Actual heating temperature of the motor
Motor temperature refers to the actual heating temperature of each part of the motor. It has a great impact on the insulation material of the motor. Excessive temperature will cause insulation aging to shorten the motor life and even cause insulation damage. In order to prevent the insulation from aging and damage, the temperature of each part of the motor winding and other parts is subject to irregular restrictions. This temperature limit is the allowable temperature of the motor.The temperature of each part of the motor is also related to external conditions. The temperature rise is the value that the temperature of the motor is higher than the ambient temperature.
θ = T2-T1 where θ ------- temperature rise
T1 ------- winding temperature under actual cooling state (ie ambient temperature, room temperature is not allowed to exceed 40 ℃);
T2 ------- winding temperature under heating.
