Title:
CONTROL AMOUNT LIMITER FOR MOTOR
Document Type and Number:
Japanese Patent JP3099023
Kind Code:
B2
Abstract:
PURPOSE: To simplify a control amount limiter for a motor to so control as not to operate the motor over a range of a predetermined rotating angle without providing a resistor, etc., for absorbing a counterelectromotive force of the motor which has been heretofore necessary.
CONSTITUTION: Switch means 41A, 41B are so composed as to be tuned OFF when a rotating angle of a motor 31 reaches a predetermined rotary angle. In such a circuit, when Tr2, Tr4 are tuned ON and the means 41B is, for example, turned OFF during energization of the motor 31, the motor 31 is short- circuited through a ground and a capacitor C4, and immediately stopped. If the Tr2, the Tr4 are turned OFF and Tr1, Tr3 are turned ON from this state, a current flowing to the motor flows to the ground side through the switch means which was turned OFF, and the motor is started to be reversely rotated.
