Product Description:

The MDD090A-N-030-N2M-110PA0 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded electrical input into controlled rotary motion for indexing tables, pick-and-place axes, and similar automation tasks that require repeatable speed and position. Its synchronous design supports stable motion control during frequent starts, stops, and direction changes. The motor is suitable for equipment that must maintain accurate axis behavior through repeated operating cycles.

This model delivers a continuous standstill torque of 3.7 Nm, which provides moderate holding force during static positioning. Under rated excitation, it reaches a nominal speed of 3000 rpm, supporting fast cycle rates in compact machinery. Accurate mechanical alignment is supported by a centering diameter of 110 mm, which mates with standardized mounting surfaces. Power and feedback conductors exit on side A, which can simplify cable routing when cabinet entries are grouped on one face of the motor. A removable connector carries both power and signal conductors, allowing the connection point to be serviced without opening the stator housing. Standard dynamic balancing helps reduce vibration, and the keyway shaft transfers torque directly to pulleys or couplings.

Closed-loop control is maintained through digital servo feedback (DSF), and position data is provided by an integrated multiturn absolute encoder. This arrangement allows the drive to retain position information after power cycles, so a homing routine is not required at startup. The motor is supplied with a shaft seal, which helps limit contaminant ingress at the rotating interface. It is also supplied without a blocking brake, so load holding during power loss must be handled by external clamping or drive torque. The single-ended shaft and the short A-length housing keep the motor compact and favor lower inertia in applications that prioritize fast response over higher torque density.
