Abstract
A breaking circuit applied to a motor comprises an actuator, an anti-reverse component and a limiting resistor. The actuator comprises a first electricity transmission terminal, a second electricity transmission terminal and a controlled terminal, with the controlled terminal configured to be connected with a power supply port, and the first electricity transmission terminal configured to be electrically connected with a power input terminal of the motor. The anti-reverse component is electrically connected between the controlled terminal and the first electricity transmission terminal of the actuator. The limiting resistor is electrically and serially connected with the first electricity transmission terminal or the second electricity transmission terminal of the actuator. When power supplied from the power supply port to the power input terminal is stopped, the actuator is conducted to form a discharge path from the power input terminal through the limiting resistor to a low electric potential end.
