Product Description:

The 80MPF3.250S000-01 is a hybrid stepper motor manufactured by B&R Automation within the 80M Stepper Motors series. The unit combines discrete angular positioning with open-loop current control, making it suitable for indexing tables, pick-and-place axes, and other motion stages where repeatable step accuracy is required in industrial automation. Its hybrid rotor structure supports precise incremental movement, and the motor is intended for applications that rely on commanded step sequences rather than closed-loop servo correction. That arrangement is common in machinery that values simple drive integration and consistent repeatability over high-speed servo behavior.

In this configuration, the motor is supplied with no brake, so holding torque is produced electromagnetically rather than by a mechanical lock. The winding current uses a multiplier of x1 (10^0), which allows drive parameters to be entered directly without numeric scaling. A square front-mount flange of 60 mm forms the mechanical interface, and the size character F identifies that flange format in the model code. The rotor and stator use stack code 3, which indicates the active iron length associated with this motor version. The protection level is standard, so the motor should be installed in a protected area away from washdown exposure.

Feedback hardware is omitted because the motor has no encoder, which keeps operation in open-loop control when paired with a calibrated drive. The design revision is 01, indicating a product revision that does not change the external mounting envelope. The motor is classified as an 80MP Stepper Motor, matching the electrical characteristics used for this winding family. Dynamic torque rise is influenced by the laminated core geometry of 2 stacks, which balances inertia and holding capability for mid-range indexing speeds. This layout supports steady indexing behavior in applications that need predictable motion without separate feedback hardware.
