SEW-Eurodrive’s K-Series helical-bevel gearmotors contain high torque density with the highest efficiency available in a right-angle design. Instead of losing energy via the sliding friction of a worm gear, the K-series uses much lower rolling friction of helical and bevel gears. The result is minimum heat and maximum energy savings to the end user.

SEW-Eurodrive’s P2 series combination planetary gearmotor offers high torque with low output speed. The planetary half provides high output torque in a compact design. The gearmotor half provides additional ratio and integrates directly onto the input to eliminate a coupling and an adapter flange. The result is a very rigid, compact gear unit. To enhance design flexibility, the gearmotor input is available in either coaxial inline or right-angle.

In mixing and aerating applications, the impeller shaft is subject to large thrust and radial forces. Traditional mixer designs typically incorporate a radial bearing near or at the bottom of the impeller shaft and a thrust bearing at the top of the shaft. An alternate design uses an oversized gear unit. Either design is usually expensive.

SEW-Eurodrive’s Extended Bearing Distance (EBD) design offers a stronger bearing within the gear unit itself. Therefore, it is often unnecessary to oversize the gear unit.

Two solid shafts are available. For equipment containing an external radial bearing, the smaller diameter shaft can support large axial and moderate radial loads. For equipment with no external bearings, the larger diameter can support high radial and moderate axial loads. An alternative hollow shaft is available for moderate radial and moderate axial loads.

The low-inertia rotor design of SEW’s squirrel-cage DR motor and brakemotor provides outstanding system stability, tight control, and high-cycling capacity. In many cases, its high performance allows it to replace a servo motor.

With a patented dual coil design and specialized rectifiers, its fail-safe brake delivers extremely fast stopping and starting times with minimal drift. Moreover, its low-noise operation and quiet braking make it perfectly suited for theater applications.

Every DR motor frame is available with multiple brake sizes to optimize cost. Select higher torque for a stopping brake or lower torque for a VFD holding brake. Its various connector options make the DR motor especially suitable for automotive manufacturers.
