Mixer and Agitator Drive - MC with Extended Bearing Distance (EBD)

sew-euro-07

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.

DR Motor - Modular AC Motors and Brakemotors

sew-euro-08

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.
