MDD071B-N-040-N2T-095PR2
The MDD071B-N-040-N2T-095PR2 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It serves as the electromechanical actuator for digital drive controllers in automated machinery and handling systems. The motor supports tight velocity and position regulation during repeated indexing, transfer, and positioning tasks. This makes it suitable for axes that must start, stop, and reverse with consistent response under changing process loads.
This model delivers a continuous standstill torque of 4.4 Nm, allowing the drive to hold load torque without thermal overload when the rotor is locked. Under rated electrical frequency, it can reach a nominal speed of 4000 rpm, matching mid-range velocity demands common to packaging spindles and pick-and-place axes. A centering diameter of 95 mm aligns the housing precisely with the machine flange for accurate mounting. The power and feedback terminations exit on the right side, which can simplify cable routing when space is limited beside the motor. Cabling is completed through a single connector interface that resists vibration and keeps the electrical connection compact. The motor also has a standard housing with size 071 and length code B.
A blocking brake integrated at the non-drive end supplies 6.5 Nm of static torque so vertical loads remain stationary when power is removed. Closed-loop accuracy is provided by an integrated multi-turn absolute encoder, while the drive evaluates those signals through digital servo feedback (DSF) for precise commutation and position monitoring over multiple revolutions. The shaft uses a keyway to transmit torque into couplings or pulleys, and a shaft seal is fitted to limit lubricant migration and help protect the internal bearings from splash exposure. A standard shaft end without a side B extension keeps the layout simple and avoids added overhung mass on the rear of the motor.
