Magnetic Design Tool: Angel Sensors
The Magnetic Design Toolmeasures the magnetic field at the sensor by calculating the valid air-gap (distance between magnet surface to sensor) based on magnet size and remanence (diametrical magnetization). It also determines the worst-case angle error caused by assembly tolerances such as tilts and eccentricities by considering the most unfavorable rotation position for the maximum assembly tolerances combination. All results reflect worst-case scenario simulations.
