The motor is a critical component of the electric push rod, primarily responsible for providing a lateral electrical thrust to the push rod's shaft, which is then converted into a longitudinal thrust to propel the rod in reciprocating motion.

Below, we analyze the common types of motor failure conditions.

1: The motor's rotation is uneven. Theoretically, the speed of the motor's rotation should remain constant. If an uneven speed occurs, it is generally due to the driven object not being securely fastened by the electric actuator, resulting in constant摇晃. Additionally, check if the belt wheel is worn out, causing varying resistance during rotation.

The motor rotates slowly. This phenomenon first requires checking if the driving object is overloaded, as overload would definitely cause slow rotation. Another possibility is that the motor has been unused for a long time, leading to rust or insufficient lubrication, which can also result in this issue.

If the motor is not turning, first check if the object being propelled is overloading or if the path of movement is obstructed and cannot be moved. Then, inspect the power lines for any abnormalities. If the above issues are ruled out, check if the circuit breaker near the motor reset switch is closed. That should cover the basic scenarios.

The motor is rotating at an excessive speed beyond the theoretical limit. Check if the voltage is too high and also inspect whether the speed control protection device is functioning properly, as maintaining this condition for an extended period can easily damage the circuit board.
