Product Description:

The MDD090B-N-040-N2M-110PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it converts commanded three-phase current into precise mechanical motion for positioning axes, pick-and-place gantries, and other automated equipment. Integrated position feedback and torque generation let the motor operate as a direct actuator in closed-loop industrial automation, where accurate response to changing load conditions is important for repeatable motion.

At standstill, it delivers a continuous torque of 7.2 Nm, enabling static load holding without overheating during normal operation. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm for typical feed-axis duty. Accurate mechanical alignment is assisted by a centering diameter of 110 mm, which matches common flange cutouts and helps the motor seat correctly during installation. The 090 frame size gives a useful balance between inertia and torque for mid-range servo axes. Position feedback is supplied by an integrated multi-turn absolute encoder, which reports shaft position across multiple revolutions to the controller. Power is transmitted through a shaft with a keyway, allowing reliable torque transfer to couplings or pulleys. Standard dynamic balancing helps reduce vibration while the motor runs at speed.

A blocking brake rated at 6.5 Nm secures the shaft when power is removed, which is useful on vertical axes or other applications that must resist backdriving. Power and feedback conductors exit on the right side through a sealed connector interface, helping keep cable routing orderly in compact machine layouts. The output end includes a shaft seal to limit the ingress of oil or dust during operation. The motor receives position signals through digital servo feedback, which is compatible with Indramat drive controllers. The housing uses the standard enclosure style, the shaft end does not include a side B extension, and the length code B configuration keeps the overall depth compact for installations with limited space.
