Product Description:

The MDD090B-N-040-N2M-130GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power from an inverter into rotation that positions or transports loads in automated machinery. A standard housing and standard dynamic balancing simplify mounting, and the motor is delivered without a blocking brake so any static holding requirement must be satisfied by the external mechanism. This arrangement suits axes that rely on the drive and machine mechanics for controlled stopping and holding during repeated motion cycles.

This model operates up to 4000 rpm, a nominal speed that matches high-throughput packaging or pick-and-place cycles. At standstill it can deliver 7.2 Nm of continuous torque, providing stable force for indexing tables or tensioning rolls. Installation aligns on a 130 mm centering diameter, and the power and feedback plugs are positioned on the right side to keep cable runs clear of adjacent axes. All electrical terminations are made through a single connector, reducing enclosure penetrations and simplifying cable routing. Position data is returned to the drive over digital servo feedback, allowing high-resolution control loops without separate feedback wiring.

An integrated multi-turn absolute encoder supplies position information across power cycles, eliminating homing moves when the machine restarts. The motor uses a durable shaft seal to guard the interior against coolant splash or fine dust, and torque is transmitted through a plain shaft that accepts clamp or keyless couplings. Motor size 090 and length code B give a compact footprint, while the shaft end remains single-sided so no side B extension occupies additional space. Standard housing construction and the integrated feedback arrangement support use with compatible digital drive systems on compact servo axes where installation space is limited.
