  • Stator with carbon fiber-based insulation strips
    Patent number: 11699940
    Abstract: A stator includes a stator core having an annular portion and a plurality of teeth extending radially inward from the annular portion, such that a slot is defined between each pair of adjacent teeth. Each of the teeth includes a pair of side surfaces that face in opposite directions. The stator core also includes a plurality of inner surfaces on the annular portion, each inner surface arranged between facing side surfaces of two adjacent teeth of the plurality of teeth. The stator also includes a plurality of thermally conductive, carbon fiber-based insulation strips. Each insulation strip is arranged within one of the slots for covering the inner surface and the facing side surfaces of two adjacent teeth. The stator also includes a plurality of windings wound around the respective teeth.
