Title:
DC MOTOR FOR CONVERTING MAGNETIC ENERGY INTO MECHANICAL ENERGY
Document Type and Number:
Japanese Patent JPH04117160
Kind Code:
A
Abstract:

PURPOSE: To obtain a DC motor, power of which does not decrease even under high speed rotation, by employing a structure producing no counter-electromotive force and using electric energy only for magnetization of the core of an electromagnet thereby producing a rotary motion energy higher than the electric energy to be consumed.

CONSTITUTION: A soft magnetic rotor 5 provided with six teeth with same intervals is fixed to a rotary shaft 6. A stator 2 provided with six electromagnets with same intervals is similarly fixed to an outer frame 1. Opposed electromagnets of the rotor 5 and the stator 2 are arranged to have identical magnetic force and flux density at all times. When a current is fed, attraction force functions between the poles of the stator 2 and the rotor 5 which thereby begins to rotate forward. Since the intensity of magnetic field of opposing electromagnets of the rotor and stator is identical at all times, flux density does not change even if the fields overlay thus producing no counter-electromotive force in the coils of both electromagnets. Consequently, the force does not decrease and a rotary motion energy higher than the electric energy to be consumed can be produced.
