Product Description:

The MDD090B-N-020-N2L-130GR2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded electrical input into accurate rotary motion for axis control in automated machinery. The motor uses a standard housing and standard balancing, giving it a general-purpose configuration that fits many industrial installations. It is commonly used on feed axes, indexing units, and other machine functions that require repeatable servo response.

In operation, the motor provides a continuous stall torque of 7.2 Nm, which allows it to hold a load steadily while the shaft is at standstill. Its nominal speed is 2000 rpm, making it suitable for medium-speed servo applications that need stable motion and responsive control. Mechanical alignment is supported by a 130 mm centering diameter that fits common flange connections. Power and feedback conductors leave from the right side, which can simplify cable routing when the motor is mounted beside other components. The motor also carries size code 090, placing it within the corresponding frame range of this series. The single-connector arrangement keeps the connection point compact and reduces the number of separate cable entries.

Position information is returned through digital servo feedback, allowing the drive to monitor rotor movement in real time for closed-loop control. The motor has length code B, which corresponds to the stack length used for this frame and supports sustained current operation within the intended thermal range. An integrated blocking brake provides 11.0 Nm of holding torque, so suspended or vertical loads can remain secured when power is removed. The output uses a plain shaft with a shaft seal, and the motor does not include a second shaft end on side B. That layout reduces overhang at the rear of the motor and supports direct coupling at the drive end.
