Winding insulation and maintenance
– silicon rubber as high temperature material. The common types of insulating materials in use for electric motors are E and B for small motors and F for medium sized and large ones. General industrial practice, however, is to limit the temperature to class B limits, even if class F insulation is used. Insulation class A, previously in use ...
