Product Description:

The MDD071B-N-060-N2T-095GR0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts command currents into precise shaft motion for positioning and velocity tasks on automated machinery, packaging lines, and material-handling axes. Its compact frame and B-length make it a practical choice where high rotational speed is needed from a small envelope without adding excess mass to the moving structure. That combination is useful on axes where rapid acceleration must be balanced with accurate position holding during repeated cycles.

The centering pilot measures 95 mm, providing a repeatable location surface so the motor can be mounted without radial misalignment relative to the driven mechanics. At standstill, it produces 4.4 Nm of continuous torque, which allows it to hold load steadily while maintaining thermal equilibrium. When accelerated to its nominal velocity of 6000 rpm, the rotor supports dynamic motion suited to indexing, spindle, or winding duties. Position feedback comes from an integrated multi-turn absolute encoder, allowing the controller to track angular location across multiple revolutions after power cycles. This feedback arrangement gives the connected controller immediate position information after restart, which helps restore axis reference quickly. Power and signal connectors exit on the right side of the stator housing, which simplifies routing when the cable chain approaches from that direction.

The drive evaluates rotor angle through digital servo feedback, which helps maintain consistent commutation and stable low-speed control over temperature changes. Because the motor is supplied without a blocking brake, any holding function must be provided by the drive or an external brake module. Mechanical output is transferred through a plain shaft that lacks a key, favoring couplings that clamp directly to the journal and reducing the need for keyed hub alignment. A dedicated shaft seal sits behind the front bearing to limit ingress of coolant splash or fine dust in machine tools and automated transfer stations. This shaft arrangement is commonly paired with friction-locking hubs, while the seal helps protect the front bearing area during splash-prone or dusty operation.
