Title:
ELECTRIC MOTOR CAR SYSTEM HAVING NORMALLY LEVITATING FUNCTION AND OBTAINING PROPELLING FORCE FROM MAGNETIC FORCE
Document Type and Number:
Japanese Patent JPH0199408
Kind Code:
A
Abstract:
PURPOSE:To reduce power consumption, by levitating or propelling a device by a magnetic force between a horse-shoe permanent magnets set continuously on a track, and permanent magnets and electromagnets arranged on an electric motor car. CONSTITUTION:On a track 2, horse-shoe permanent magnets 3 are continuously fixed and set in the same direction, and on the side wall, permanent magnets 7 are set. On a car body 1, the poles of the permanent magnets 3, 7 and the same poles of permanent magnets 4, 5 are arranged oppositely with each other. Besides, electromagnets 8 are set. Then, a device is levitated by a magnetic force between the permanent magnets, and the current of the electromagnet 8 is controlled, and a propelling force is controlled. As a result, the device can be run with low power.
