Product Description:
The MDD115C-N-020-N2L-130GA2 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It interfaces with digital drive controllers to convert electrical energy into precise rotational motion for automated positioning, indexing, and speed-regulated transport duties on production machinery. Its standard housing, connector-based cabling, and mid-range physical envelope allow installation inside enclosed axes where contamination control is essential. The integrated encoder channel links directly to the controller so motion loops remain synchronized in real time.
The motor delivers a continuous standstill torque of 47.0 Nm, meaning it can hold or slowly drive a load at zero speed without exceeding its thermal limit. During standard operation, the rotor reaches a nominal speed of 2000 rpm, a speed chosen to balance dynamic response with bearing life in medium-inertia applications. Position and velocity data are returned through digital servo feedback, enabling the drive to close tight loops without separate resolvers or tachogenerators. A centering shoulder diameter of 130 mm provides the register fit on the machine faceplate and keeps the stator concentric with the driven shaft. Power and signal connectors are routed on side A, simplifying cable management when multiple axes are aligned in parallel rows.
An integrated blocking brake provides a holding capacity of 60.0 Nm, preventing back-driving of vertical or overhung loads when the controller is disabled. The output interface uses a plain shaft, so torque is transferred through couplings rather than keyed joints, minimizing stress concentrations. Frame designation 115 indicates the stator outside dimension and matches accessories within the MDD family. There is a shaft seal at the output end, which restricts coolant or lubricant ingress into the bearing cavity during washdown or oil-mist service. Standard dynamic balancing and a C-length stator complete the mechanical package for this motor configuration.
