The motor gearbox unit DCT is a compact drive consisting of a motor combined with a cycloid gearbox. The cycloid gearbox unites high precision with excellent stiffness and a high overload capacity in a small installation space. Due to the combination with a specially developed synchronous motor integrated in the same housing, the adavantages of the cycloid gearbox regarding power density and size can be optimized. The motor gearbox unit is especially suitable for applications in robotics, machine tools and packaging machines, where a high power density and a small size are required.
