Physical quantity conversion sensor and motor control system using the same
摘要
<p>A first sensor element 100-1 outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element 100-2 outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section 200-1 converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into a signal representing the rotation angle of the motor.</p>
