Classification of insulation for electric motor.
Electric motor manufacture design the winding insulation class depend on technical aspect and user application.For good grade of insulation,the cost is higher.So the engineer selects the electric motor based on applications and working area temperature characteristics.
The temperature for electric motor is depend on the fans performance and design.Manufacture normally design the cooling fan according to the duty,type of application and load on the motor.Theoretically the load on motor affected the temperature of motor.
The conclusion is,when we selected the class of insulation for electric motor,several factor must be consider are :
Type of load ( pump,turbine,compressor)
Working area ambient temperature
Application of motor
Room condition
