Title:
SIGNAL GENERATOR
Document Type and Number:
Japanese Patent JPS58218859
Kind Code:
A
Abstract:
PURPOSE:To obtain the signal of a large output by arranging a large number of coils connected in the direction that induced voltage is added while being opposed to each magnetic pole of a revolution body magnetized so that the direction of a magnetic field alternately changes periodically. CONSTITUTION:The coils 14 are each arranged where opposite to each magnetic pole of a rotor 11 in which a large number of the magnetic poles 12 are magnetized so that the directions of N poles and S poles alternately replace periodically, each coil 14 is connected in the direction that induced voltage generated in several coil 14 is added, and the output signal is obtained. Accordingly, the large output signal is obtained because a change of the magnetic field can be detected directly.
