Motor temperature is the actual heating temperature of each part of the motor, a great impact on the motor insulation materials, high temperature insulation aging will shorten motor life, and even cause dielectric breakdown. For the insulation without aging and damage to the motor windings and other made a part of the temperature limit from time to time, this temperature limit is permissible temperature of the motor.
     Motor temperature level ministries but also with external conditions, the motor temperature rise is higher than the ambient temperature value
