The CIV (Corona Inception Voltage) values of the industrial motors will affect the total power cable length between the drives and the motors, but the motor Temperature Class will not directly affect the total power cable length between the drives and the motors. Class B, Class F,or Class H are the insulation classes related to temperature.
Insulation system The "heart" of a motor design is the winding insulation system. Siemens GP100A motors feature: • A proprietary, inverter-rated, Class F insulation system with a Class B temperature rise @ 1.0 service factor. • Only the finest materials and …
The insulation class describes a motor's ability to withstand temperatures over time. B, F, and H are commonly used insulation types. Letters occurring later in the alphabet represent insulation that is better able to withstand temperature.

tens of thousands of hours with Class H insulation Temperature Tolerance Class B is the most common insulation class used on most 60 cycle US motors. Temperature Tolerance Class F is the most common for international and 50 cycle motors.
Class F (or better) insulation system is common for motor winding insulation. With conservative motor design, a 'Class B' temperature rise is quite achievable. For a 1.15 S.F. motor wound with Class F insulation, a Class B temperature rise at full load translates to a thermal margin of 155-(40+90) = 25°C.

General Motor Knowledge Part 24 Insulation Class 'B2' by Lynn R. Dutro November 21, 1994 GMK24.wp5 The insulation system in a Morrillmotor, does three things. It provides electrical separation between the energized windings and the outside housing of the motor, the endbell. The insulation system isolates one winding turn from another.
This is determined by, the ambient temperature, the heat generated at fully loaded conditions (temperature rise), and the thermal capacity of the motor insulation. These materials are classified as A, B…

For example, an 80°C rise is often referred to as a 'Class B', as 80°C is the maximum allowable temperature rise for a 1.0 S.F. motor with Class B insulation and a 40°C ambient temperature. This practice means that a motor with Class F insulation and an 80°C rise is referred to as an 'F/B' motor.
