Product Description:

The MDD112C-N-040-R2L-130GB0/S015 servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for use with digital drive controllers, it transforms commanded current into tightly regulated rotary motion for industrial automation tasks. The unit has a standard housing, a plain shaft, and a single-ended shaft design, so it couples directly to gearboxes or belt pulleys. This layout suits axes that need accurate motion while keeping the mechanical installation straightforward. It is suited to positioning axes, feed drives, and similar applications where stable response and repeatable motion are important during continuous operation.

At standstill the motor delivers 28.0 Nm of continuous torque, indicating the load it can hold indefinitely without exceeding thermal limits. When operated at its rated frequency, it reaches a nominal speed of 4000 rpm, enabling rapid positioning cycles. A centering shoulder measuring 130 mm forms the pilot fit between the motor flange and the machine frame, helping maintain consistent alignment during installation. Power and feedback leads exit on Side B, and the factory-installed connector combines phase and signal terminations to simplify cable routing and reduce the number of enclosure openings.

Dynamic behavior is supported by R balancing, which keeps residual vibration low at full speed. Integrated digital servo feedback returns position information for closed-loop control, and a positive-contact shaft seal protects the front bearing from spray and dust. The motor uses the 112 frame size with length code C, providing additional active iron without changing the mounting pilot. Because it is supplied without a blocking brake, the axis must rely on controlled motor torque or an external holding device when it is stopped. The sealed front end helps the motor operate reliably in machines exposed to airborne dust or light fluid splash.
