Hairpin winding electric machine

An electric machine includes a stator core defining slots and a winding disposed in the core and having three phases. Each of the phases has at least two parallel paths including hairpins interconnected to form at least two continuous circuits between a terminal and a neutral. The hairpins of each p...

Zusammenfassung:An electric machine includes a stator core defining slots and a winding disposed in the core and having three phases. Each of the phases has at least two parallel paths including hairpins interconnected to form at least two continuous circuits between a terminal and a neutral. The hairpins of each path include: a first type of hairpins (first hairpins) each having first and second legs spaced apart by a span of five slots; a second type of hairpins (second hairpins) each having first and second legs spaced apart by a span of seven slots; and a third type of hairpins (first hairpins) each having first and second legs spaced apart by a span of five or seven slots.
