Product Description:

Bosch Rexroth Indramat builds the MDD090B-N-020-N2M-110GL2 as part of the MDD Synchronous Motors series. The unit is a closed-loop servo motor intended for digital drive controllers in automated machinery, where it converts commanded current into precise rotary motion for axes that require repeatable positioning and speed control. The housing is supplied in the standard style, and the interface uses a sealed connector that mates quickly during installation. This type of motor is suited to machine axes that require repeatable starts, stops, and synchronized motion with the rest of the system.

The motor delivers a continuous standstill torque of 7.2 Nm, providing constant holding force when the shaft is energized but idle. Under rated electrical frequency, it reaches a nominal speed of 2000 rpm, which establishes the base velocity for coordinated multi-axis moves. A blocking brake is integrated and can clamp up to 11.0 Nm when power is removed, preventing load back-drive on vertical or suspended axes. Rotor balance is set to the standard grade to minimize vibration, and the centering diameter measures 110 mm for alignment with compatible machine flanges. Power and feedback conductors exit on the left side, simplifying cabinet layout when multiple motors share a common raceway. The motor also has size 090, length code B, a factory-installed shaft seal, and a standard shaft end without a side-B extension.

An integrated multi-turn absolute encoder tracks position over multiple revolutions without a battery, and the drive reads the signal through digital servo feedback to close the velocity and position loops. The output side uses a plain shaft that accepts keyed or clamped couplings. Electrical connection is made through a DIN-style connector rated for the motor's peak current. This feedback arrangement supports stable speed regulation and accurate positioning over the full operating cycle.
