Product Description:

The MDD090A-N-040-N2M-110PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, this motor supplies controlled torque and velocity so that automated machinery can index, follow curves, or hold position under closed-loop regulation on assembly lines, packaging stations, and material-handling axes. It is suitable for transfer systems, rotary tables, and compact handling axes that need repeatable motion during frequent start-stop cycles and accurate stopping under changing load conditions.

The unit reaches a nominal shaft speed of 4000 rpm, allowing high cycle rates when the drive applies the rated frequency. At standstill, it can deliver a continuous torque of 3.7 Nm, which is the continuous thermal limit for static load support without external cooling. An integrated blocking brake on the non-drive end supplies 6.5 Nm of holding torque so vertical or suspended loads remain fixed after power is removed. Mechanical centering during mounting is aided by a flange with a 110 mm centering diameter, and the shaft has a keyway for positive torque transmission to couplings or pulleys.

Cabling exits on the left side because the power and feedback connectors are oriented on that side of the housing, which simplifies routing in cabinets laid out for lateral service access. Rotor position is monitored by an integrated multi-turn absolute encoder, and its signals are converted to drive-friendly data through digital servo feedback. This feedback arrangement supports precise commutation and position tracking after power-up. The motor uses length code A, which is the shortest frame in the 090 size class and helps keep inertia low for rapid acceleration. Standard dynamic balancing minimizes vibration, while a shaft seal blocks dust or coolant ingress and the molded connector interface allows cable changes without rewiring.
