Abstract
The present invention discloses an angular position sensor, which includes a rotor core as well as a stator core coaxially around this rotor core. Between the rotor core and the stator core is a first air gap, and inside the rotor core a second air gap, which is provided inside with a hard magnet. The stator core has a third air gap inside, which is provided inside with a magnetic flux sensing element. It is obvious that the present invention, by substituting the combination of the hard magnet and the rotor core for the design of ring magnet in the prior art, obtains the good linearity within a wider range.
