Rotating connector for e.g. angular ball bearing, utilized as pivot bearing e.g. in construction of articulated bus, has electrical coil that is fixedly connected to outer bearing ring and magnets that are connected to inner bearing ring

摘要

The connector has a roller bearing with an outer bearing ring (1) and an inner bearing ring (2), where roller bodies (3) i.e. bearing balls, are arranged between the rings. A direct drive i.e. three-phase brushless synchronous motor, has a stator with an electrical coil (6) and a rotor with multiple permanent magnets (8) for a rotary drive of one of the rings. The coil is fixedly connected to the ring (1) and the magnets are connected to the ring (2). The ring (2) serves as an output shaft (9) or a magnetically conductive connecting ring. The ring (1) is made of aluminum.
