Product Description:

The MDD071C-N-040-N2S-095PB0 is a three-phase servo unit from Bosch Rexroth Indramat’s MDD Synchronous Motors series. As a dedicated motor for digital drive controllers, it supplies closed-loop rotary motion to positioning stages, packaging lines, and general factory automation. By integrating with the matching drive electronics, the unit translates commanded current into precise torque and speed for axes that demand consistent response.

The motor can deliver a continuous standstill torque of 6.6 Nm, allowing it to hold static loads without overheating. When rotation is required, its rated shaft speed reaches 4000 rpm, supporting fast cycle times on compact servo axes. Accurate centering against gearboxes or flanges is provided by a 95 mm pilot diameter. The motor operates without a blocking brake, so external measures must secure vertical loads during power-off conditions. Integrated Digital servo feedback (DSF) returns position data to the controller, enabling high-resolution velocity and torque loops. A standard housing encloses the stator, and the frame follows the 071 size classification, matching compact machines that still require moderate output. This model uses a single-ended shaft in its normal orientation and does not include a secondary rear shaft extension.

Electrical connections exit on side B through a sealed connector, simplifying cable routing inside compact cabinets. The companion signal plug uses the same interface style, which helps maintain consistent shielding practices. Internally, the rotor and fan use standard balancing to minimize vibration across the operating speed range. Axial length corresponds to code C, so the motor achieves its torque density without exceeding common installation depths. A keyway on the primary shaft enables rigid coupling, and a fitted shaft seal blocks coolant ingress.
