Product Description:

The MDD090C-N-020-N2M-110PB2 synchronous motor is built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It pairs with digital drive controllers to supply closed-loop rotary motion in automated production lines. A multiturn encoder is mounted on the rotor flank, allowing the controller to track absolute shaft position during startup and operation without external sensors and simplifying wiring in multi-axis assemblies.

The motor sustains 10.4 Nm of continuous standstill torque, so it can hold a load against gravity or process friction while stationary without overheating the windings. During rapid deceleration or power loss, the integrated blocking brake clamps the shaft with 11.0 Nm of torque, eliminating the need for an external brake module. Rated speed is 2000 rpm, which sets the velocity ceiling for linear or rotary actuators driven by the unit. Position data are returned through Digital servo feedback (DSF). The onboard sensor package is an Integrated multiturn absolute encoder, which records multiple revolutions for homing-free startup. All power, brake, and feedback conductors exit on the rear housing because the connection hardware is located on Side B, a layout that suits cabinets where cables drop downward from overhead carriers.

A centering pilot of 110 mm aligns the flange with gearboxes or bulkheads, keeping radial runout low when the keyed shaft engages the load. The shaft interface is a keyway type and is fitted with a shaft seal to block coolant splash or lubricant mist from migrating into the bearing set. Standard dynamic balancing minimizes residual vibration in high-speed duty, while the C length code provides additional stack height for higher torque density without changing the 090 frame size. Housing and connector choices remain standard for the MDD platform.
