What causes the motor heating failure of hydraulic press

The motor plays a very important role in the hydraulic press system. Why does the motor of the hydraulic press heat up and fail? What is the cause, today we will understand the hydraulic press motor heating intentionally

First, the motor overload analysis, use the clamp meter to measure the normal electrical flow of the motor, if the electrical flow of the load operation of the motor appears large and small, it may be the hydraulic pressure is increased; If the current is relatively large when it is just started, and the current of the hydraulic system is too high when it does not start running, it means that the motor has a problem.

Second, check whether the bearing of the motor of the hydraulic system is stuck and the rotor is swept, because when there is such a failure, under normal circumstances, the operating technician can hear the sound.

Third, the voltage fluctuation of the external power grid becomes larger, and it is immediately clear when the multimeter is used to detect it. Perhaps the hydraulic pump resistance is large and the motor does not match the pump and the motor insulation drops and is installed after disassembly for moderate reasons.
