Abstract
An electric machine rotor including a rotor core having a plurality of magnets and several pairs of elongated slots circumferentially distributed on the rotor core. Each pair of elongated slots jointly forms a V-shaped configuration with an opening facing an outer periphery of the rotor core. Each elongated slot includes a mounting portion that matches the shape of the magnet and an end hole located at an end of the elongated slot pointing to the outer periphery. The end hole includes a main body area and a lobe area, and the lobe area extends from the main body area toward outside of the V-shaped configuration until it is partially located outside a side extension line of the mounting portion.
