Product Description:

The MDD090A-N-040-N2M-130PA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a motor for digital drive controllers that supplies closed-loop rotary motion to automated axes, allowing positioning and speed regulation in packaging lines, handling gantries, and machine tools. Its size 090 and length code A give it a compact form that fits densely packed multi-axis equipment without adding unnecessary installation depth. That layout suits production cells where several servo axes must be mounted close together while still leaving room for cable routing and coupling hardware.

This model uses a centering diameter of 130 mm, allowing the stator flange to align precisely with matching machine mounts. A continuous standstill torque of 3.7 Nm allows the motor to hold a steady load without exceeding its thermal limit. The rotor can reach a nominal speed of 4000 rpm, supporting fast cycle times where quick acceleration and deceleration are required. The rotor uses the factory's standard balancing grade, which helps limit vibration during operation. Power and feedback conductors exit on Side A, and the motor uses a connector interface instead of a fixed pigtail for straightforward cable attachment. This arrangement supports installations that route cables from one side of the machine frame to keep moving sections clear.

An integrated multiturn absolute encoder tracks shaft position over multiple revolutions, enabling homing-free startups and precise electronic gearing. Feedback signals are transmitted as digital servo feedback, which is compatible with Rexroth drive controllers that process high-resolution serial data. The unit is delivered without a blocking brake, so external holding is required if the load must remain in place when power is removed. A shaft seal limits lubricant migration and helps reduce particulate ingress. The keyway shaft end provides positive mechanical coupling to pulleys or couplings without relying only on friction. The sealed shaft end is useful where light contamination or lubricant exposure is present near the drive connection.
