Product Description:

The MDD071B-N-030-N5M-095PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. It converts controlled electrical power into precise rotary motion for tooling axes, pick-and-place heads, or conveying spindles used in industrial automation cells. An integrated multi-turn absolute encoder supplies exact rotor position data, while the digital servo feedback channel lets the drive read that data directly for high-resolution closed-loop control.

At standstill, the motor can deliver continuous torque of 4.4 Nm, which is the maximum load the shaft can sustain indefinitely without thermal overload. During normal operation, the rotor reaches a nominal speed of 3000 rpm, giving the controller a predictable operating point for matched machine loads. Size code 071 sets the stator diameter and mounting interface, while length code B indicates the second frame depth available in this size family and increases copper mass for higher power density. Dynamic balance remains at the standard grade to help minimize residual vibration. The shaft uses a keyway so couplings can transfer torque without slipping, and the motor has a shaft seal that helps protect internal parts from dust and coolant.

The centering pilot measures 95 mm, allowing the motor to seat precisely in compatible flanges and maintain accurate alignment during installation. Power and feedback leads exit on Side A, which supports straightforward cable routing in assemblies that require the connections on that end. The motor uses a single connector system for power and feedback connections, which keeps the interface compact and secure. A blocking brake is integrated, and its static capacity of 3.0 Nm keeps the load fixed when the drive is de-energized. This brake also supports controlled holding when the axis must remain in position after motion stops.
