Product Description:

Bosch Rexroth Indramat builds the MDD112C-N-020-N2M-180GB0 as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical control signals into rotary motion for positioning tables, pick-and-place axes, and other automated stations. The housing is arranged for direct installation on machine structures, and the motor uses standard dynamic balancing for stable operation at speed. Its 112 frame size with C length gives it a mid-range mechanical package suited to axes that need a balance of torque capacity and compact installation space.

At standstill, this model can supply a continuous torque of 28.0 Nm, allowing it to hold loads or perform low-speed indexing without excessive heat buildup. Under rated excitation, it reaches a nominal operating speed of 2000 rpm, which fits common servo applications that require steady base-speed performance. Precise alignment on the machine interface is achieved with a 180 mm centering diameter. Power is transmitted through a plain shaft, and rotor position data is returned to the drive through digital servo feedback for closed-loop control. A shaft seal helps limit lubricant migration into the stator cavity, while the standard housing supports cooling by natural convection.

Electrical and signal conductors exit the rear of the motor on Side B through a single connector, which helps simplify cable routing in compact machine layouts. The rotor angle is measured by an integrated multi-turn absolute encoder, so the drive retains position information across power cycles without requiring a homing routine at startup. For applications that already use external holding devices, the motor is delivered without a blocking brake, which reduces rotating mass and removes an internal brake assembly. The absence of a side-B shaft end also keeps the rear of the motor compact and leaves more clearance for cable management.
