The electrical performance data on the rating plate is only valid if the motor is connected to a liquid
cooling system. The requirements of the liquid cooling system are shown on a separate rating plate
located on the motor, see Figure 1. An example of a separate rating plate can be seen in Figure 3.

2.2. Expected lifetime
The expected lifetime is very dependent on the motor´s winding and bearing temperature. The lower the
temperature the longer expected lifetime. The insulation system for the motor is class H, which means
that the winding temperature should not exceed 180°C. If the winding temperature is kept below this
limit, the expected lifetime of the insulation system is at least 20,000 hours. The electrical performance
data on the rating plate, see Figure 2, is the continuous operation point (S1). Operating in this point will
not compromise the expected lifetime. As a simplified method, the S1 power in a duty cycle can be
calculated by the root mean square method:

means that the winding temperature should not exceed 180°C. If the winding temperature is kept
below this limit, the expected lifetime of the insulation system is at least 25,000 hours. The

So, in a duty cycle, the rated torque and power on the rating plate could exceed the short term
(peak torque and peak power) as long as the winding temperature do not exceed 180°C.
As mentioned in the Product description, the motor is equipped with temperature sensors in the
stator winding. In most inverters, it is possible to set a warning limit and a shutdown limit for the
winding temperature. To not compromise the expected lifetime, the values in Table 2 are
recommended.

The expected lifetime for bearings and external seals is not solely temperature dependent and
needs to be evaluated based on the duty cycle. Please contact your local ABB sales office for

NOTE: The warning and shut down limits are only valid for short term operation. Prolonged
operation at high stator winding temperatures will significantly impact the bearing grease
lifetime.
