Product Description:

The MDD065B-N-040-N2M-095GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, the unit converts commanded current into proportional torque for positioning or velocity loops in automated machinery. Its synchronous design supports precise speed regulation and repeatable axis motion in automated systems.

The mounting face includes a centering recess of 95 mm, providing a fixed reference for concentric alignment with gearboxes or bell housings. Continuous stall torque is rated at 1.5 Nm, which is the torque the motor can deliver continuously without exceeding thermal limits at nominal cooling air temperature. Rated speed reaches 4000 rpm, allowing direct drive of lightweight loads without intermediate gearing. Electrical terminations are routed toward the rear because the power and feedback plugs are on side B of the frame. The interface is a sealed connector that supports quick connection of pre-assembled cables.

An electromagnetic brake provides 3.0 Nm of holding torque so vertical axes remain fixed when the drive is disabled. Position sensing is derived from an integrated multi-turn absolute encoder, and it retains shaft position through multiple revolutions after power loss. Signals from the encoder are transmitted as digital servo feedback (DSF), enabling noise-resistant differential communication with the drive. A shaft seal is fitted to help block lubricant migration into the motor interior and support the IP65 enclosure concept. The plain output shaft follows DIN tolerances and is supplied without a secondary shaft on the rear side, which helps reduce rotor inertia for faster acceleration. Motor length code B, frame size 065, standard housing, and standard dynamic balancing complete the mechanical profile, while space remains available for external blower options if higher continuous output is required.
