Squirrel-cage rotor
Videos
A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminum or copper conductors cast in its surface. In opera

Synchronous motor

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. Synchronous motors use permanent mag
Squirrel-cage rotor
…The interaction between the stator's revolving magnetic field and the copper-pipe-rotor's induced magnetic field produces a torque and thus rotation. A synchronous motor may have a squirrel-cage winding embedded in its rotor, used to increase the motor starting torque and so decrease the time to accelerate to synchronous…
Miniature synchronous motor used in analog clocks. The rotor is made of a permanent magnet.
