1.Moment of inertia

The calibrated inertia on the sample refers to the inertia reduced to the motor shaft.

2.Protection grade

Pay attention to this indicator for special applications

3.Operating temperature range

This is an important indicator, and the range indicated on the sample is mainly determined by the lubrication system, which will be discussed in more detail in the following section on lubricants. It should be noted that all the indicators in the sample are not the same in this range, which usually refers to values at 25℃.
