Product Description:

The MDD090B-N-040-N2L-110PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat and cataloged in the MDD Synchronous Motors series. Intended for use with digital drive controllers, it translates controlled current into precise rotary motion for machine tools, packaging axes, and material-handling stations. The B-length 090-frame housing allows a compact build while still providing the centering flange size required for direct coupling to driven equipment in automated cells. It is suited to closed-loop axes that need repeatable positioning, stable low-speed operation, and quick response to changing load conditions. The motor format also suits installations where the drive, coupling, and machine frame must fit within a limited mounting envelope.

At a nominal speed of 4000 rpm, the rotor can follow high-frequency command changes while maintaining accurate motion, supporting rapid positioning cycles. Continuous standstill torque of 7.2 Nm lets the shaft resist static loads during dwell periods. Power and feedback cabling exit on the right side, an orientation that can simplify routing where cable runs must stay clear of guards or nearby machine members. Electrical power reaches the windings through a field-replaceable connector, so the motor can be disconnected without opening the housing. Position and speed are reported via digital servo feedback, enabling the controller to apply closed-loop corrections for accurate velocity and torque regulation.

A centering diameter of 110 mm aligns the motor concentrically with gearboxes or flange plates, and the shaft transmits torque through a machined keyway. Because the unit ships without a blocking brake, applications that must hold position at power-off need external braking or sustained drive current. Contamination ingress at the output end is limited by a design with a shaft seal. The housing uses standard dynamic balancing and a single-ended shaft arrangement to support smooth rotation and straightforward coupling. This arrangement supports direct coupling to pulleys, gear stages, and other rotary transmission elements used on automated axes. The motor length code B indicates an electromagnetic stack suited for medium continuous duty loads.
