Why Does the Electric Motor Overheat?

Electric motors are widely used in the workplace and at home. The new engine, passed factory tests can regularly work a few years. But in violation of the rules of operation sometimes there are faults. One of them is the overheating of the engine, which may well lead to a complete damage it.

Why the Electric Motor Overheats

Disturbances in the motor (e.g. the 300 RPM motor) can be caused by several reasons. These often include a violation of the rules of transportation, storage and installation, and the use of unacceptable operating conditions. Sudden shocks, prolonged vibration and shock is likely to disrupt the integrity of the elements of the engine and it can lead to overheating when working. Even worse, if the motor is stored for a long time in the open air, it feels the effects of low temperatures and high humidity. These adverse factors may well cause the appearance on the outer surface of the rotor and the stator core of rust.

One of the most common faults of the motor is damaged insulation of coils, which in most cases leads to a local short circuit. During operation, the unit begins to warm up strongly, the rotor rotates unevenly, and the machine shaft is permanently deformed. Winding insulation can damage the engine careless transportation, and foreign particles from entering the body. BTW, you can select the cheap gear motor and RPM measurement tool at Banggood.

Other Causes and Possible Remedies

If the engine is turned rotor scrolls with difficulty or not at all is fixed, and at the same time there is intense heating of the body, it is possible degradation of the bearing. With such a rotor and stator faults hit against each other, it leads to a complete jamming. Typically in such a case is required to send an electric motor repair replacement bearing. Overheated motor often occurs when it is overloaded, for example due to high or low voltage. The sharp increase in the room temperature, clogging ventilation channels can also lead to such an effect.

In continuous and prolonged operation of the engine, you can often observe a reduction in power. The electric machine is working at the limit mode, but cannot gain the necessary speed, at the same time starting to heat up. The reason again is becoming overloaded, you want to eliminate. In some cases it is sufficient to switch off the unit and leave it for a while in this state.
