Product Description:

The MDD090B-N-040-N2M-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary motion for mid-range axes in automated machinery. The unit uses the 090 frame size with the B length code, giving it a compact profile suited for dense machine layouts. A standard housing and standard dynamic balancing help keep vibration controlled during positioning, indexing, and speed-regulated operation.

At standstill, the rotor can deliver a continuous torque of 7.2 Nm, indicating the sustained output available for static holding or low-speed positioning without overheating. During normal operation, the motor reaches a nominal speed of 4000 rpm, which suits applications that require fast cycle times and responsive control. A blocking brake is fitted, and its holding capability is 6.5 Nm when the axis must remain in place after power is removed. The 130 mm centering pilot supports concentric mounting for accurate flange alignment. Power and feedback are routed through a single connector interface, which keeps external cabling straightforward and reduces the number of separate connections.

Position feedback is supplied by an integrated multi-turn absolute encoder, and the signal path uses digital servo feedback (DSF) for stable position and speed information across the operating range. Mechanical power is transmitted through a plain shaft, and a shaft seal helps protect the bearing area from contamination. All electrical terminations exit on the right side of the housing, which can simplify cable routing when several axes are mounted next to one another. The shaft is present only on the drive end, so the standard configuration does not include a side B shaft extension. This layout leaves the rear end of the motor closed and keeps the overall package simple for direct installation.
