Rotary joints for power transmission

The companies' innovations in the fields of power transmission together with the technical know-how and top-quality claim has allowed SPINNER to become one of the leading rotary joint manufacturers worldwide.

SPINNER's contactless power transmission system is a rotationally symmetric system for contactless transmission of electrical energy. This transmission system is used for the DC voltage supply of control systems, sensors or other consumers on rotating shafts.

The functioning of the transmission system corresponds to that of a galvanically isolated DC voltage transmitter. It keeps the output voltage nearly constant regardless of the load and over a wide input voltage range. The output has a short-circuit-proof and open-circuit-proof design. A major advantage is the presence of a hollow shaft, which means that combinations with optical single-channel or multichannel rotary joints are possible for data transmission.

This DC/DC converter meets all standards common in the industry with respect to safety, interference immunity and emitted interference.

  • Rotary transmission of up to 6 kilowatts for intermediate circuit voltages up to 500 V DC
  • Transmission of industrial 24V DC voltages at up to 300 W
  • Combinations with optical single-channel or multi-channel rotary joints for data transmission available

SPINNER RF components meet highest standards

SPINNER applies extremely high standards with regard to quality, engineering, materials and manufacturing e.g. DIN EN ISO 9001 - Quality Management, DIN EN ISO 14001 - Environmental Management and ISO 50001:2011 - Energy Management. This enables us to offer rotary joints with the best possible performance and lowest possible intermodulation (Low PIM), even under the harshest environmental conditions.
