ABSTRACT:
An electrical machine comprises a stator and a rotor. The rotor is adapted to magnetically interact with the stator to promote rotation of the rotor about an axis. The rotor includes a rotor core and a plurality of magnetized arcs supported by the rotor core. The plurality of magnetized arcs defines an outermost circumference. The rotor and the plurality of magnetized arcs include a first magnetized arc, a discontinuity disposed adjacent to the first magnetized arc along the outermost circumference, a second magnetized arc disposed adjacent to the discontinuity along the outermost circumference, and a magnetization pattern of alternating magnetic poles formed on the plurality of magnetized arcs. The magnetization pattern includes a first magnetic pole skewed with respect to a second magnetic pole to form an arc of magnetization skew.
