Product Description:

The MDD071B-N-040-N2S-095PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use in digital drive systems, the unit converts commanded electrical power into rotational motion with closed-loop accuracy. In industrial automation cells, it typically drives positioning axes, indexing tables, or conveyor sections where rapid speed changes and precise torque delivery are required. Its electromagnetic construction works with compatible Rexroth drive controllers to keep velocity response stable under changing load conditions.

Mechanical dimensions begin with a centering pilot of 95 mm, which allows the flange to seat concentrically on machine frames. The motor has a continuous standstill torque of 4.4 Nm, which supports holding force and low-speed process loads while temperature remains within operating limits. Dynamic operation reaches a nominal speed of 4000 rpm, making it suitable for high-frequency motion profiles commanded by modern inverters. Position data are transmitted through Digital servo feedback, so movement is monitored in real time by the connected drive. The motor is supplied without a blocking brake, so holding force must be provided by the drive or by external machine mechanics. A right-angle connector interface, a standard housing, standard rotor balancing, motor length code B, and a single-ended shaft complete the physical configuration.

Power and feedback plugs exit to the Right, which can simplify cable routing in compact machine spaces. A factory-installed shaft seal helps block coolant or lubricant ingress along the output journal, while the ground keyway provides secure torque transfer to couplings or pulleys. The frame size is 071, placing the motor in a mid-range format suitable for general-purpose servo axes. This layout supports compact mounting arrangements where secure shaft coupling and protected cable exits are important.
