Abstract

The utility model provides a same-polarity type rotor of a rotary motor. The rotor is composed of a rotary shaft and a laminated iron core. Multiple first permanent-magnet pole portions and multiple second permanent-magnet pole portions are arranged in the laminated iron core, wherein the multiple first permanent-magnet pole portions rotate along the axis of the rotary shaft and carry out magnetization along the rotor circumference relatively to the axis, and the multiple second permanent-magnet pole portions rotate along the axis of the rotary shaft and carry out magnetization along the rotor circumference or along the rotor radial direction relatively to the axis. The amount of the second permanent-magnet pole portions is half of that of the first permanent-magnet pole portions. Polarities of adjacent first permanent-magnet pole portions are opposite, polarities of the second permanent-magnet pole portions are all the same, and poles of the second permanent-magnet pole portions which face the rotor are the same in polarities. The first permanent-magnet pole portions are embedded in the laminated iron core via first permanent magnet grooves, and the second permanent-magnet pole portions are embedded in the laminated iron core via second permanent magnet grooves. The rotor of the utility model is simple and reasonable in structure, is able to reduce magnetic leakage phenomenon of magnets, improves the utilization rate of the magnets, solves the problem that the rotary shaft needs to be sleeved with stainless steel materials or magnet-separating copper sleeves, and effectively reduces the production cost.
