MDD071A-N-040-N2S-095PR0
The MDD071A-N-040-N2S-095PR0 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Built for operation with digital drive controllers, the motor converts electrical power into precise rotary motion for positioning and velocity control in automated machinery. Its 71-frame construction suits packaging lines, pick-and-place axes, and general material-handling stations where compact servo axes require accurate speed and position control over repeated start-stop cycles. The permanent-magnet rotor also supports responsive motion when the motor is paired with a compatible digital controller.
The motor provides a continuous torque of 2.2 Nm, allowing low-inertia loads to be held without extra gearing. A rated speed of 4000 rpm balances cycle time with mechanical wear for moderate-speed axes. That speed class supports short travel moves and quick index operations in automated equipment. Mounting is guided by a pilot fit of 95 mm on the front flange, which helps maintain concentric alignment with the driven assembly. Power and feedback cables exit on the right side, and a detachable connector simplifies cable routing. Closed-loop control accuracy is supported by integrated digital servo feedback, which delivers high-resolution rotor position data to the controller.
A standard dynamic balance grade limits residual vibration and supports smooth operation in the compact size 071 with length code A. The unit is delivered without a blocking brake, so static holding torque must be provided electrically or through external mechanics. Its single output shaft features a keyway and includes a shaft seal, which helps prevent lubricant migration toward the bearings. A standard housing and a single-ended shaft keep the overall envelope short for tight machine frames, while the absence of a side B shaft end leaves more room for compact coupling arrangements.
