WebMay 9, 2014 · Split Phase Induction Motor. The single-phase induction motor has distributed stator winding and a squirrel-cage rotor. When fed from a single-phase supply, its stator winding produces a flux ( or field ) … WebThe synchronous motor is not inherently self-starting because_____? A. the force required to accelerate the rotor to the synchronous speed in an instant is absent B. the starting …
Above a certain size, synchronous motors are not self-starting motors. This property is due to the inertia of the rotor; it cannot instantly follow the rotation of the magnetic field of the stator. Since a synchronous motor produces no inherent average torque at standstill, it cannot accelerate to synchronous speed without some supplemental mechanism. Large motors operating on commercial power frequency include a squirrel-cage induction windin… WebThis will tend to rotate rotor in the direction of rotating magnetic field. But before this happen, stator poles again change their position reversing the direction of the torque …
