Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-020-N2M-110PL1 in its MDD Synchronous Motors series. The unit is a motor for digital drive controllers that converts precision current commands into tightly regulated shaft rotation for automated packaging stations, gantry axes, and mid-frame machine tools. Integrated feedback components and standard housing dimensions allow the motor to mount close to the load, minimizing couplings and improving dynamic positioning accuracy in production cells. Its design also suits closed-loop motion tasks that require repeatable acceleration, deceleration, and stable positioning during continuous machine operation.

The motor reaches a nominal speed of 2000 rpm, matching drive outputs that operate on 50/60 Hz field-oriented control. A continuous torque at standstill of 10.4 Nm supports static holding or low-speed feed moves without overheating, while standard balancing keeps vibration within IEC class N limits. The centering diameter is 110 mm, providing a repeatable pilot fit on machine plates. Power and feedback conductors exit on the left side through a sealed connector, simplifying cable runs in cabinets where right-hand clearance is tight. The C-length frame and size 090 cross-section provide the iron volume needed for thermal dissipation, and the standard housing variant avoids additional airflow devices. This layout also helps maintain clear cable routing around guards, slides, and neighboring machine structures.

Position data is measured by an integrated multi-turn absolute encoder and transmitted as digital servo feedback, so the control loop receives position information without relying on incremental-only tracking. A blocking brake rated at 6.5 Nm secures vertical or suspended loads when the drive is disabled, and a shaft seal helps limit lubricant escape during washdown cleaning. The single-ended shaft uses a keyway for positive torque transmission, and the absence of a side B shaft keeps the overall length compact. Because the encoder retains absolute position information across multiple revolutions, the axis can return to operation after a power interruption without a separate reference run. Standard balancing and the C motor length support predictable motion response during repeated starts, stops, and direction changes.
