Motor Protection : Over temperature

Motor temperature is one of the factor that we should monitor and make sure it running in a normal range.It is closely related with winding temperature.If temperature is highly from standard value,it can cause a winding insulator damage or weak.

From that damage,it will make the internal short circuit between winding phase and can cause a serious damage for an electric motor.

What is the main reason for the motor overheat or over temperature?Normally it cause due to a high ambient temperature,under sizing motor capacity,not suitable voltage rated,running in overload and bearing jammed. read more
