Abstract
The present disclosure relates to an electric drive motor () for a vehicle. The electric drive motor () has a stator () having a plurality of slots (); and a rotor () having a plurality of poles (). The poles () each have at least a first permanent magnet () centred on a d-axis of the pole (); and a plurality of flux barriers () for disrupting at least an n-th order torque harmonic of the electric drive motor (). Proximal to an outer surface of the rotor (), a first angular period (x11) between first and secondary flux barriers is defined by the equation (xi1=tao/n1), whereby: (xi1) is the first angular period; (tao) is the pole step; and n1 is an order number of a torque harmonic to be disrupted.
