Abstract
The utility model discloses an electromotor rotor comprising a rotor punching sheet, magnetic tiles and permanent magnet body grooves, wherein the cross section of each magnetic tile is shaped like a right-angle trapezoid, gaps are arranged between two ends of the magnetic tiles and the permanent magnet body grooves, and therefore air gaps are formed, rotor external outline corresponding to neighboring permanent magnet body grooves is arc in shape, at least two magnetic tiles are arranged in each permanent magnet groove, and baffle plates which are not magnetically conductive are adopted for separating neighboring magnetic tiles. The electromotor rotor is characterized in the magnetic tiles having cross sections shaped like right-angle trapezoids are provided by the electromotor rotor, and therefore forward direction rotary torque can be improved, and magnetic field utilization rate is raised; through the arc-shaped rotor external outline, waveforms of air gap magnetic fields can be improved; and the baffle plates which are not magnetically conductive are adopted for separating the neighboring magnetic tiles, magnetic leakage phenomena of the magnetic tiles can be reduced, and therefore an air-gap flux density sine degree is guaranteed.
