Product Description:

The MDD071B-N-040-N2L-095GA0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is built for use with digital drive controllers and converts commanded current into precise rotary motion for positioning, indexing, and speed-controlled machine functions. This motor is suited for automated machinery, packaging lines, and handling modules where accurate response and repeatable motion are required. Its layout also supports integration into cabinet-based or decentralized drive systems without adding unnecessary complexity to the axis design.

Its continuous torque at standstill is 4.4 Nm, which allows the rotor to hold a load during dwell periods without excessive heating. With rated electrical input, the motor reaches a nominal speed of 4000 rpm, making it suitable for mid-range servo axes that need steady velocity and responsive cycling. A centering diameter of 95 mm helps position the motor accurately on the machine mount, and the connections are arranged on side A so the power and feedback cables leave in one direction. Motion information is returned through digital servo feedback, allowing the drive to maintain closed-loop position and speed control. The motor uses size code 071 and is balanced to the standard quality grade to reduce residual vibration during operation.

The motor is supplied without a blocking brake, so parked loads must be held by external clamping or by continuous torque from the drive. A shaft seal protects the output area from coolant splash and dust ingress, and the output uses a plain shaft rather than a keyed or splined alternative. Electrical power and feedback are routed through a single machine-side connector, which keeps cable routing consolidated at the motor. The housing follows the standard enclosure style, and the shaft end does not include a second output on side B. Length code B identifies the body length used for this version of the motor.
