Advantage

The available built-in encoders for the DR.. motors series that can be installed on the B-side between endshield and fan wheel are unique. With this solution the user does not have to provide for additional space as it is the case with add-on speed sensors*.

MOVITRAC standard inverter in combination with the “simple positioning” application module can replace applications that, up to now, have been realized with creep/rapid speed switch-over with initiator evaluation.

Features

To protect motors and gear units that are subject to severe environmental influences,

SEW-EURODRIVE offers possibilities to increase the resistance of highly stressed surfaces.

KS corrosion protection

Measures to increase the resistance to corrosion:

– All retaining screws that are loosened during inspection or maintenance work are made of stainless steel

– Nameplates are made of stainless steel and various motor parts are coated with a finishing varnish

– The flange contact surfaces and shaft ends are treated with a temporary rust preventive

– In addition, clamping straps are used for brakemotors

OS surface protection

In addition to the standard surface protection, motors and gear units are optionally available with surface protection OS1, OS2, OS3 or OS4. This makes the gearmotors well equipped for operation under various ambient conditions.
