Product Description:

The MDD090A-N-040-N2M-110GB2 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is supplied as a motor for digital drive controllers and is intended for tightly regulated rotary positioning in automated machinery. The unit uses standard balancing to minimize vibration, and its housing has a standard sealed design. An integrated multiturn absolute encoder provides position data to the drive, while a blocking brake is fitted to secure the load when power is removed. It is suited to servo applications where the controller must maintain accurate position feedback during repeated starts, stops, and speed changes. This arrangement supports closed-loop motion on axes that require retained position information and secure holding at a standstill.

The motor reaches a nominal speed of 4000 rpm, allowing high-cycle production lines to maintain rapid indexing without overshoot. At standstill, it can deliver 3.7 Nm of continuous torque, which is the available torque for stationary load demand within thermal limits. For emergency stops or vertical axes, the integrated brake supplies 11.0 Nm of mechanical holding torque. A centering diameter of 110 mm positions the motor accurately on machine frames, and the frame size is 090. The motor uses the short A housing length, which helps reduce overall mass while keeping the mounting format of the 090 frame. A shaft seal is fitted to help block lubricant migration and airborne contaminants.

Cabling exits on side B of the enclosure, and a single screw-lock connector carries both power and signal conductors, which helps cable routing in confined panels. Using one connection point reduces the number of separate cable entries at the motor housing and keeps the interface compact. The shaft is a plain shaft without a secondary shaft end, so it can be used with standard friction hubs and other clamping elements. Motor feedback is provided by digital servo feedback (DSF), allowing the drive to resolve multi-turn position without additional sensors.
