Product Description:
The 103F7852-8041 is a hybrid stepper motor manufactured by Sanyo Denki as part of the StepSyn Stepping Motors series. In automation cells, it is coupled to microstepping or full-step drives to translate command pulses into discrete shaft positions, allowing conveyor diverters, small indexing tables, or laboratory dispensers to be positioned without an encoder. The motor’s square housing and standardized mounting face allow installation in compact frames where accurate open-loop motion is suitable. Its pulse-driven operation provides repeatable incremental movement when paired with a compatible stepper motor drive.
A square body measuring 60 ± 0.7 mm on each side keeps the footprint small, while a body length of 55 mm balances torque capacity against overall depth. The motor provides a holding torque of 0.93 N·m, which indicates the maximum load the shaft can resist while the windings are energized and the rotor is stationary. Dynamic performance is influenced by a rotor inertia of 0.4 × 10⁻⁴ kg·m², supporting fast start-and-stop movement with limited overshoot. The assembly weighs 0.78 kg, which should be considered when sizing linear slides and mounting brackets. A 24 mm pilot bore seats the front flange, and four M4 × 0.7 threaded holes with at least 8 mm of thread depth secure the motor to the supporting structure.
Power connections use AWG 22 leads that extend a minimum of 305 mm, providing enough length for routing to the motor drive or terminal block. The UL3266 insulation tolerates elevated cabinet temperatures and tight bending radii. The mounting face has a center-to-center hole spacing of 49.5 ± 0.2 mm, aligning the motor with compatible gearheads and mounting plates. Output torque is transmitted through a shaft with a diameter of 8 mm with a tolerance of -0.015/+0 mm. A 7.5 ± 0.1 mm shaft flat supports secure engagement with set-screw couplings and helps prevent slipping under load. The smooth pilot diameter transition maintains concentric alignment between the motor and connected load, limiting radial runout during rapid step changes.
