The PHB42F Series NEMA 17 5-phase stepper motors provide precise 0.72° step movement with ±5% full-step accuracy for smooth, low-noise operation. Compact and reliable, they feature high holding torque and low inertia, ideal for applications where space is limited. With a maximum temperature rise of 80°C, insulation resistance ≥100 MΩ, and dielectric strength of 500 VAC for 1 minute, these motors ensure stable performance. Shaft radial and axial play are strictly controlled at 0.02 mm and 0.08 mm, respectively. Available with 5-wire connection and lengths starting from 40 mm, PHB42F motors are suitable for precision instruments, and miniature automation requiring fine motion control.
