Product Description:
The 80MPF5.250S113-01 is a motor unit produced by B & R Automation within the 80M Stepper Motors series. It converts precisely timed current pulses into fixed angular increments, allowing conveyors, indexing tables, or dosing pumps to reach repeatable positions without closed-loop feedback. The square frame simplifies installation in machinery where economical yet accurate axis control is required across packaging, semiconductor, and small material-handling stations. Its stepper motor design supports controlled incremental movement when paired with a compatible drive and correctly configured current settings.
This model is assembled with no brake, so mechanical locking must be provided externally whenever holding torque is critical after power is removed. Position is reported through a single-turn SSI absolute encoder, giving the drive immediate awareness of the rotor angle at power-up and removing the need for homing routines. A flange diameter of 60 mm aligns with IEC size conventions and provides four threaded holes for rigid attachment to gearboxes or mounting plates. The housing is sealed to IP65, preventing dust and low-pressure water spray from reaching the bearings or windings. The internal lamination height follows motor stack code 5, providing higher rated torque than shorter stacks while keeping the overall mass moderate. This arrangement supports installations exposed to airborne particles or occasional water spray, provided that mating components and cable connections are sealed correctly.
Electrical adaptation is simplified by the current multiplier setting of x1 (10^0), indicating that the winding tables may be used without scaling factors during drive configuration. The mechanical drawing has design revision 01, so the mounting and connector locations correspond to the first released design. The flange has the size designation F, which distinguishes this mounting pattern from the larger G and smaller E brackets offered in the same series. As an 80MP stepper motor, its magnetic geometry matches drive tables optimized for two-phase microstepping. Torque capability comes from a rotor made with three stacks, an arrangement that balances detent torque smoothing with moderate inertia for responsive acceleration. Proper drive adjustment helps the motor maintain predictable step behavior during changes in speed, direction, and mechanical load.
