Product Description:

The MDD090B-N-040-N2M-110GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where rapid, closed-loop positioning is necessary in machine tools, packaging lines, and material-handling stations. The motor translates controller current commands into repeatable rotary motion and fits applications that demand high cycle rates with minimal mechanical transmission loss. This operating profile supports responsive axis behavior and consistent positioning during frequent starts, stops, and reversals.

The motor delivers a continuous standstill torque of 7.2 Nm, giving machinery steady-state holding capability without overheating. Under rated excitation, it reaches a nominal speed of 4000 rpm, so axis travel can be synchronized to high feed rates. A centering diameter of 110 mm simplifies concentric alignment of the flange to adjoining frames and helps keep radial runout low. Position and velocity data are returned through Digital servo feedback (DSF), enabling the controller to close both current and speed loops with high-resolution feedback. Power and feedback conductors mate through a single connector, and this plug-style interface simplifies cable connection when the unit is mounted with its connections on the left side of the housing. Motor size 090 and length code B identify the active core dimensions used for this torque class.

An integrated multi-turn absolute encoder tracks shaft position across power cycles, so homing routines are not required after every startup. The unit is supplied without a blocking brake, making it suitable for systems that rely on drive torque or external clamps for static holding. A configuration with a shaft seal helps keep lubricant inside the bearing zone and prevents coolant ingress during washdown. The output is a plain shaft, allowing backlash-free coupling with collets or bellows couplings. Standard balancing limits vibration at nominal speed, and the standard cast housing provides a rigid enclosure while maintaining the overall footprint used by the series.
