Product Description:

Bosch Rexroth Indramat manufactures the MDD065A-N-040-N2L-095GR0, a member of the MDD Synchronous Motors series. This motor for digital drive controllers has size 065 and length code A, giving compact dimensions suitable for multi-axis machines in printing, electronics, and small material-handling cells. Its compact frame helps where axis spacing is limited and moving assemblies must stay light. Integrated electronic commutation works with the matching drive to generate smooth torque across the full speed range, so the axis can accelerate rapidly to target velocity and reverse direction without mechanical backlash.

During continuous stall operation, the motor provides 0.8 Nm of torque, which indicates how much load it can hold without rotation when energized. The rated mechanical speed reaches 4000 rpm, indicating the maximum synchronous velocity attainable under nominal voltage and frequency. Position and velocity data are returned over digital servo feedback (DSF), allowing the drive to close the control loop every cycle. This feedback arrangement helps the drive maintain stable positioning and speed regulation during repeated starts and stops. Power and feedback conductors terminate on a connector that is factory configured so wiring can be completed rapidly, and all terminations face to the right side of the housing to simplify cable routing inside compact cabinets.

The front flange offers a centering diameter of 95 mm, ensuring concentric alignment with gearboxes or mounting plates. A plain shaft transmits torque without keyways, reducing runout when clamp couplings are used. Because the design is supplied without a blocking brake, holding force must be provided externally or by the drive's stator current when the axis is idle. The motor relies on a shaft seal to protect internal bearings, and its standard housing and standard dynamic balancing permit direct mounting without additional vibration isolation. The shaft seal also helps keep contaminants away from internal bearing surfaces during normal industrial operation.
