Abstract
A permanent magnet motor includes a rotor configured to rotate about a stator axis and having N pairs of permanent bar magnets each arranged therein and in a V-angle configuration defining a V-angle (θ) therebetween and corresponding to one of N rotor poles, wherein N is greater than one. An adjustment system is configured to adjust the V-angle between each pair of the N pairs of permanent bar magnets between at least a first V-angle (θ) and a different second V-angle (θ). A controller is configured to control the permanent magnet motor and the adjustment system to (i) mitigate noise, vibration, and/or harshness (NVH) of the permanent magnet motor and (ii) improve efficiency of the permanent magnet motor at high speed operating regions or improve torque of the permanent magnet motor at low speed operating regions.
