Product Description:

The MDD090B-N-040-N2M-130GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary power to positioning and feed axes used in packaging lines, material-handling gantries, and other automated equipment where commanded motion must match feedback with minimal delay. Mechanical balance is kept to a standard grade, and the motor uses size code 090 with length code B to maintain a compact profile for tight mounting spaces.

This model develops a continuous standstill torque of 7.2 Nm, giving the drive enough holding force to support moderate static loads without extra gearing. During operation, it can reach a nominal speed of 4000 rpm, allowing rapid cycle times when paired with suitable inverters. The centering pilot measures 130 mm, which provides the locating fit against the machine frame and helps control radial runout. Power and feedback conductors exit on the rear face referenced as Side B, and a single plug-in connector simplifies cable routing. Positional data are exchanged through Digital servo feedback (DSF), so the drive controller receives high-resolution signals without additional interface modules.

An integrated multiturn absolute encoder tracks shaft angle over multiple revolutions, enabling homing-free restart after power loss. The motor is supplied without a blocking brake, so any required static holding must be provided by the drive or external locking devices. A Standard housing encloses the stator and routes heat to the mounting surface, while a shaft seal helps keep internal components isolated from coolant spray and dust. The output end uses a plain shaft, and the design omits a secondary shaft end on Side B, reducing overall length and eliminating unneeded couplings.
