| Research Abstract |
Angles hall sensors in a three dimensional hall probe are not directed along the x, y and z axes correctly, and it causes an error of field measurement.Automated measurement system for the sensor angles of hall probe is developed. The system consists of 3-axis Helmholtz coils and 5 axis positioning stage. The parts of positioning stage inside the coils are made of non-magnetic materials in order to avoid field distortion. A pickup coil is attached to the positioning system, and the field direction of the Helmholtz coil is measured against the mechanical axis of the stage.
