Product Description:

The MDD090B-N-040-N2M-130GL1 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies closed-loop rotary motion for positioning, feed, and spindle axes. In automated machinery, the motor converts electrical power from the drive into precise mechanical shaft rotation and supports repeatable speed and torque control across a broad duty cycle. Its synchronous design allows rapid response to changing command signals during starts, stops, and reversing moves. This makes it suitable for packaging machines, transfer systems, machine tools, and other equipment that depends on precise motion with consistent loop stability.

A centering diameter of 130 mm aligns the motor housing with mating machine frames for concentric mounting. Power, brake, and feedback leads exit through a connector on the left side, which helps keep cable routing clear of moving parts. When energized, the motor delivers 7.2 Nm of continuous torque at standstill, allowing stable holding force under continuous control. The motor has a nominal speed of 4000 rpm, giving fast response for medium-inertia applications without requiring a low-speed design. Position and velocity data are supplied by an integrated multi-turn absolute encoder, so the connected drive can retain position information through multiple revolutions.

A holding brake provides 6.5 Nm of static torque to keep the axis stationary after power is removed. The controller receives command-loop feedback through digital servo feedback (DSF), which supports accurate speed and position regulation during interpolation. The motor uses a plain shaft, making it suitable for clamping couplings and other keyless drive elements. The rotor uses standard balancing, which helps reduce vibration as speed rises. This arrangement helps the motor run smoothly during acceleration, deceleration, and repeated indexing cycles.
