Abstract
The present invention provides a rotor position detection device including a sensor having a first chip and a second chip which are aligned with a first line and detect a change in magnetic flux in a sensing magnet, wherein the sensor has the first line which is inclined with respect to a second line passing through any one of the first chip and the second chip in a radial direction of the sensing magnet. Accordingly, the present invention provides an advantageous effect of detecting a rotational direction and a precise rotational angle of the motor by utilizing one sensor.
