Product Description:

The MDD065B-N-060-N2M-095PR1 synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is supplied as a compact drive element for digital drive controllers, translating command signals into precise rotational motion for positioning, conveying, and cyclical machining tasks in automated installations. The motor is suited for closed-loop axes that need repeatable motion in transfer units, feeders, and light machining stations while still fitting into a compact mounting space.

This model carries a nominal speed rating of 6000 rpm, meaning the rotor can run at that speed under rated voltage before field weakening is needed. At standstill, it can deliver 1.5 Nm of continuous torque, which supports light clamping or feed tasks while maintaining thermal equilibrium. Mechanical fit is aided by a 95 mm centering diameter that aligns the frame to standard machine flanges. Power and feedback conductors exit on the right side, and a single connector simplifies plug-in wiring. The rotor is factory balanced to a standard quality grade to help limit vibration, and the size code 065 with length code B indicates the stator stack used for this motor.

A blocking brake is integrated, and it supplies 3.0 Nm of static holding torque to secure vertical axes when the drive is de-energized. Position data are captured by an integrated multi-turn absolute encoder, which reports shaft angle across multiple revolutions to the controller without battery support. Velocity loops close through digital servo feedback (DSF) to maintain accuracy during rapid reversals. The output shaft uses a keyway shaft together with a shaft seal to help prevent lubricant migration into the motor interior. The absence of a side-B shaft end simplifies coupling to gearboxes or pulleys on the drive side only.
