Electrical machine with magnetized rotor

An electrical machine comprising:

• a stator including a stator core and windings disposed on the stator core;
• and
• a rotor adapted to magnetically interact with the stator to promote rotation of the rotor about an axis, the rotor including a rotor core and a plurality of magnetized arcs supported by the rotor core, the plurality of magnetized arcs defining an outermost circumference, the rotor and the plurality of magnetized arcs including
• 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,
• a magnetization pattern of alternating magnetic poles formed on the plurality of magnetized arcs, the magnetization pattern including a first magnetic pole skewed with respect to a second magnetic pole to form an interpolar axis, the interpolar axis defining an axial section having a length,
• wherein a center of the interpolar axis is located at approximately half the length of the axial section, and
• wherein the center of the interpolar axis is located approximately on a center axis of the discontinuity.
