摘要： A method of forming a rotor includes inserting a conductor bar into a slot defined by a lamination stack to define a gap between the conductor bar and the lamination stack. The method further includes, after inserting, swelling the conductor bar within the slot to fill the gap and form the rotor. A rotor is also disclosed.

摘要： An electric machine includes a stator core defining a number of stator slots (S) extending along a longitudinal axis and angularly spaced about the longitudinal axis. The machine includes a rotor assembly rotatable relative to the stator core and defining first and second ends. The rotor assembly includes a plurality of laminations stacked between the first and second ends. Each respective one of the plurality of laminations defines a number of rotor slots (R) positioned along an outer periphery. A stator slot pitch is defined as 360 divided by the number of stator slots (S). A rotor slot pitch is defined as 360 divided by the number of rotor slots (R) in each respective one of the plurality of laminations. The laminations are skewed relative to each other. An optimal rotor skew angle is determined by the greater of the stator slot pitch and rotor slot pitch.

摘要： A BAS machine that includes a specific combination of the number of stator slots to the number of rotor bars to reduce torque ripple without the need for skewing the rotor bars. Particularly, the ratio of the number of stator slots to the number of rotor bars is selected to prevent first and second order harmonics between the stator slots and the rotor bars, where the ratio includes 36/26, 54/44, 72/56, 72/58 or 72/62 for a six pole machine, 48/36, 72/52, 72/58 or 84/86 for an eight pole machine, and 60/44 or 60/46 for a ten pole machine.
