Product Description:

The MDD071B-N-040-N2S-095GL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Serving digital drive controllers, it translates drive current into controlled rotary motion suitable for pick-and-place stations, indexing tables, and other automated axes that require repeatable speed and torque. A sealed circular connector provides the connection interface, and the standard aluminum housing dissipates heat without auxiliary cooling.

During continuous operation, the motor delivers 4.4 Nm of standstill torque, providing sufficient holding force for small to medium loads until motion commands arrive. Once acceleration begins, the rotor can reach a nominal speed of 4000 rpm, a figure that matches the 071 frame size and the B-length stator stack to balance inertia with dynamic response. An internal blocking brake produces 6.5 Nm of static torque to secure vertical or suspended axes whenever power is removed. Position and velocity data return to the controller through digital servo feedback, enabling tight current loops and rapid error correction. Power, brake, and feedback conductors exit on the left side of the housing, a layout that simplifies cable routing inside compact enclosures while keeping the connector area clear.

The flange centers on a 95 mm pilot diameter, ensuring concentric alignment with gearboxes or belt pulleys. Precision is preserved by standard balancing, which helps limit residual vibration at operating speed. The motor uses a plain shaft for rigid coupling, and it comes with a shaft seal to retain lubricant while helping block dust and coolant spray. The single-ended shaft configuration, without a side B extension, reduces overall length and eases mounting against bulkheads. This layout suits moderate-inertia axes used in assembly lines and packaging equipment.
