Helical gearmotors
Make use of the advantages of the compact combination of powerful helical gear units and AC motors. Our helical gearmotors of the series R..DR.. set themselves apart with their finely stepped gear unit ratios and variety.
Covering 6 specifications of single-stage reducers and 14 specifications of 2-stage and 3-stage reducers, the R series of helical gear reduction motors perfectly meet the requirements of power and installation space.
