Nowadays, electric motors are used in almost every application, controlled by electrical drives. However, not all motors operate for the same amount of time. Some run continuously, Such as S1
Total GD2 is the sum of load GD2 + Motor GD2 + Coupling GD2 , Torque Speed Curve
NSULATION CLASS
The IEC 60085 specifies that an Insulation system permanently submitted to its Insulation Class temperature has a life expectancy of 20 000h.
TEMPERATURE RISE CLASS
The temperature rise class is the maximum allowed difference between the measured temperature, after temperature stabilisation, of one of the active generator components (stator or rotor copper) and the cooling fluid temperature (e.g. ambient air temperature for instance, at 40°C).
