High-power multiphase electric machine with reduced mutual inductance interaction

A vehicle comprising:

• a motor controller;
• and
• a six-phase electric motor electrically coupled with the motor controller and comprising:
• a stator and a rotor configured to operate, by the motor controller, as a first three-phase electric motor and a second three-phase electric motor,
• the first and second three-phase electric motors coupled with each other via a fractional slot combination with concentrated windings,
• the rotor comprising a plurality of V-shaped magnets, the number of V-shaped magnets equal to a number of poles in the six-phase electric motor, wherein each of the V-shaped magnets includes five (5) axially segmented components that are in a skewed orientation with respect to each other, wherein the skewed orientation defines a skew angle of 25 electrical degrees.

A six-phase electric machine comprising:

• a stator and a rotor configured to operate as a first three-phase electric machine and a second three-phase electric machine, the first and second three-phase electric machines coupled with each other via a fractional slot combination with concentrated windings,
• wherein an electrical separation between the first and second three-phase electric machines is 15 electrical degrees,
• wherein the rotor includes a plurality of V-shaped magnets, the number of V-shaped magnets is equal to a number of poles in the six-phase electric machine, and each of the V-shaped magnets includes five (5) axially segmented components that are in a skewed orientation with respect to each other, wherein the skewed orientation defines a skew angle of 25 electrical degrees, and
• wherein having the electrical separation of 15 electrical degrees facilitates a winding factor of at least 80% and a slot harmonic distortion of less than 50% for the six-phase electric machine.
