Product Description:

The MDD090A-N-040-N2M-110GL2 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it delivers repeatable torque and speed so automated axes in packaging lines, handling robots, or machining centers can follow commanded profiles accurately. The unit includes an integrated multi-turn absolute encoder for position capture and a blocking brake that holds the shaft when the controller is disabled, supporting safe standstill conditions during power loss or emergency stops.

The mounting interface uses a pilot bore of 110 mm in diameter, and the rotor is balanced to the standard grade to help keep vibration low during operation. Under continuous duty, the motor can supply 3.7 Nm of standstill torque, providing enough force for indexing tables or clamp actuators without overheating. During normal operation, the shaft can reach a rated speed of 4000 rpm, enabling fast cycle times with tight velocity control. The integrated brake provides 11.0 Nm of holding torque, and all electrical connections exit on the left side of the housing to keep wiring clear of moving parts.

The feedback channel uses digital servo feedback (DSF), allowing the controller to read absolute position data without separate resolver wiring. A single connector handles power, brake, and feedback conductors, which simplifies assembly in modular cabinets and reduces the number of separate cable entry points. The motor uses a plain shaft that accepts collet or clamp couplings, and the mechanical interface is supplied with a shaft seal to limit the ingress of cutting fluid or dust. Size 090 geometry, length code A, a standard housing, and the absence of a side-B shaft end support installation in confined machine frames.
