Title:
DC MOTOR
Document Type and Number:
Japanese Patent JPS5992797
Kind Code:
A
Abstract:
PURPOSE:To reduce the inertial moment of a rotor by providing a flexible conductor of the length to be wound on a rotor in the set number upon rotating of a wound-rotor and controlling drive current by a rotating angle detection signal and an external control signal. CONSTITUTION:A rotor 14 is composed of a rotational shaft 12 and a winding 13, a permanent magnet 15 having a slit is secured inside a housing 10, and the winding 13 is rotated in the slit. A flexible conductor 16 having flexibility of marginal length to be wound on the shaft 12 is connected to the winding 12 when a rotor 14 rotates one revolution. An optical sensor 17 outputs an address signal in response to the rotating position of the rotor 14 to a memory 19 through signal lines A-C, a data signal based on the address signal is outputted from the memory 19, and the ON or OFF of the transistors 201-206 are controlled.
