Product Description:

The MDD090A-N-040-N2M-110GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts command current into controlled rotary motion for positioning tooling, conveyor sections, and feed axes in automated equipment. Its compact frame and integrated feedback make it suitable for modular machines that require accurate velocity and torque control during repeated indexing and positioning tasks.

The motor has a centering pilot of 110 mm, which helps align the housing accurately against machine faces while the standard balancing grade helps limit vibration during high-speed rotation. At a nominal speed of 4000 rpm, the rotor can follow rapid command changes without excessive mechanical strain. During locked-shaft operation, it produces a continuous torque of 3.7 Nm, giving a useful reference for drive sizing and current limits. Power and feedback cabling exit on the right side, and a single connector combines phase leads and low-level signals in one interface. The housing and shaft end follow the standard MDD family versions, and the plain shaft accepts couplings or pulleys without a keyway.

To maintain position after motion stops, a blocking brake provides 6.5 Nm of static holding torque and engages automatically when power is removed. Rotor angle data is supplied by an integrated multi-turn absolute encoder, and the drive receives this information through digital servo feedback for closed-loop control during multi-cycle production runs. A fitted shaft seal helps keep oil and dust out of the bearing cavity, which supports reliable operation in typical industrial environments. This arrangement also helps protect the bearing area when the motor is installed near lubricated transmission components or general airborne contamination.
