Product Description:
The SH1424-5241 is a two-phase stepping motor produced by Sanyo Denki and supplied under the F SANMOTION Stepping Motors series. This hybrid stepper generates discrete angular increments so a controller can translate digital pulses directly into mechanical motion. In automated assembly, packaging, or small gantry axes, the motor’s precise positioning capability removes the need for complex feedback devices while still driving belts, screws, or indexing tables with repeatable accuracy. Its 42 mm frame makes it suitable for compact equipment and laboratory instruments where space is limited.
The motor’s fundamental displacement per command pulse is 0.9°, so 400 full steps complete a revolution and allow fine resolution in open-loop drives. A 42 mm square frame mates with NEMA 17 brackets, and four face bolts are located on a 22 mm pilot for concentric mounting. Static shaft retention is supplied by a holding torque of 0.48 N·m, which is adequate for light linear stages. Each phase draws up to 2 A per phase. This current encounters a resistance of 1.25 Ω per phase and an inductance of 3.75 mH per phase, values that influence drive voltage and microstep frequency. These electrical constants establish the time constant and limit acceleration before synchronism is lost.
The laminated stack extends only 48 mm from the mounting face, and the rotor and housing weigh 0.38 kg, limiting inertial load on lightweight carriages. The motor has a compact 5 mm diameter D-shaped output shaft that provides positive coupling while resisting slippage. Its internal inertia of 0.089 × 10⁻⁴ kg·m² enables rapid starts when paired with the standard bipolar wiring configuration. The radial bearings accommodate a 20 N load, while the thrust path tolerates a 10 N load, preserving bearing life when pulleys or lead screws apply radial or axial stress. An M3 × 0.5 mounting thread supports accessory encoders, and the centering pilot aligns compatible gearheads.
