Product Description:

B & R Automation builds the 80MPF1.250S000-01 as part of its 80M Stepper Motors series. The unit serves in industrial automation as a positioning actuator that advances in fixed angular steps, allowing a control system to move machine axes to defined coordinates without a feedback loop. In that role, each commanded pulse advances the shaft by a known increment, so the drive can perform indexed movement and speed control by managing pulse rate and sequence. It is categorized as an 80MP stepper motor and can operate in full-step or microstep drive modes, depending on the selected controller.

The mechanical interface uses a 60 mm square flange, and the associated size code is F, so the motor can mount directly to gearboxes or brackets that share this pattern. Electrical current ratings use a scaling factor of x1 (10^0), which means the listed current values are applied without additional multiplication when the drive data is interpreted. That keeps the current data straightforward to read because the values are used directly. The motor is design revision 01, which marks the first released version of this configuration. Position sensing hardware is omitted, and the motor is supplied with no encoder, so the application must rely on open-loop step count or an external sensor for absolute position.

Because there is no brake, holding torque comes only from the energized windings, which is common in machinery that remains powered at a stop or uses a self-locking mechanism. That arrangement is typical on axes where load holding after power removal is handled by the machine mechanism instead of the motor. The winding set uses a 1 stack configuration, which keeps rotor inertia lower than taller stack arrangements and supports mid-range acceleration demands. The motor has the Standard protection level of the series, making it suitable for cabinets or other sheltered installations without washdown exposure or corrosive media.
