MDD071B-N-060-N2T-095PR2
The MDD071B-N-060-N2T-095PR2 is a three-phase permanent-magnet synchronous motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded stator currents from an inverter are converted into precise mechanical rotation. The motor is used on industrial automation axes such as indexing tables, pick-and-place arms, and other motion systems that require repeatable positioning, high acceleration, and a compact installation footprint.
This model uses a centering diameter of 95 mm, allowing the motor flange to seat accurately in machine frames and maintain coaxial alignment with the driven mechanics. At standstill, it can deliver a continuous torque of 4.4 Nm, so static loads such as tensioners or vertical axes can remain supported without overheating. During operation, the rotor can reach a nominal speed of 6000 rpm, which suits high-speed production cycles when the motor is paired with a compatible drive. Power and feedback conductors exit on the right side, and a single plug-in connector simplifies installation by combining phase and signal contacts in one housing. A standard dynamic balance grade helps minimize vibration during operation.
Position retention during power-off is handled by an integrated blocking brake that provides 6.5 Nm of holding torque, eliminating the need for external clamps on vertical or load-sensitive axes. Motion feedback is provided through digital servo feedback (DSF) from an integrated multi-turn absolute encoder, giving the controller absolute shaft position across multiple revolutions for fast startup. Mechanical coupling uses a keyway shaft, and a factory-installed shaft seal helps limit lubricant ingress. The motor has size code 071 and length code B, uses a standard housing, and comes without a side-B shaft end, which keeps the overall envelope compact while supporting the stated torque and speed range.
