Product Description:

The MDD090C-N-030-N2M-110PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and converts commanded current from the inverter into rotary motion for indexing tables, gantry axes, and similar automation tasks. As a synchronous design, it supports repeatable speed regulation and accurate positioning during short-cycle machine operation. The unit follows the standard housing and balancing practice used for the series, allowing straightforward machine installation, while its shaft seal limits the ingress of coolant or dust at the coupling face.

The motor’s centering flange is machined to 110 mm, establishing the reference diameter that aligns the stator with the machine frame. Power and feedback conductors exit on side A, which keeps both cable groups on one end of the housing for cleaner routing. A front-mounted connector handles these terminations and keeps the interfaces accessible at the motor face. When energized, the electromagnetic package delivers a continuous standstill torque of 10.4 Nm, which suits mid-range positioning axes that must hold load without additional gearing. Rotor position is reported by an integrated multi-turn absolute encoder, allowing the drive to recover the exact angle after a power cycle and begin operation without a homing move.

A blocking brake generates 11.0 Nm of static torque, helping keep vertical loads from drifting when the drive is disabled. Control loops receive angle and velocity information through digital servo feedback, which supplies high-resolution data for closed-loop motion control. Under rated excitation, the rotor reaches 3000 rpm, a speed commonly used in packaging and material-handling equipment. A machined keyway on the shaft transfers torque to pulleys or couplings, while the single-ended shaft layout helps maintain rigid power transmission. The motor size 090 with length code C gives the unit a medium housing profile that fits many machine axes without requiring an oversized mounting space. This combination supports smooth indexing, quick reversals, and consistent stop positioning during repetitive cycles.
