Product Description:

The MDD090B-N-030-N2M-110PL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supplies controlled torque and speed for positioning axes in automated equipment. The 090 frame uses a standard housing and standard balance grade, while length code B indicates the rotor stack depth and the related thermal capacity. This layout suits compact multi-axis machines where installation space is limited and stable servo response is required during repeated motion cycles.

Its continuous standstill torque is 7.2 Nm, which shows how much load the rotor can hold while energized without exceeding rated temperature. During operation, the shaft can reach a nominal speed of 3000 rpm, supporting direct coupling to common gear stages and motion elements. Precise centering is provided by a 110 mm pilot diameter that fits matching mounting flanges. Power, feedback, and protective earth conductors exit on the left side, and a single keyed connector combines these circuits to reduce wiring space. A shaft seal is installed to help keep oil and contaminants away from the internal components, while the keyed shaft transfers torque through positive mechanical engagement.

Rotary position is tracked by an integrated multi-turn absolute encoder, which reports up to 4096 turns through digital servo feedback (DSF) so the controller can retain position data after power loss. Because the motor is supplied without a blocking brake, static holding must be provided by drive current or by an external clamping device when the axis is stopped. The output geometry is configured without a side B shaft end, allowing the rear bearing plate to sit closer to machine walls or mounting surfaces. This arrangement leaves the rear side clear of a second shaft projection and can simplify installation where space behind the motor is restricted.
