Product Description:

The MDD090B-N-040-N2M-130PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controlled mechanical motion for positioning axes, conveyors, and tooling in automated lines. The unit uses connector-based power and feedback connections, which help keep cabling organized around the motor body. Its standard housing and B length make it suitable for compact machine layouts that need repeatable closed-loop motion.

Mechanical mounting is centered by a 130 mm pilot diameter that matches precision flanges. At standstill, the motor can supply 7.2 Nm of continuous torque, which supports holding force and low-speed operation without additional gearing. The motor has a nominal speed of 4000 rpm, allowing rapid indexing in high-cycle machines. It uses frame size 090, and positional data is returned through digital servo feedback (DSF), which sends high-resolution rotor angle information to the drive. The keyed shaft end supports positive torque transmission to couplings or pulleys, and the left-side connector orientation can simplify cable routing in dense multi-axis cabinets.

The motor is supplied without a blocking brake, so the load must be held by external hardware or drive torque when power is removed. Position repeatability is aided by the integrated multi-turn absolute encoder, which retains the revolution count through power cycling and supports immediate position availability after startup. A shaft seal helps limit contaminant entry at the rotating interface during normal operation. Dynamic behavior is supported by standard balancing, and the motor has a shaft end on side A only, with no shaft on side B, which simplifies coupling to driven elements while reducing unnecessary rotating mass.
