Document Type and Number:
Japanese Patent JP3089321
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor which produces energy from powerful neodymium permanent magnets. SOLUTION: In an electromagnet formed by winding a coil on an entire electrical iron the length of which is three times the length of a neodymium permanent magnet rotor, straight lines of magnetic force are produced in the center of the electromagnet, equivalent to 1/3 of the electromagnet. (Refer to the drawing.) The lines of electromagnetic force during the period exert only in the direction of rotation. When the electrode of the electromagnet is changed by a commutator and the powerful neodymium permanent magnet is rotated during the period, large rotational force is produced. The motor is capable of moving the powerful neodymium permanent magnet on low-voltage and small current. Since the motor have a large gap (not more than 5 mm), nothing results without the powerful neodymium permanent magnet. If the motor is used for an electric vehicle, only a small quantity of electricity is required in the electric vehicle.
