Rotor of disc motor

The invention relates to the field of motors, in particular to a rotor of a disc motor. The rotor comprises a yoke disc (1) and a permanent magnet group on the yoke disc (1), and the permanent magnetgroup is circularly distributed on the yoke disc (1). Replacing the consumption of the exciting magnetic field of the conventional motor with permanent magnetism is the core of truly ultra-high efficiency and high energy conservation of the permanent magnetic coreless disc motor; the power density of the motor using the rotor is high, and the rotor is also a good choice for applications where sizeand weight are required; and the motor using the rotor has low noise and strong controllability, can output constant rated torque in the full working range, and achieves direct heavy load start. 本发明涉及电机领域，尤其涉及种盘式电机的转子；该转子包括磁轭盘(1)以及位于所述磁轭盘(1)上的永磁体组，所述永磁体组在所述磁轭盘(1)上呈圆形分布；用永磁替代传统电机励磁磁场的消耗，这就是永磁无铁芯盘式电机真正超高效率、高节能的核心；采用本发明所述转子的电机功率密度高，对于体积和重量有要求的地方应用而已是很好的选择；噪音低；可控性强；可以在全工作段输出恒定的额定转矩，直接重载启动。
