Product Description:

The MDD071A-N-030-N2T-095PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts command signals into mechanical rotation for positioning, feed-axis, and cyclic transport tasks in automated machinery. An internal blocking brake and sealed housing allow the unit to hold load torque and operate in oil-mist or dust-laden cabinets common in industrial automation cells.

The motor reaches a nominal speed of 3000 rpm, meaning it can sustain that rotational velocity under rated load without exceeding thermal limits. Continuous stall capacity is 2.2 Nm; this torque is available whenever the rotor is energized but motionless, which is useful for vertical axes that must resist gravity. The motor has a centering diameter of 95 mm for pilot fit on the machine frame, helping ensure coaxial alignment and reduce vibration. Position information is supplied by the integrated multi-turn absolute encoder, which reports shaft angle and revolution count to the controller without homing moves after power cycles. Power and feedback conductors exit on Side A, simplifying cable routing when the motor is mounted with its flange toward the work zone.

Dynamic holding is augmented by a blocking brake rated at 3.0 Nm, allowing the shaft to stay locked during emergency stops or power loss. Motion feedback reaches the drive through digital servo feedback (DSF), enabling high-resolution velocity loops without additional sensors. Electrical power is delivered through a sealed connector that mates with the drive cable, and mechanical energy is transmitted through a keyway shaft profile that helps prevent slip under cyclic loads. Standard balancing limits residual vibration, the A-length housing keeps overall mass low, and an integral shaft seal protects the internal bearings against coolant splash.
