Abstract (en)

[origin: WO2018184769A1] 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 surrounds the 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 q is 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.
