US20140246943A1 - Optimum rotor skew angle for an electric machine - Google Patents
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.
