Product Description:

The MDD090B-N-040-N2M-110PA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a motor for digital drive controllers, it provides rotational power and position data to servo amplifiers in automated machinery, enabling closed-loop motion control for packaging, printing, and material-handling axes. It is suited for applications that require coordinated speed changes, repeatable positioning, and stable response during frequent start-stop cycles. The motor can be paired with servo systems that need fast response without adding external feedback hardware. The shaft end on side B is omitted to keep the overall length shorter where installation space is limited.

This model delivers a continuous standstill torque of 7.2 Nm, giving drives predictable low-speed force for holding or slowly indexing loads. Under rated excitation it reaches a nominal speed of 4000 rpm, which suits fast cycle tasks on compact servo axes. Mechanical alignment to gearboxes or fixtures is simplified by a centering diameter of 110 mm. Power and feedback lines exit on Side A, and the factory-installed Connector style allows direct cable attachment at the motor. This cable orientation can help keep bends controlled when the machine layout favors one-sided routing. Standard housing and balancing help the motor run smoothly during repeated acceleration and deceleration. Motor length code B and size 090 indicate the stator stack and frame diameter used for this frame.

An Integrated multiturn absolute encoder returns shaft position across multiple revolutions, and its signals are formatted as Digital servo feedback for direct input to compatible controller interfaces. Because the feedback device is built into the motor, the drive can receive position information without a separate external measuring unit. Multi-turn position retention helps the axis recover its mechanical reference after normal power cycling. The unit is supplied without a blocking brake, so external clamping or drive torque must secure vertical loads during power-off states. A sealed keyway shaft transmits torque positively, while the installed shaft seal helps protect the bearing area from contamination and lubricant migration. This shaft arrangement is suitable for couplings and transmission elements that require a fixed mechanical connection.
