Product Description:

The MDD112D-F-040-N2L-130GB0 is a synchronous servo motor developed by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for tight integration with digital drive controllers, the unit converts commanded current into precise rotational movement for positioning tables, robotic joints, and spindle functions in automated production lines. Its frame size 112 and D-length stack provide a compact footprint with elevated torque capability, and the housing is prepared for liquid cooling so that thermal limits can be maintained during high-cycle operation under demanding duty.

A centering pilot of 130 mm ensures accurate alignment to host machinery and minimizes radial runout. At standstill, the motor can sustain a continuous torque of 38.0 Nm, allowing heavy loads to remain locked in position while drive current is regulated. Once energized, the rotor can reach a nominal speed of 4000 rpm, matching high-speed processing requirements without entering field-weakening ranges. Power and feedback conductors exit on side B, and a keyed connector simplifies plug-in installation inside a cabinet or cable track. Closed-loop control is supported by digital servo feedback (DSF), which transmits absolute position data with the resolution needed for precise path control in automated motion systems.

The housing is prepared for liquid cooling, allowing coolant plates to remove stator heat and keep winding temperatures stable during prolonged duty cycles. A plain shaft with a factory-fitted shaft seal helps prevent lubricant migration while still supporting couplings, pulleys, or direct-drive hubs. With a frame designation of 112, the motor uses the standard balancing quality of the series, operates without a blocking brake to reduce rotating mass, and omits a secondary shaft on the non-drive side to keep the overall length shorter.
