摘要

The unit has the motor provided with at least one integrated fluid and/or electrical line in the form of connection drillings and discs (27, 28, 30). It contains precision roller bearings and a resolver or an optical encoder as a displacement measuring system. The motor is designed with an outer rotor and a hollow shaft (24).A separate servo-intensifier is provided and an electronic regulating speed, the acceleration or retardation and the torque. A rotary distributor (3) is rotatable about the fixed shaft of the distribution flange (23). Annular discs are located in the central bore of the distributor (3). An electric signal and power supply results across an integrated slip ring capsule. Sensors and other electrical units are accessible from the turntable (1).
