When a motor failure, it is generally necessary to check whether the motor is single -phase or the bearing damage, the unrequited axis of the coupling and the "wrapping" and other faults. During the operation, the entire motor made a "buzz" sound that was strong and weak. In addition, when the axis of the axis is unlimited or the motor is slightly sweeping, the entire motor will also make a very high "buzz" sound, which is accompanied by sharp and harsh sounds from time to time.

The decelerator fails (such as the gear box or the lack of lubrication, the bearing abnormal noise, the gear wear or damage, the bearing damage, etc.), then the check should be turned off. First, determine whether the gearbox or bearings of the deceleration must be used before the bearing. Oil is maintained regularly, because there is no lubrication, the deceleration will not only produce too much "buzz" sound, but also excessively wear or damage the gear and bearings. Secondly, the stop distance of the brakes exceeds the long -term application of the demand for electric gourds. The brake ring wear is too large, reducing the brake pressure of the spring and reducing the brake power. The solution adjusts the bolt or replace the brake brake ring. If the motor temperature is too high, check whether the gourd is overloaded first, resulting in electric heating. If the motor is not overloaded and the heat is still heated, the motor bearing should be damaged, and it should also be checked whether it meets the power requirements required by the work. This is also one of the reasons caused by electric heating. The motor is running, the brake gap is too small, there are quite large friction, which produces friction heat, and at the same time, it also generates additional loads, causing the speed of the motor to reduce and fever. At this timeElectric failure or reducer failure is the main factor that causes the electric gourd to make a "buzz" sound. If the electric gourd is found to make a "buzz" sound, it should be shut down in time, check the motor and reducer, and then take corresponding measures.
