The switch circuit is configured to access a control voltage; and the discharge circuit is connected to the switch circuit and configured to be connected to a driving positive electrode and a driving negative electrode of the galvanometer motor.
Claims10
A control circuit of a galvanometer motor, configured to control the galvanometer motor to be discharged during a power failure, wherein the control circuit comprises:
- a switch circuit, configured to access a control voltage;
- and
- a discharge circuit, connected to the switch circuit and configured to be connected to a driving positive electrode and a driving negative electrode of the galvanometer motor,
- wherein during the power failure, the switch circuit controls the discharge circuit to be short-circuited based on the control voltage, to release a reverse induction electromotive force between the driving positive electrode and the driving negative electrode of the galvanometer motor that is generated due to the power failure.
LiDAR, comprising:
- a galvanometer, configured to change an outgoing direction of a laser beam;
- a galvanometer motor, drivingly connected to the galvanometer and having a driving positive electrode and a driving negative electrode;
- and
- a control circuit of the galvanometer motor, comprising:
- a switch circuit, configured to access a control voltage;
- and
- a discharge circuit, connected to the switch circuit and configured to be connected to the driving positive electrode and the driving negative electrode of the galvanometer motor,
- wherein during a power failure, the switch circuit controls the discharge circuit to be short-circuited based on the control voltage, to release a reverse induction electromotive force between the driving positive electrode and the driving negative electrode of the galvanometer motor that is generated due to the power failure.
