MDD071A-N-060-N2S-095PR1
Bosch Rexroth Indramat manufactures the MDD071A-N-060-N2S-095PR1 in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from the inverter into mechanical rotation for positioning or velocity-regulated axes in industrial automation cells. A plug-in connector handles all stator leads.
The unit can sustain a continuous torque of 2.2 Nm at standstill, allowing it to hold loads without overheating when no motion is required. When the drive issues speed commands, it reaches a nominal velocity of 6000 rpm, matching high-throughput machines that cycle rapidly. A centering diameter of 95 mm aligns the motor on the mounting pilot and helps keep radial runout within acceptable limits. The power and feedback conductors exit on the right side, simplifying cable routing when the drive electronics are placed on that side. Rotor position is reported through Digital servo feedback (DSF), which provides incremental data plus a multiturn absolute value so the controller knows the shaft angle after power-up. The 071 frame size combined with the compact A length code reduces mass inside tight machine frames, and the standard aluminum housing dissipates losses to ambient air.
A blocking brake is integrated and can apply a static torque of 3.0 Nm, preventing vertical or suspended loads from drifting during emergency stops. Power is delivered through a keyway shaft, which mates with keyed couplings to prevent slip under peak acceleration. Contaminant ingress along the output journal is limited because a shaft seal rides against the flange. Vibration during operation is controlled by standard balancing, which reduces the need for field correction. The motor uses a single-ended shaft design, a right-angle connector orientation, and a standard housing. This layout suits drive trains that use keyed pulleys or gearboxes.
