be termed as brushless dc motors (or BLDC motors). Fig. 1: Construction of BLDC motor.
