MDD071A-N-040-N2T-095PL2
The MDD071A-N-040-N2T-095PL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is used to generate closed-loop rotary motion in automation axes that require precise speed and position regulation. The unit is delivered in a standard housing and uses standard balancing, so it can be mounted without additional counterweights or special vibration damping hardware. Because it is intended for digital control, the paired drive can monitor rotor position continuously and correct deviations during acceleration and deceleration.
This model supplies a continuous standstill torque of 2.2 Nm, enabling stable force production when the shaft is held against load. Under rated electrical excitation, it reaches a nominal speed of 4000 rpm, matching drive controllers intended for fast servo response. Mechanical alignment in the machine frame is aided by a centering diameter of 95 mm, while the shaft exits with a keyway to help couplings or pulleys resist slip during load changes. Power and feedback conductors leave on the left side through a single industrial connector, which helps routing when space around the motor is limited. The shaft end is supplied in standard form without a secondary shaft on side B, and the A motor length keeps the housing short.
Position feedback is provided by an integrated multi-turn absolute encoder that reports revolution count and angular position to the drive over digital servo feedback (DSF). A blocking brake rated at 6.5 Nm keeps the rotor locked during power-off events, which is useful on axes that must hold position at standstill. Protection against lubricant migration and dust ingress is supported by the factory-installed shaft seal. The motor size code 071 corresponds to this frame size within the MDD range, and it identifies the stator format used for the motor body. This feedback and brake combination allows the drive to retain position information after restart and hold the axis when electrical torque is removed.
