However, the stator structure with windings constructed to produce a sinusoidal flux density in the airgap of the machine resembles that of an induction motor. Permanent magnet synchronous motors' power density is higher than induction motors with the same ratings since there is no stator power dedicated to magnetic field production.

Motor constants

A permanent magnet motor would not produce energy and would not be a perpetual motion machine. Instead, it would simply use the electromagnetic energy delivered by the angular momentum of the electron in the form of magnetic forces.

History of perpetual motion machines

Brushless vs. brushed motors. Brushed DC motors were invented in the 19th century and are common. Brushless DC motors were made possible by the development of solid state electronics in the 1960s.. An electric motor develops torque by alternating the polarity of rotating magnets attached to the rotor, the rotating part of the machine…
