A permanent magnet motor which generates mechanical output power by the repulsion forces between a movable permanent magnet and a fixed permanent magnet A movable magnetic shield is interposed between the magnets when they are adjacent one another and then the shield is moved to expose the fixed magnet as the movable magnet passes by A second fixed magnet can be added to increase

Permanent Magnet Synchronous Machine

The Simulink input is the mechanical torque at the machine shaft This input is normally positive because the Permanent Magnet Synchronous Machine block is usually used as a motor If you choose to use the block in generator mode you can apply a negative torque input w

permanent magnet DC motor's design uses these forces to create a torque on the motor's rotor which is constrained by the motor's bearings so that the only motion permitted is rotation (see Figure 19 1 and Figure 19 2) Permanent magnet DC motors are constructed out of a

Magnet Motor John Dodd: The Techno Maestro's Amazing Machine (Japan by the time he'd won patents in 47 Pumping action by the hand held magnet is not the power that drives the motor When the drive magnet is moved away from the wheel it coasts rather quickly to a stop and comes to rest in a manner typical of any spinning

This cannot start the motor so the rotor poles usually have squirrel-cage windings embedded in them to provide torque below synchronous speed The machine starts as an induction motor until it approaches synchronous speed when the rotor pulls in and locks to the rotating stator field
