The main reason for the breakdown of the electric motor insulation is that the surge voltage generated by the resonance of the capacitors and inductors distributed on the output line is superimposed on the output voltage, or the high switching frequency and lo...

Due to operational problems, many users may encounter various problems in the process of using DC motors. Among these, the phenomenon of burning out is relatively rare, but once the machine occurs, it will be scrapped, which seriously affects our use. The l...

How is the axial force of a three-phase asynchronous motor generated? Whether it is a high-voltage or low-voltage electric motor, shaft displacement problems or axial force causing bearing temperature to rise are reported from time to time. The best operating ...

Analysis of the causes of three-phase asynchronous induction AC motor burnout, the causes of three-phase AC motor burnout can be divided into load, power supply, motor insulation, and phase loss. Three-phase AC motor load (overload) burnout: The motor heats...

In the field of industrial production and power drive, three phase asynchronous electric motors are core equipment components, and their reliability is crucial. One of the key indicators for measuring motor reliability is the mean time between failures (MTBF)....

The insulation resistance of a motor is a key parameter for evaluating its insulation performance, which is directly related to the safe operation of the motor. Due to the different types and voltage levels of motors, the minimum standards for insulation resis...

To ensure the continued integrity and safety of explosion-proof AC motors, a rigorous post-repair inspection is paramount. This inspection is designed to verify adherence to explosion-proof standards and identify potential issues that could compromise the mo...

The variable frequency motor is the main power source of various mechanical devices. In order to ensure the continuous and reliable operation of the device, the daily maintenance and regular maintenance of the variable frequency motor are very important. Th...

The protection level system standard was drafted by the International Organization for Standardization IEC, which classifies electrical appliances(three phase electric motor) according to their dust and moisture resistance characteristics. The IP protection le...

The causes of three-phase AC motor burnout can be divided into load, power supply, motor insulation, and phase loss. Three-phase AC motor load (overload) burnout: Under overload operation, the motor heats up. Or the motor starts frequently and the motor ove...
