Insulation system and method of insulating

An electric machine, comprising:

• a stator;
• a rotor;
• a plurality of windings;
• and
• an insulation system comprising:
• at least one first insulation section including at least one first insulation element, the first insulation element being configured to be applied to at least a portion of a first winding type of the plurality of windings, and the first insulation element having a first insulation thickness;
• and
• at least one second insulation section including at least one second insulation element, the second insulation element being configured to be applied to at least a portion of a second winding type of the plurality of windings, and the second insulation element having a second insulation thickness greater than the first insulation thickness of the first insulation element, wherein
• the first insulation section is arranged adjacent the second insulation section in a circumferential direction, and
• the first insulation section does not include the second insulation element.

A method of insulating a plurality of windings of an electric machine, the method comprising:

• applying a first insulation element to at least a portion of a first winding type of the plurality of windings in a first insulation section, the first insulation element having a first insulation thickness;
• applying a second insulation element to at least a portion of a second winding type of the plurality of windings in a second insulation section, the second insulation element having a second insulation thickness greater than the first insulation thickness of the first insulation element;
• and
• arranging the first insulation section adjacent to the second insulation section in a circumferential direction, wherein
• the first insulation section does not include the second insulation element.
