Product Description:

The MDD071A-N-040-N2S-095PR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical commands into precise rotary motion for compact axes in assembly cells, feeders, and similar automation stations where fast response and repeatable positioning are required. The motor uses the size 071 frame with the short A length, which gives it a narrow profile while still supporting the dynamic behavior expected in tightly spaced machine layouts. This arrangement suits machines that need accurate motion without using a large motor body.

At standstill, the rotor can deliver a continuous torque of 2.2 Nm, so static loads remain supported without exceeding thermal limits. When energized at rated voltage, the shaft can reach a nominal speed of 4000 rpm, providing enough speed for direct-drive or gear-reduced layouts. A factory-installed blocking brake produces 3.0 Nm of holding torque, locking the axis during power loss or emergency stops. Position feedback is supplied through digital servo feedback (DSF), which allows the controller to maintain accurate speed and position regulation. Power, feedback, and brake lines exit through a single coded connector, which keeps the connection point compact and easy to route.

A centering pilot of 95 mm provides repeatable concentricity at the mounting flange, and standard balancing helps limit residual vibration over the working speed range. The shaft uses a keyway for positive torque transfer to pulleys or couplings, and the opposite side is closed. The motor is supplied with a shaft seal at the front bearing to help keep contaminants away from the bearing area. All electrical plugs are oriented to the right side of the housing, which can simplify cable routing when several axes are mounted in parallel. The enclosure uses the standard series casting, allowing the motor to fit common mounting arrangements used across the product line.
