Product Description:

The MDD090B-N-020-N2L-130PR2 is a synchronous AC servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise mechanical motion for positioning, speed, and torque control in automated machinery. The motor works with Rexroth drive systems on assembly lines, packaging equipment, and material-handling axes where regulated rotary motion is required. This arrangement suits applications that need repeatable starts, stops, and stable speed control during continuous production cycles.

It mounts against a machine register with a centering diameter of 130 mm, and the rotor is dynamically balanced to the standard grade used for the series. Power and feedback conductors exit on the right side through a single connector block, which helps simplify cable routing in compact cabinets and enclosed machine spaces. Under continuous stall conditions, the motor can deliver 7.2 Nm of torque without exceeding rated temperature, and it maintains closed-loop velocity up to 2000 rpm when driven by a matched inverter. Position and speed signals are returned through digital servo feedback (DSF), so the controller can regulate motion without an external encoder and can monitor rotor movement directly through the integrated feedback path.

A mechanical holding system is integrated, and the blocking brake clamps the shaft with 11.0 Nm of static torque to secure vertical or suspended loads when the drive is de-energized. An internal shaft seal is present to limit lubricant migration, and the single-ended output uses a keyway profile on the standard shaft end, with no secondary shaft on side B. The motor uses the 090 frame size and B length, which provide the thermal mass needed for its nominal ratings while keeping the housing size suitable for general machine integration. The standard housing and connectorized layout allow direct connection to digital drive controllers that use this motor type and wiring arrangement.
