常见问题

What is the purpose of insulation in stator assemblies?

The insulation system prevents electrical short circuits between windings and to ground, reduces energy losses, and ensures safe operation by maintaining dielectric integrity under operating conditions.

How do you determine the thermal class of insulation?

Thermal class (e.g., Class F, H) is determined by standardized thermal endurance tests (IEC 60034-18) that measure the insulation's ability to withstand specific temperature ranges over its service life.

What are common failure modes in insulation systems?

Common failures include thermal degradation, partial discharge erosion, mechanical damage from vibration, contamination, and moisture absorption leading to reduced dielectric strength.
