Product Description:

The 80MPF1.250S114-01 is a hybrid stepper motor produced by B&R Automation within the 80M Stepper Motors series. It forms the rotary element of many mid-range positioning axes, translating clock and direction pulses from a motion controller into discrete angular steps without requiring a closed-loop servo system. This enables packaging stations, light conveyors, and assembly fixtures to achieve repeatable indexing while keeping wiring simple. The motor’s compact frame, reinforced bearing system, and fully sealed housing allow direct installation on a machine frame or inside a distributed I/O island.

It is supplied with no brake, so static holding relies on residual detent torque or a continuously energized winding, and vertical loads require an external clamp. Rotor position is verified by an ABR incremental encoder that streams two quadrature channels for directional counting and optional index referencing. The square front face measures 60 mm, matching the industry-standard NEMA-23 bolt pattern and simplifying retrofit work. The 80MP Stepper Motor designation indicates compatibility with the electrical constants used across B&R’s 80 mm family, allowing a common drive profile. The housing carries an IP65 rating, blocking dust and low-pressure water so the motor can be mounted in washdown or cutting-fluid areas without a secondary enclosure.

For drive configuration, the published phase current is multiplied by x1 (10^0), meaning the listed numeric value can be entered directly into the controller. The mounting interface is further characterized by flange code F, which sets the pilot diameter and hole spacing for repeatable alignment. Electromagnetic length is limited to 1 stack, reducing inertia and improving acceleration in stop-and-go indexing cycles. Design revision 01 indicates the first production release, with the documented mechanical dimensions, encoder protocol, and winding parameters used for this version.
