Abstract

An angular position sensor including a magnetic field generator means and a magnetic sensor means. The magnetic field generator means produces a magnetic field. The magnetic sensor means has a first magnetic sensor element, a second magnetic sensor element, and a third magnetic sensor element each for providing an output signal depending on a direction of the magnetic field. One of the magnetic field generator means and the magnetic sensor means rotates in conjunction with the target object. The magnetic sensor elements are located so as to provide output signals having different phase differences by allowing the magnetic sensor means to rotate relative to the magnetic field generator means. The magnetic sensor elements are also located such that an output signal of each magnetic sensor element has a phase different from an inverted phase of an output signal of the other two magnetic sensor elements.
