DRM.. torque motors
DR.. series: DRM.. design
Features The DRM.. design (product designation „torque motor“) is a 12-pole motor that can be opera- ted continuously and thermally safely on a 3-phase system even when the rotor is blocked. Every torque motor is available with three rated torques.
This allows for the manifold requirements of various applications to be easily met
– Many additional features of the AC motor modular system are available
– Can be combined with the 7-series of the modular gear unit system from SEW-EURODRIVE

DRK.. single-phase motors
NEW: DR.. series: DRK.. design
03
Features | The DRK.. design design can be used in 1× 230 or 1× 220 V single-phase supply systems. The running capacitor installed in the terminal box allows for operation under many demanding ambient conditions. SEW-EURODRIVE also offers the ET56 and the ER63. | ||
