Product Description:

The 80MPH3.300S114-01 is a hybrid stepper motor produced by B&R Automation as part of the 80M Stepper Motors series. Within automated assembly cells, packaging lines, and gantry axes, the unit converts digital pulse trains into discrete shaft movements so that programmable logic controllers can index loads without the complexity of a closed-loop servo system. Its NEMA 34 frame makes the device suitable for medium-torque motion tasks where repeatable step accuracy and a compact mounting arrangement are required.

The motor housing has an IP65 protection rating, which seals the stator against airborne dust and low-pressure water jets encountered on production floors. A square flange measuring 86 mm (NEMA 34) provides the mechanical interface for gearheads or mounting plates and supports rigid alignment of the rotor shaft. Electrical sizing uses a current base value of 30. When multiplied by the scaling factor of x1 (10⁰), the control system reads the numerical entry directly as the operating phase-current setting. For position verification, the shaft integrates an ABR incremental encoder, which generates dual-channel quadrature signals so motion controllers can detect missed steps and perform precise homing routines without external position sensors.

Design iteration 01 incorporates material and winding updates while retaining compatibility with the applicable drive parameters. The rotor remains free when unpowered because the motor has no brake, so a mechanical lock or other external restraint must hold the load when the axis is de-energized. The flange uses size code H, which indicates the bolt pattern and pilot depth used for this 80M motor configuration. Internally, a two-stack arrangement balances detent torque and step resolution, while motor-stacks code 3 indicates the lamination height selected for this torque range. The integrated encoder also gives the controller an independent motion signal, allowing it to compare commanded movement with actual shaft rotation during operation.
