Product Description:
The 80Mph4.600S111-02 is a hybrid stepper motor distributed by B & R Automation within the 80M Stepper Motors series. Designed for open-loop or microstepped positioning, the unit converts digital pulse trains from a compatible drive into precise incremental rotation. It is suitable for pick-and-place gantries, small indexing tables, and auxiliary machine axes that require accurate movement at low speeds. When directly coupled to the load, the motor avoids gearbox backlash while providing useful low-speed torque in a compact package.
The housing has an IP65 rating, protecting the internal windings and integrated connector against dust and low-pressure water jets. This protection allows the motor to operate outside a control cabinet without requiring an additional cover in suitably rated installations. Shaft position is reported through a single-turn Hiperface encoder, enabling a compatible drive to monitor position and synchronize the motor with other axes when closed-loop control is required. The electromagnetic assembly uses a two-stack, high-torque configuration with an extended active lamination length for increased detent and dynamic torque under heavier loads. The motor is supplied with no brake, so drive current provides holding torque while the system is energized. Applications that must retain a stationary load after power is removed require an external holding mechanism.
The winding set uses an x1 (10^0) current multiplier within the manufacturer’s current-scaling system. A compatible drive applies this multiplier to map the rated phase-current value directly to physical amperes without further scaling. The unit carries design revision 02, which indicates minor mechanical updates, such as connector orientation, while retaining the established electrical constants. It also uses motor stack code 4 to associate the rotor-stator pairing with the appropriate magnetic data used by the drive. These current, revision, and stack values must be entered accurately when configuring the connected motion controller. Correct parameter mapping allows the controller to regulate phase current and interpret encoder feedback without applying an unintended conversion factor.
