Product Description:

The MDD090B-N-040-N2M-110GA1 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It supplies closed-loop rotary motion to digital drive controllers, giving machine tools, handling axes, and packaging stations accurate velocity and position control under industrial automation conditions. Its operating concept supports repeatable axis movement, so programmed motion profiles can be followed with stable response during indexing, feed motion, and positioning tasks.

This motor delivers a continuous standstill torque of 7.2 Nm, meaning it can hold that load thermally indefinitely without exceeding its rated temperature. At its nominal speed of 4000 rpm, the rotor reaches the intended operating range for sustained production use. A centering diameter of 110 mm aligns the flange precisely to the machine frame so radial runout remains minimal. Power and feedback cabling exits on Side A, which helps keep cable routing consistent where connections are grouped on one face of the motor. The housing accepts a keyed Connector, so the electrical interface remains orderly and secure during installation and regular operation.

A blocking brake supplies 6.5 Nm of holding torque to secure vertical loads whenever the drive is disabled. Position data is generated by an integrated multiturn absolute encoder, so the controller receives true shaft angle information immediately after power-up. Command loops are closed through digital servo feedback, allowing precise current and velocity regulation during changing load conditions. The output uses a plain shaft with a shaft seal, which helps limit the entry of contaminants and supports dependable coupling to the driven mechanism. Standard dynamic balancing helps the motor run smoothly, and the standard housing finish suits typical industrial mounting environments.
