Product Description:
The MDD090A-N-030-N2L-130GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. This compact unit interfaces directly with digital drive controllers to provide closed-loop rotary actuation in automated machinery. By integrating rotor position sensing and an internal stator optimized for high dynamic response, the motor translates electrical commands into precise shaft movement for indexing tables, packaging axes, and similar duties. The closed-loop arrangement helps the drive correct speed and position deviations as load conditions change. That behavior supports repeatable motion during frequent start-stop cycles in automated production equipment.
The motor’s continuous stall capability is 3.7 Nm, giving the drive enough holding torque to keep loads stationary during low-speed positioning without overheating. During normal operation, it reaches a rated mechanical speed of 3000 rpm, which matches common inverter frequencies for medium-inertia applications. Accurate mounting is supported by a centering shoulder of 130 mm, which aligns the housing concentrically with the machine frame. All power and feedback leads exit on Side A, simplifying cable routing when the motor is installed against a rear wall, and the round connector interface permits quick connection without opening a terminal box. This layout keeps the cable entry area concentrated on one end of the housing and supports orderly machine routing.
Control loop fidelity is enhanced by Digital servo feedback (DSF), which streams position data to the drive at high update rates. The 090 frame gives the motor a moderate footprint, while length code A keeps the housing short for machines with limited depth. Mechanical coupling uses a plain shaft with a shaft seal that blocks coolant splash and fine dust. The motor is supplied without a blocking brake, so any power-off holding function must be provided by an external clamp or by drive torque. It also uses standard dynamic balancing and a standard housing for normal industrial operation.
