Product Description:

The MDD090B-N-030-N2M-130PR2 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as a rotary actuator that converts controlled electrical input from a servo drive into mechanical motion for positioning and velocity tasks in automated machinery. The model follows a standard housing design, uses standard rotor balancing, and is supplied with a shaft seal to protect internal components during continuous industrial operation. The synchronous motor layout supports accurate response to commanded changes in speed and position.

This unit delivers a continuous standstill torque of 7.2 Nm, giving the drive enough holding force for static loads without overheating. At its rated operating point, the rotor reaches a nominal speed of 3000 rpm, matching common inverter output frequencies used in packaging, printing, and material-handling axes. Mechanical alignment to the driven equipment is simplified by a centering diameter of 130 mm, and the power and feedback lines terminate on a single connector to reduce wiring complexity. Position verification is handled through digital servo feedback (DSF) combined with an integrated multi-turn absolute encoder, supporting repeatable accuracy even after power loss. Using one connection point keeps cable routing compact, and the motor has frame length B with side B closed because the shaft end is provided only on the drive side.

An electromechanical blocking brake supplies 11.0 Nm of holding torque, allowing vertical or safety-critical axes to maintain position when the drive is disabled. This supports load retention when drive torque is removed. The cylindrical output shaft is machined with a keyway so torque can be transmitted through standard keyed couplings. All external cabling exits on the right side of the stator housing to fit cabinets that route conduits along the motor flank. This layout helps keep cable routing clear of the shaft end during installation.
