Product Description:

The MDD090C-N-030-N2M-130PR2 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. As a motor for digital drive controllers, it supplies rotary motion that can be matched precisely to commanded position, velocity, or torque loops in automated machinery. Standard balancing and a standard housing allow direct installation in industrial frames, while the connector interface simplifies cable routing toward the right side of a cabinet or robot joint. Its feedback-equipped design supports repeatable axis control in indexing tables, feed systems, and similar automation tasks.

This motor maintains positional stability by developing 10.4 Nm of continuous torque at standstill, which allows it to hold a constant load without overheating during continuous duty. During normal operation, the rotor reaches a nominal speed of 3000 rpm, a synchronous velocity suited for medium-inertia axes on packaging lines or gantries. Precise mechanical alignment is aided by a centering diameter of 130 mm, so the pilot fits tightly into matching machine shoulders and helps minimize runout. Electrical and resolver terminations exit on the right side, which keeps service loops short when the motor is mounted on left-hand servo modules. Closed-loop regulation is executed through digital servo feedback (DSF), allowing the associated drive to sample position data with high resolution and correct deviation in real time.

A blocking brake supplies 11.0 Nm of holding torque so vertical or suspended loads remain fixed when power is removed. Position information is preserved even after rotation through multiple revolutions thanks to the Integrated multiturn absolute encoder, so the drive can recover axis position after a power cycle without a reference run. Torque is delivered through a keyed shaft, identified by the keyway construction, which supports positive mechanical locking of pulleys or couplings. The output also includes a shaft seal that helps limit fluid ingress along the journal surface and protects the bearing area from lubricants or coolants.
