MDD071B-N-040-N2S-095PA2
The MDD071B-N-040-N2S-095PA2 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers that require rapid torque modulation and precise position control on automated machine axes, pick-and-place actuators, and packaging lines. The compact motor housing suits installations where mounting space is limited but repeatable motion is still required. That combination makes it suitable for axes that must accelerate quickly, stop accurately, and then hold position between machine cycles.
The motor delivers a continuous standstill torque of 4.4 Nm, which indicates the load it can hold at zero speed without excess heating. Its rated mechanical speed reaches 4000 rpm, allowing fast indexing and high linear feed rates when the drivetrain is matched correctly. For emergency stops or dwell periods, the blocking brake applies up to 6.5 Nm of static torque. Accurate rotor information is supplied through digital servo feedback, which gives the drive high-resolution position data for closed-loop control. A centering pilot of 95 mm helps align the motor accurately with mating flanges, and standard balancing supports smooth running during repeated reversals.
The housing includes an integral shaft seal to help keep coolant spray and light dust away from the bearings. Power and feedback leads exit through a connector on Side A, which helps maintain a predictable cable path in compact machine layouts. The motor uses frame size 071 with length code B, giving a mid-range envelope that suits many servo applications. Torque is transferred through a shaft with a keyway, which helps prevent slip under frequent starts and reversals. There is no shaft projection on side B, which reduces the rear clearance needed behind the motor. This layout is useful where adjacent axes, guards, or cable carriers leave little room around the back of the motor.
