Abstract

A tangential rotor of a rotary motor comprises a rotating shaft and a rotor formed by laminated iron cores. The laminated iron cores are equipped with a plurality of permanent magnet pole portions that rotate around the axis of the rotating shaft and magnetize in a circumferential manner around the rotor corresponding to the axis. The permanent magnet pole portions are embedded in the laminated iron cores through permanent magnet grooves. One side of each permanent magnet groove, close to an air gap, is connected or disconnected with each laminated iron core. A distance between every two adjacent permanent magnet grooves close to one side of the rotating shaft is 0.1-5 millimeters in circumferential width. Every two adjacent permanent magnet pole portions are opposite in polarity. A distance between every two adjacent permanent magnet grooves close to one side of the rotating shaft is 0.4-3 millimeters in circumferential width. According to the tangential rotor, the laminated iron cores are provided with the permanent magnet grooves used for embedding the permanent magnet pole portions, and the adjacent permanent magnet pole portions are opposite in polarity. The tangential rotor of a rotary motor is simple and reasonable in structure, allows magnetic leakage of a magnet to be minimized, enables the utilization rate of the magnet to be increased, helps to solve problems that the rotating shaft needs a stainless steel material or a magnet shield copper sleeve, and enables manufacture costs to be effectively reduced.
