MDD071B-N-030-N2S-095PL1
The MDD071B-N-030-N2S-095PL1 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into regulated torque and speed so automated machinery can hold position or follow programmed motion profiles with precise control. It is suited for axes that require controlled torque, speed regulation, and stable position holding during operation. The housing follows a standard enclosure format, and heat is removed by natural convection across its ribbed surface.
This model supplies a continuous standstill torque of 4.4 Nm, allowing stable force output while the shaft is held by the drive. Under rated excitation, it reaches a nominal speed of 3000 rpm, which matches common drive controller frequency tables for medium-inertia loads. Rotor concentricity is set by a 95 mm centering diameter, and balancing is performed to a standard grade that limits vibration at full speed. Power and feedback conductors exit on the left side through a plug-in connector, simplifying cabinet layouts that place drives on the same axis line. Internal position data is returned through digital servo feedback, giving the controller high-resolution information for commutation and error correction. A shaft seal is fitted to reduce lubricant loss at the coupling face, and the shaft end is supplied in a standard single-sided form to save space in compact mechanical frames.
The integrated blocking brake develops 3.0 Nm of static holding torque, keeping vertical or spindle loads stationary when power is off. Coupling to gearboxes or pulleys is completed with a keyway shaft profile, eliminating slip during acceleration. Physical dimensions correspond to motor size code 071, and the electromagnetic stack length is indicated by code B. Connector type, housing style, and shaft seal follow the standard options for the series.
