The permanent magnet synchronous motors are AC synchronous motor whose field excitation is provided by permanent magnets and that has a sinusoidal back EMF waveform. The stator magnets will have at least two permanent magnet poles. Artwork: A simplified diagram of the parts in an electric motor. View Answer NCERT Question 12 - Name some devices in which electric motors are used. 160W Brushless Permanent Magnet Motor 48v dc. The rotor locks in when the speed is near synchronous speed.
