Description

TECHNICAL FIELD

[0001] The utility model relates to motor field, specifically, a kind of positive and negative rotation motor control detection circuit. BACKGROUND

[0002] Many mechanical equipment in industrial field are installed with positive and negative rotation motor, such as material conveyor belt, robot joint arm, mixer and so on. The power connection mode of positive and negative rotation motor installed on these mechanical equipment can not distinguish positive and negative. Through the control signal of control equipment, the positive and negative rotation motor can be switched between positive rotation and reverse rotation in use, so that different functions are used. But when positive and negative rotation motor is used, it may be stuck in positive rotation working process or reverse rotation working process, or positive and negative rotation motor appears running overload in working, causing positive and negative rotation motor to be burned. Since positive and negative rotation motor does not distinguish positive and negative of power supply when connecting power supply, setting detection circuit at the end of positive and negative rotation motor connected with power supply positive pole and the end of positive and negative rotation motor connected with power supply negative pole will cause cost increase and circuit volume increase.
