Product Description:

The MDD090B-N-040-N2M-110PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies regulated torque for positioning and speed-control tasks in conveyors, gantries, and packaging equipment. Its electrical design pairs with compatible Indramat drive modules, allowing the unit to operate as a feedback-ready rotary axis without external sensors. This makes it suitable for closed-loop motion applications where the drive regulates torque, speed, and position from continuous feedback.

Its continuous torque at standstill is 7.2 Nm, which allows the shaft to hold static loads without thermal derating during rated operation. Under commanded motion, the rotor reaches a nominal speed of 4000 rpm, supporting fast cycles in automated machinery. A precision centering shoulder of 110 mm aligns the flange to gearboxes, and wiring exits the housing on the right side to suit parallel cabinet layouts. Position data is provided by an integrated multi-turn absolute encoder, so the controller can track shaft angle across multiple revolutions. The B-length housing within the 090 frame keeps the motor compact enough for medium-power axes while preserving stable operation during repeated starts and stops.

The output interface uses a shaft seal around the journal to help block dust and retain lubricant at the drive end. Torque is transmitted through a keyway, which allows rigid connection to pulleys, couplings, or gear wheels. Feedback signals are carried through digital servo feedback, supporting high-resolution commutation for the matched drive. The motor is supplied without a blocking brake, so static holding during shutdown must be provided by an external brake or another holding device. The standard housing uses surface cooling, and the single shaft-end layout leaves more room when the rear of the motor must sit close to guarding or nearby machine structure.
