In a synchronous motor the torque angle is
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 … See more A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of See more A permanent magnet synchronous motor and reluctance motor requires a control system for operating (VFD or servo drive). There is a large … See more The operation of a synchronous motor is due to the interaction of the magnetic fields of the stator and the rotor.
