[0002] For a barrier gate servo core, the servo core converts electrical energy into mechanical energy through a DC brushless servo motor to provide power for the lifting of the barrier gate. The rotor of the motor rotates under the action of the magnetic field generated by the stator, drives the barrier rod to rise or fall through a transmission mechanism, and precisely regulates the operation of the motor by using control methods such as position servo, speed servo, and torque servo.
