MDD065B-N-060-N2M-095PR1
The MDD065B-N-060-N2M-095PR1 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. In automated systems it serves as a compact rotary actuator, converting commanded current from a digital drive controller into accurate shaft motion for indexing tables, pick-and-place heads, and light machining axes. Its mechanical footprint and feedback interface are tailored for multi-axis machinery where precise repeatability and high cycle rates are required. That operating profile is useful on compact axes that alternate rapidly between motion and dwell without losing commanded position.
This size-065 motor with length code B uses standard rotor balancing and a standard housing, providing stable operation without additional counterweights. The flange includes a centering diameter of 95 mm to maintain concentricity with gearboxes or couplings. A blocking brake produces 3.0 Nm of holding torque to secure vertical loads when power is removed, while the stator generates 1.5 Nm of continuous torque at standstill for closed-loop positioning. Motion feedback comes from an integrated multi-turn absolute encoder, and the position data travels over digital servo feedback lines to the controller. This feedback arrangement lets the drive monitor rotor position continuously during startup, speed changes, and holding operation.
Cabling exits on the right side through a molded connector that combines power, brake, and signal contacts, simplifying panel layout and reducing cable congestion near the motor body. Under rated excitation, the rotor reaches a nominal speed of 6000 rpm, allowing fast traverse moves before settling into fine positioning. Mechanical output is delivered through a keyway shaft that matches standard hub components, and ingress of dust or coolant is restricted because the front end is equipped with a shaft seal. The absence of a secondary shaft on side B reduces overall length and helps the motor fit into tight enclosures.
