Why does an electric motor burn up when you physically stop it? As an electric motor spins, the energy from the electricity is 'conducted' to the rotor by the magnetic fields. However, when the motor is stopped, the energy becomes heat and burns up to motor.
When electric motor fails – you can do few things, but before motor fails – you can do many many things to suppress eventual failure or heavy damage. Winding insulation breakdown and bearing wear are the two most common causes of motor failure, but those conditions arise for many different reasons.
As an electric motor spins, the energy from the electricity is 'conducted' to the rotor by the magnetic fields. However, when the motor is stopped, the energy becomes heat and burns up to motor. What causes this heat to be formed?
Most of them are caused by the over-heating of motor. There are also other factors which greatly affect the performance of electric motors such as low resistance, dirt, moisture, over-current and vibrations. Electric motors should be installed very carefully and should be looked after at regular intervals.
If your electric motors overheat for any reason, it can create numerous performance issues, including electric motor failure. Overheating can occur when electric motors attempt to run in high-heat environments, which can reduce the heat conduction rate, damaging your electric motor significantly.
Vibration: There are a number of possible causes of vibration, such as misalignment of the motor. Corrosion of parts can also cause the motor to vibrate. The alignment of the motor should be checked to eliminate this issue. Most of the electric motor failures occur at the start up. Most of them are caused by the over-heating of motor.
