Title:
DISC TYPE COMMUTATOR MOTOR WITH ROTATING SPEED DETECTING MECHANISM
Document Type and Number:
Japanese Patent JPS59220047
Kind Code:
A
Abstract:
PURPOSE:To enable to accurately detect a rotating speed of a disc type commutator motor with a simple structure by providing a pectinated conductive pattern for detecting the rotating speed at the stationary side position opposed to a pole for detecting the frequency. CONSTITUTION:An armature has groups of armature coils 7-1-7-3. N-and S- poles are magnetized at a fine equal interval pitch at the plastic magnet 12 of an outer periphery of the armature to form a pole 13 for detecting the frequency (rotating speed). A ribbon-shaped flexible substrate 15 is arranged fixedly on a body opposed to the pole 13. A pectinated conductive pattern 16 for detecting the rotating speed of a rotor is formed on the surface of the substrate 15.
