ROTOR FOR A BRUSHLESS DIRECT-CURRENT MOTOR, PARTICULARLY FOR AN ELECTRIC MOTOR OF THE INNER ROTOR TYPE, AND ELECTRIC MOTOR COMPRISING SUCH A ROTOR

The invention relates to a rotor for a brushless direct-current motor comprising a shaft, a rotor core arranged on the shaft, the rotor core acting as a return body, and a ring magnet which surroundsthe rotor core and is attached to same. The ring magnet is in the form of a circular disk, a radial direction and a peripheral direction being defined by the circular disk. Furthermore, a hole count qis defined by the equation q=N/(2pm), N being the number of grooves in the rotor, p being the number of pole pairs of the rotor, and m being the number of phases. According to the invention, the winding of the rotor is connected in a delta connection. 本发明包括一种用于无刷直流电机的转子，其包括：轴；布置在轴上的转子芯，其中，转子芯用作轭体；以及固定在转子芯上且包围转子芯的环形磁体。环形磁体构成为圆环盘形，其中，通过圆环盘形来限定径向方向和圆周方向。此外，还通过等式q＝N/(2pm)限定孔数q，其中，N代表在转子中凹槽的数量，p代表转子的极对数，以及m代表相数。根据本发明设置，转子绕组连接为三角形连接。
