Abstract

PURPOSE: To increase the measuring accuracy of magnetic torque by cross sensor through the increased S/N, by applying the DC bias magnetic field toward excitation placing the measured object under high magnetic field range.
CONSTITUTION: When the DC bias magnetic field Hdc is applied to the measured object 30, the magnetization (Is) is caused. While the magnetization advances from the stage of magnetic wall movement to the saturation range, it turns by the angle ϕ from the magnetization easy axis A and it depens on the opposing rotary angle θ. This magnatization (Is) is respectively Isc and Isd viewed from the measuring axes C and D, and Isc and Isd when the angle between the axes C and D is 90 degree (the same length of the both cores for excitation and detection) are as expressed as equation I, and this magnetized component is the magnetization of the pathe on the measured object between the legs 11-12, 12-22 and 11-22, 12-24. Accordingly, the detected output when DC bias magnetic field is applied, is V0=KIsHdc sin(θ-ϕ)NeNdωIe, and it shows the magnetic torque. Where Ne and Nd are number of turns of exciting and detection coils respectively, ω is excited angular frequency, and Ie is the excited current.
