Product Description:

The MDD071A-N-040-N2S-095GA0 is a synchronous servo motor engineered by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers in positioning axes where compact dimensions and fast speed changes are needed. The motor converts controlled current into rotary motion that can be coupled directly to machine elements through its shaft. When paired with a compatible drive, it supports closed-loop motion tasks in packaging lines, small handling robots, and textile machinery. This makes it suitable for compact machine sections where responsive motion must fit within limited installation space.

The motor reaches a nominal speed of 4000 rpm, allowing high cycle rates without overspeeding matched gearheads. At standstill, it delivers 2.2 Nm of continuous torque, and the laminated housing helps dissipate heat during continuous operation. A centering diameter of 95 mm aligns the frame on machine surfaces, while the electrical power and encoder plugs exit on side A to simplify cable routing in tight cabinets. The front connector carries phase, grounding, and sensor lines, and the plain shaft supports backlash-free clamping couplings because its surface is uninterrupted by a keyway. This layout reduces cable bending near the motor body and helps keep the connection area compact.

Position data is transmitted through digital servo feedback, allowing precise commutation and stable control without separate external sensors. The unit is supplied without a blocking brake, so any holding force at standstill must come from the drive or an external mechanical device. A molded shaft seal helps protect the bearing area from coolant spray and similar contamination. The 071 frame and short A length keep rotor inertia low for axes that reverse quickly, and standard rotor balancing helps reduce vibration during normal operation. That combination suits indexing, feed, and transfer movements that demand quick reversals and smooth tracking.
