Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-020-N2M-130GL2 in its MDD Synchronous Motors series. The unit is a brushless AC servo motor intended for digital drive controllers, where it converts commanded current into precise angular motion for positioning tables, gantry axes, and pick-and-place arms. In automated lines, this closed-loop behavior helps the axis follow programmed moves during acceleration, constant-speed travel, and stop positioning. It supports accurate velocity and torque execution across repeated production cycles. Its construction follows established mechanical and electrical interfaces for the series, allowing straightforward integration in multi-axis assemblies.

The motor has a centering diameter of 130 mm, a 090 frame designation, and a length code B that provide moderate thermal mass for mid-range duty cycles. This arrangement gives a practical balance of compact size and heat capacity for general motion tasks. Standard balancing keeps residual vibration within the limits expected for general-purpose mounting, and the housing shares common fastener patterns with other motors in the series. Electrical and signal connectors are mounted on the left side and use a keyed connector interface. Under continuous stall conditions, the rotor can deliver 7.2 Nm of torque, while commanded speed can reach 2000 rpm without derating. Position sensing is handled by an integrated multiturn absolute encoder, which supplies position data to the drive for closed-loop control.

Stopping and holding functions are built in, and a blocking brake supplies 11.0 Nm of static torque to secure loads when power is removed. This feature can help keep parked axes from drifting at standstill. The motor has a plain shaft, and a shaft seal helps retain lubrication and prevent dust entry at the output end. The design omits a side-B extension, which simplifies coupling to gearboxes or belt pulleys. Command and feedback wiring uses digital servo feedback (DSF), allowing the paired controller to read high-resolution motion data and adjust current in real time.
