Rotor for a Brushless Direct-Current Motor, Particularly for an Electric Motor of the Inner Rotor Type, and Electric Motor Comprising Such a Rotor

摘要

The disclosure 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/(2 pm), 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 disclosure, the winding of the rotor is connected in a delta connection.
