MDD071A-N-030-N2T-095PL1
The MDD071A-N-030-N2T-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. The unit is intended to drive machinery axes controlled by digital drive controllers, converting commanded current into precise rotational position and velocity for automated tooling, packaging stations, and handling modules. In typical use, it works with a compatible servo controller that closes the current, speed, and position loops in real time. This arrangement allows the axis to respond quickly to load changes during indexing, transfer, and synchronized machine movement. The motor has a compact housing and a single front shaft, which helps it fit machinery where installation space is limited.
The motor reaches a nominal speed of 3000 rpm, allowing fast axis movement while maintaining responsive servo behavior. Under continuous stall conditions it produces 2.2 Nm of torque, which is the continuous holding torque available without exceeding thermal limits. A centering diameter of 95 mm aligns the housing accurately on mounting surfaces and helps maintain concentricity between the rotor and connected mechanics. Position data are relayed to the controller through digital servo feedback, and multi-turn position retention is handled by the integrated multiturn absolute encoder, so the drive can retain position information after power loss. This feedback arrangement supports repeatable positioning during start-stop motion and coordinated axis operation.
When power is removed, a blocking brake secures the shaft with 3.0 Nm of holding torque to help prevent unintended movement on vertical or load-bearing axes. Power and feedback conductors exit on the left side, which can simplify cable routing when the drive is mounted to the motor's right. The output shaft uses a keyway for standard keyed couplings, and a shaft seal helps limit dust entry and lubricant migration at the bearing area. Standard rotor balancing supports smooth rotation across the operating speed range and helps reduce vibration during normal servo motion. These features make the motor well suited for repeated cycling in automated equipment that depends on stable motion control.
