Product Description:

The MDD065B-N-040-N2L-095GR1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact permanent-magnet servo unit. It is intended for closed-loop positioning and speed control in industrial automation, where pairing with a digital drive controller allows deterministic motion profiles for conveyors, pick-and-place axes, and other electromechanical loads.

This motor reaches a nominal speed of 4000 rpm, enabling high cycle rates without mechanical gear multiplication. A continuous standstill torque of 1.5 Nm provides holding capability for moderate static loads while the windings remain within thermal limits. The centering diameter of 95 mm provides the pilot fit that keeps the stator concentric with the driven machine frame, and the rotor is assembled with standard dynamic balancing to minimize residual vibration at full speed. Power and feedback conductors exit on the right side through a single industrial connector, simplifying cable routing inside compact enclosures. Position data are returned via digital servo feedback, so the associated drive can apply corrective current within each control cycle for consistent speed and torque regulation under changing inertia.

Additional mechanical features secure the axis when power is removed. An integrated blocking brake delivers 3.0 Nm of static torque to prevent back-driving on vertical or biased loads, and the rotor interface is a plain shaft sealed by a low-friction lip to keep lubricant and contaminants isolated. The unit follows size code 065 with length code B, resulting in a standard housing that fits the MDD mounting footprint while limiting mass and inertia. A shaft end is provided only on the drive side, eliminating the need for a side B extension, and the presence of a shaft seal supports IP-rated cabinet installations. Classified as a motor for digital drive controllers, the model aligns electrically and mechanically with Indramat converters that supply current-controlled three-phase excitation.
