The PHB28F Series NEMA 11 5-phase stepper motors offer precise 0.72° step movement with ±5% full-step accuracy, ensuring smooth and low-noise operation. Compact and miniature in size, these motors are ideal for space-constrained applications. They feature high reliability with a maximum temperature rise of 80°C, insulation resistance ≥100 MΩ, and dielectric strength of 500 VAC for 1 minute. Shaft radial and axial play are minimized to 0.02 mm and 0.08 mm, respectively, ensuring consistent performance. With 5-wire connection and lengths starting from 31 mm, PHB28F motors are perfect for medical devices, precision instruments, and miniature automation systems requiring fine motion control.
