Servomotor-gearboxes are ‘half the length’

22 December, 2015

Sumitomo (SHI) Cyclo Drive has collaborated with the Swedish motor manufacturer HDD Servo Motors to develop a compact, precision, hollow-shaft motor-gearbox that, they claim, is half the length of conventional rotary drives with comparable performance.

The FC Drive C25 combines the cycloid principle of the Sumitomo’s tilt-resistant Fine Cyclo gearboxes with compact motors based on HDD’s patented Stritorque technology. They say that the combination sets new standards for compactness and torque density.

The 174mm-long and 189mm-diameter motor-gearboxes are said to achieve an acceleration torque of 1,040Nm. They incorporate a 45mm-diameter hollow-shaft bore through which cables and media can be fed.

The combined motor-gearbox is due to go on sale later this year but samples have already been supplied to selected customers. Florian Butzmann, Sumitomo Cyclo Drive’s director of sales and marketing for the EMEA region, reports that the feedback has been “extremely positive”, adding that “the uncomplicated mechanical integration and high level of flexibility in combination with virtually any power electronic is highly valued”.
