Abstract
PURPOSE: To dicide wether it is the abnormality at load side or at controller side through logic circuit, when the speed or the torque of motor varies, by deciding wether these varying polarities are same with varying polarity of motor current.
CONSTITUTION: The speed of DC motor 10 is controlled by the power supplied from thyristor controlled power source 11. When the motor speed varies abruptly due to the abnormality at load side, current in differential amplifier 19 increases to produce positive output signal while the amplifier 20 produces nigative output signal, and AND gate 22 functions to produce a signal on terminal b. When a abnormality occurs at controller side both output signals from amplifiers 19, 20 become positive, and AND gate 21 functions to produce output signal on terminal a
