Product Description:

The MDD112D-N-020-N2M-130GA0 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts the pulse-width-modulated output of Rexroth inverter stages into tightly regulated rotary motion for industrial automation axes. A standard housing and factory balancing help keep vibration within normal operating limits, and the connector-based power and feedback interface simplifies wiring when the unit is installed on gantries, rotary tables, or packaging machinery. Its synchronous design supports accurate commutation and stable low-speed operation in positioning, indexing, and transfer applications.

At standstill, it can supply 38.0 Nm continuously, allowing it to support static loads without overheating. During motion, the rotor reaches a nominal speed of 2000 rpm, which fits many feed-axis applications in automated equipment. A centering shoulder of 130 mm positions the flange accurately against gearboxes or frame bores, and the power and feedback conductors exit on side A. The output uses a plain shaft, so torque is transmitted through friction-locked clamping hubs rather than keys. The flange fit also helps preserve alignment between the motor and the driven load during installation.

Position is captured by an integrated multiturn absolute encoder, and rotor data returns to the drive through digital servo feedback for high-resolution velocity and position control. A shaft seal helps limit lubricant migration into the bearing zone, and the motor is supplied without a blocking brake, so an external holding device is needed on vertical axes. The frame code of 112 identifies the motor size used for this housing. This feedback arrangement allows the controller to correct motion errors during changing load conditions and maintain stable axis response. Absolute position data remains available after normal power cycling, which supports quick return to controlled motion.
