Product Description:

The MDD071A-N-040-N2S-095GR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical power from the drive into rotational motion for positioning or velocity tasks in automated machinery such as pick-and-place axes or packaging spindles. That arrangement makes it suitable for servo axes that need repeatable starts, stops, and commanded speed changes. Its compact 071 frame and standard housing help it fit into tight mechanical envelopes while maintaining compatibility with Indramat drive families.

The motor can develop a continuous stall torque of 2.2 Nm, so it can maintain torque at zero speed when energized. During operation, it reaches a nominal speed of 4000 rpm, allowing rapid cycle times in applications that demand quick indexing. A centering diameter of 95 mm supports repeatable concentric alignment to the mounting surface, which helps limit vibration during operation. Rotor position is reported through digital servo feedback, giving the controller high-resolution data for tight speed and torque loops. Mechanical output is transferred through a plain shaft, which avoids keyway stress concentrations and suits clamp-style couplings common in light- to medium-duty automation.

The motor uses standard dynamic balance, and the A length code keeps overall mass low for faster acceleration. The 071 size uses an integral Right side power and feedback exit to reduce cable bends in side-mounted cabinets, while a keyed circular connector provides a secure electrical interface. Mechanical holding is handled externally because the motor is shipped without a blocking brake. A fitted shaft seal helps limit coolant or dust ingress at the output end, and the standard shaft end on side A avoids overhung loads on the rear bearing set.
