Product Description:
The MDD112C-N-015-N2M-180GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it fits closed-loop axes where position and torque are regulated by electronic drives. The unit is supplied without a blocking brake, so stopping torque must come from the drive or an external mechanism. A standard housing and standard balancing allow direct mounting to machine frames with minimal vibration. This layout suits positioning and feed applications that require stable servo response during frequent starts, stops, and load changes.
The motor body provides a centering land of 180 mm, ensuring concentric alignment with coupling flanges and reducing radial runout in heavy-duty assemblies. At standstill, the windings can deliver 28.0 Nm of continuous torque, giving sufficient holding force for indexing tables and feed drives that remain energized. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, which suits moderate-speed applications that demand high torque at low frequencies. All power and feedback conductors exit on the rear because the connection hardware is fixed on Side B, simplifying cable routing inside deep cabinets. This rear connection arrangement can also help keep wiring clear of couplings and other moving machine elements. Positional data travels through Digital servo feedback (DSF), permitting high-resolution closed-loop control without additional encoders.
The motor has a size code of 112 and a length designation of C, giving it a medium frame depth for medium-inertia tasks. Absolute position is captured internally by an integrated multiturn absolute encoder, so the axis can retain position information after a power interruption. A factory-installed shaft seal guards the plain output shaft against oil or coolant ingress, and the shaft is supplied without a second end on the rear face. This single-sided arrangement leaves the rear area available for the connector interface and feedback hardware. Electrical termination uses a circular connector, and the plain shaft can work with keyed couplings or clamp hubs as required by the driven load.
