Method for manufacturing magnetostrictive torque sensor device, and electric power steering apparatus |
摘要 |
A method for manufacturing a magnetostrictive torque sensor device includes the steps of: providing a steering shaft or another such rotating shaft with two magnetostrictive parts endowed with magnetic anisotropy; disposing detection coils around the magnetostrictive parts to detect changes in magnetostrictive characteristics of the magnetostrictive parts; providing a detection circuit for bringing out detection signals from signals outputted from the detection coils; and adjusting a gain of a gain adjuster included in the detection circuit.
