Product Description:

The MDD090A-N-040-N2L-130PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor designed for digital drive controllers, it converts commanded current into rotary motion for positioning and velocity control in automated machinery and handling systems. Its housing, balancing, and shaft end follow the standard configuration for this series, and the unit includes a blocking brake so that loads can be secured when drive power is removed. This arrangement supports controlled axis motion during normal operation and secure holding when motion must stop.

The mechanical interface uses a 130 mm centering diameter that aligns the motor flange with gearboxes or machine frames. Power and feedback conductors exit on the right-hand side, a layout identified as the Right connection direction, and they terminate through a keyed connector that supports secure cable attachment. Under continuous stall conditions, the motor delivers 3.7 Nm of torque while staying within its thermal limits, and when energized it can reach a nominal speed of 4000 rpm. This operating range supports both low-speed holding duty and higher-speed axis movement in packaging, transfer, and indexing applications.

The blocking brake provides up to 6.5 Nm of static torque, which helps prevent axis drift on vertical or high-inertia loads when the controller is disabled. A shaft with a keyway supports positive torque transmission to pulleys or couplings, and an integrated shaft seal helps reduce oil or coolant ingress along the journal. Position feedback is generated by the motor’s internal digital servo feedback, allowing closed-loop operation with high resolution and stable speed regulation. The frame identified by size code 090 offers a compact motor envelope that fits machine layouts where installation space and responsive motion are both important.
