Product Description:

The MDD071B-N-060-N2T-095PA1 is a synchronous servo motor from Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed on positioning axes, indexers, and ancillary tooling where fast electrical-to-mechanical conversion is required for repeatable motion in automated manufacturing cells. The unit works with compatible drive electronics for closed-loop speed and torque regulation. Because it is intended for direct use with digital controllers, command changes can be translated into shaft motion with minimal delay.

The motor reaches a nominal speed of 6000 rpm, enabling high cycle rates in light to medium-load applications. During continuous standstill, it can develop 4.4 Nm of electromagnetic torque, which indicates how much static load the axis can hold while energized. An integrated blocking brake supplies an additional mechanical holding capability of 3.0 Nm, preventing back-driving when power is removed. Accurate centering on machine frames is provided by a 95 mm pilot diameter, while the power and feedback plugs are oriented on Side A and use a keyed connector interface for secure cable attachment. The brake also helps hold vertical or unbalanced loads when electrical power is not available.

An integrated multi-turn absolute encoder feeds rotor position data to the drive through digital servo feedback, allowing position information to remain available after downtime. Dynamic balance is set to the standard grade, and the aluminum housing supports even heat dissipation without extra cooling fixtures. The rotor uses a keyway shaft, and a shaft seal is fitted to limit lubricant migration into the motor cavity. Size code 071 and length code B correspond to the stator stack dimensions, while the shaft end is supplied only on the drive side so there is no unused extension on side B. This arrangement supports precise axis synchronization when multiple motion commands must be coordinated inside the same machine.
