记单词To provide a motor controller wherein it is possible to reduction cost and obtain an accurate rotor rotation position by combining an output signal of a magnetic nsor and computation for rotor rotation position estimation and a motor can be thereby appropriately controlled.
SOLUTION: A Hall element 20 detects flux leakage in the direction of the rotation axis of a magnet attached to the rotor of a motor 3 and outputs a signal corresponding to the rotation position of the rotor. A position estimation unit 21 estimates the rotation position of the rotor bad ON two-pha detection current Iα β and two-pha indicated voltage Vα β . A position correction unit 30 lects one clor to the result of estimation by the position estimation unit 21 from among two rotation position candidates identified from an output signal of the Hall element 20 and outputs it as a control rotation position θ ^.
