Product Description:

The MDD065A-N-040-N2M-095GB1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotary motion to positioning axes and tooling spindles in automated machinery. The unit has motor size 065 with length code A, giving a compact form that fits space-limited machine layouts while retaining the mounting interfaces commonly used in this product line. This arrangement makes the motor suitable for equipment where accurate motion is required but available installation space is limited.

The motor delivers a continuous standstill torque of 0.8 Nm, and its windings support a nominal mechanical speed of 4000 rpm without exceeding thermal limits. An integrated blocking brake can hold up to 3.0 Nm when the drive is de-energized, which helps keep vertical or suspended loads from drifting at a stop. Electrical power and feedback cables are routed on Side B, and mounting accuracy is supported by a centering diameter of 95 mm. The rotor is balanced to the standard grade to reduce vibration at rated speed, and a molded circular connector provides a direct electrical connection without adding a separate terminal box.

An integrated multi-turn absolute encoder works with the drive’s digital servo feedback interface to provide position data for closed-loop control. This feedback arrangement allows the controller to monitor rotor position continuously during speed changes, indexing moves, and holding tasks. The plain shaft uses a shaft seal to help prevent lubricant escape and limit contaminant entry during operation. Its single-ended shaft arrangement leaves no rear shaft extension, which can simplify coupling selection and improve clearance where the motor is installed close to guards, plates, or adjacent axes.
