Product Description:

The MDD071A-N-030-N2T-095GR0 synchronous motor is built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and is typically installed in compact axes where closed-loop velocity and position control are required. The unit corresponds to motor size 071 with the short A length code, which keeps mass and rotor inertia low for light- to medium-duty motion tasks. This layout suits applications that need accurate motion control without the larger footprint of a longer motor housing.

At standstill, the motor can sustain a continuous torque of 2.2 Nm, so the energized shaft can hold a steady load while not rotating. Under rated excitation, it reaches a nominal speed of 3000 rpm, which fits common operating ranges in handling and packaging equipment. A centering diameter of 95 mm provides the pilot fit on the mounting flange and helps keep radial runout within the DIN tolerance class. Rotor position is reported by an integrated multi-turn absolute encoder, allowing the controller to recover absolute position after power loss. The encoder sends digital servo feedback signals to the drive, reducing analog drift and supporting stable closed-loop operation. The housing uses the sealed construction standard for this motor series.

The power and feedback lines use a connector interface, and all plugs exit on the right-side connection face, which simplifies cable routing inside narrow cabinets. The rotor uses a plain shaft, and there is no secondary output on side B, so couplings or pulleys must be mounted only on the driven end. A dynamic lip is installed around the journal, so the motor is supplied with a shaft seal to help limit dust or coolant ingress. Because the motor is delivered without a blocking brake, static holding must be provided by drive torque or an external clamping device. Standard dynamic balancing helps control residual vibration during high-speed operation.
