  • Synchronous Motor

    Synchronous motors are inherently not able to self start on an AC power source with the utility frequency of 50 or 60 Hz As stated in Chapter 1 this is because synchronous motors can develop a torque only when running at the synchronous speed.However the synchronous speed for the utility frequency is too fast for the rotor to synchronize for starting as shown in Fig 3.63.
