Abstract
An interior permanent magnet electric motor forms a buried angle of a left permanent magnet of a slot part of a rotor differently from a buried angle of a right permanent magnet of the slot part of the rotor, so as to reduce torque ripple while sufficiently maintaining motor efficiency as compared to an I-type rotor to effectively improve noise, vibration, and harshness performance.
