MDD071B-N-040-N2S-095PL2
The MDD071B-N-040-N2S-095PL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts regulated current into precise angular motion for tasks such as indexing, contour following, and velocity holding inside automated cells and conveyor modules. Accurate position verification is supplied through digital servo feedback (DSF), which returns rotor data to the drive for closed-loop control and supports stable motion during changing load conditions.
This model produces a continuous standstill torque of 4.4 Nm, giving the drive enough static force to support loads during dwell periods without excessive thermal stress. Under rated excitation, it can reach a nominal speed of 4000 rpm, allowing high-cycle positioning and quick response in fast-moving axes. A blocking brake is integrated, and its mechanical holding capability is rated at 6.5 Nm, so the motor can help keep a vertical axis in place after power is removed. For mounting alignment, the front face includes a 95 mm centering diameter that seats the motor concentrically to the machine frame and helps reduce radial runout at the coupling.
Power and feedback connectors are oriented to the left, which can simplify cable routing along side-mounted tracks and help keep the cable path clear of nearby machine parts. A shaft seal is fitted to help block oil or coolant from entering the bearing cavity, and the output shaft is machined with a keyway so torque can be transferred through keyed couplings with secure mechanical engagement. Rotor balance follows the standard grade to limit vibration as speed increases. The motor also uses a B-length housing and a size 071 stator stack, with a standard housing finish and no secondary shaft on side B.
