MOTOR USING PERMANENT MAGNET

摘要

PURPOSE: A motor using a permanent magnet is provided to increase the output efficiency of the motor by adding the magnetic force of the permanent magnet to the magnetic force of an electromagnet and transmitting the added magnetic force to a rotor. CONSTITUTION: A rotor(20) comprises a permanent magnet(21) or an electromagnet(33) and a rotary shaft(22) which is combined with the center of the permanent or electromagnet and transmits a rotation force. A stator(30) comprises the electromagnet which is magnetized when a current is applied and the permanent for rotating the rotor when the electromagnet is magnetized.
