Power Transmission Rotary Joints

SPINNER's contactless power transmission rotary joints are a symmetrical rotating system for transmission of electric energy. Rotating power transmission is used to supply DC voltage to control systems, sensors, or other consumers on rotating shafts.

The power rotary joint works like a galvanically isolated DC voltage transmitter. It keeps the output voltage nearly constant over a wide input range, regardless of the load. A major advantage is the presence of a hollow shaft, thus permitting combinations with optical single-channel or multi-channel rotary joints for data transmission. The output has a short-circuit-proof and open-circuit-proof design.

This DC/DC converter of the power rotary joint conforms to all common industry standards with respect to safety, interference immunity, and emitted interference. DC/DC converters for 24 V are available for up to 300 W; converters for high output voltages and up to 11 kW are also available on request.
