Abstract: To provide a motor controller capable of correcting the detection value of turning angle of a rotor by a hole sensor for motor control, without using a dedicated tool for calibration such as encoder.SOLUTION: A motor controller 1 control a motor by using the output values from first, second and third hole sensors arranged, at intervals, in the rotation direction of the rotor 20. The motor controller 1 obtains an angle corresponding to a value of tangent, obtained by using the value of sine and the value of cosine, where the value of sine is the output value of a first hole sensor, and the value of cosine is obtained by adding the additive inverse of the output value of a third hole sensor to the output value of a second hole sensor and then dividing by 2, as the rotation angle of the rotor 20. At this time, the value of sine or the value of cosine is corrected by using the ratio of the maximum value of first amplitude and the maximum value of second amplitude, so that the first amplitude, i.e., the amplitude of the value of sine matches the second amplitude, i.e., the amplitude of the value of cosine.SELECTED DRAWING: Figure 1
