Product Description:
The MDD112C-N-030-N2L-130GA2 is an AC synchronous motor manufactured by Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts DC bus energy from an inverter into rotary motion for positioning and velocity control tasks in industrial automation. The unit belongs to motor size 112 and uses the C length code, providing a torque-to-inertia profile that suits medium-inertia axes in packaging machinery, material-handling portals, and similar installations.
At standstill, the rotor can deliver a continuous torque of 28.0 Nm, so thermal saturation is avoided during static load conditions. Under rated excitation, it reaches a nominal mechanical speed of 3000 rpm, matching common 50/60 Hz inverter outputs for synchronous operation. Assembly is centered with a 130 mm pilot diameter, ensuring concentric alignment with gearboxes or flanges. Power and feedback connections are on Side A, simplifying cable routing inside control cabinets when the motor is mounted with the shaft pointing forward. A keyed connector interface is used instead of a fixed cable, allowing quick exchange without re-terminating leads. Standard balancing and housing limit vibration and suit both horizontal and vertical installation orientations.
For dynamic braking and vertical axes, the motor is supplied with a blocking brake that develops 40.0 Nm of holding torque and locks the rotor when the controller removes excitation. Position feedback is provided through digital servo feedback, giving absolute position information for high-resolution closed-loop control. The drivetrain end uses a plain shaft, eliminating keys that could introduce backlash, and sealing is maintained by a fitted shaft seal to keep lubrication in and contaminants out.
