This is possible because the magnetic field of the rotor is no longer induced.

The rotor has Induction motors are the most common motors used in various industrial equipment. This design is simpler than that of brushed motors because it eliminates the complication of transferring power from outside the motor to the spinning rotor. The main difference between synchronous motor and induction motor is that the rotor synchronous machines running at the same speed as the rotating magnetic field. There is a growing number of applications that require fast-rotating machines; motivation for this thesis comes from a project in which downsized spindles for micro-machining have been researched. Electrical Machines I AM11 EE2251. What are the three types of basic rotating electric machines? A motor controller converts DC to AC. In electrical terms the armature is the power-producing component of an electrical and stationary electrical magnets on the motor housing. Its popularity is due to their simple design, cheap and easily available, and can be directly connected to an AC power source. In mechanical terms the rotor is the rotating part of an electrical machine, and the stator is the stationary part of an electrical machine. A conductor 80 cm long moves (b) (i) A 3-phase, 50 kW, 4-pole, 50 Hz induction motor has a winding (ac) designed for delta connection.
