Product Description:

The 80MPH4.500S000-01 is a stepper motor built by B & R Automation for the 80M Stepper Motors series. As a pulse-driven actuator, it rotates through a fixed angle with every command step, allowing machine builders to position light to medium loads without continuous position correction. Typical tasks include indexing small conveyors, metering fluid pumps, and driving cut-to-length knives where repeatable motion is required in compact equipment.

The motor bolts to machinery through an 86 mm NEMA 34 flange, so it fits the square mounting pattern used by many existing drives. Its windings have a phase-current identifier of 50, and the documented x1 (10⁰) multiplier leaves the corresponding value unchanged. This arrangement simplifies selection of compatible drive settings without requiring an additional conversion factor. Because the product is supplied with no encoder, the application must rely on commanded step counts and proper load-inertia matching to avoid position loss. The housing has a standard protection level that shields the stator from general-purpose shop debris, but it is not sealed for washdown areas. The 80MP designation places the electromagnetic design within the 80 mm frame group used across the manufacturer’s motion platform.

Mechanical retention is simplified because the shaft is delivered with no brake, allowing it to turn freely when motor power is removed. Static loads may therefore require an external holding device if movement after shutdown would create an operational problem. The H frame code indicates the flange-size group within the 80M series, while stator-length code 4 identifies the motor’s extended torque-producing section. Internally, the lamination stack uses a two-stack, high-torque arrangement, increasing the available pullout torque at low speed without unnecessarily enlarging the surrounding machine layout. Design revision 01 indicates the first released design iteration for this motor configuration.
