Product Description:

The MDD090C-N-040-N2M-110GB1 is a servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Engineered for use with digital drive controllers, it converts drive output current into controlled rotary motion for position and speed control in automated assembly stations, pick-and-place gantries, and light machining centers. Permanent magnets on the rotor and an internal feedback channel let the drive synchronize electromagnetic torque with commanded motion profiles. This arrangement helps the axis follow reference values with low tracking error during repeated starts, stops, and reversals.

This motor generates a continuous standstill torque of 10.4 Nm, giving machine axes enough holding force at zero speed without exceeding thermal limits. During dynamic cycles, it can operate at a nominal speed of 4000 rpm, matching high-speed requirements in short-stroke applications. A blocking brake is included, and its static capacity is 6.5 Nm, permitting secure load retention when power is removed. Mechanical integration is simplified by the centering diameter of 110 mm, which aligns the stator housing inside standard mounting bores, and a dedicated shaft seal protects the bearing set against coolant splash and fine dust. The motor uses standard balancing and a standard housing, has length code C and size code 090, and carries a plain shaft that transmits torque without key backlash.

Power and feedback connections enter on side B through a keyed connector, keeping cable routing clear of the driven load. Rotor position is resolved by an integrated multi-turn absolute encoder, while the drive receives position data as digital servo feedback (DSF) to close its control loops. A standard shaft end is provided only on the drive side, and the blocking brake is factory mounted so no external clamping unit is required.
