Independent Equipment Line

SINOWIN's core processes (machining, magnetizing, testing) run on an independent equipment line, with sourcing configured flexibly to each customer's requirements. The SINOWIN team spans Vietnam, India, Taiwan, and Singapore — engineering and management talent is not concentrated in any single country, giving customers stable support that isn't exposed to volatility in any one labor market.

Engineer Tools: Online Surface Flux Density Estimation

Estimate axial flux density from grade, shape and dimensions

Select grade (or enter manually)

Magnet Shape

Br (Gs)

Length L (mm)30.0 mm

Width W (mm)20.0 mm

Thickness T (mm, magnetization dir.)10.0 mm

Distance from pole face z (mm)0.5 mm

Smaller z means closer to the magnet surface; default is a typical Hall probe embed depth (0.45 mm)

With yoke (approx.: doubles magnetization-direction thickness)

Dimension Schema z

Estimated Axial Flux Density4216 Gs= 421.6 mT

Grade:N52

Estimated Br:14.5 kGs

Max Working Temp:≤80°C

Reference formula (actual result is computed numerically)

Bz = (Br / π) × [ arctan( W·L / (2z·√(4z²+W²+L²)) ) − arctan( W·L / (2(z+T)·√(4(z+T)²+W²+L²)) ) ]

Estimated value on the magnet’s central axis at distance z from the pole face. Actual measurements vary with probe type, gap, and material tolerance — engineering reference only.
