This motor control method includes: a step in which the combined magnetic flux, the stator current, and the stator voltage are acquired from a phasor representation using an αβ fixed coordinate system or a dq rotary coordinate system as a reference; a step in which the angle ϕ between the stator current and the stator voltage is calculated; a step in which the torque angle δ is calculated on the basis of formula (1), wherein L represents armature inductance, ψs represents the size of the combined magnetic flux, and Is represents the size of the stator current; and a step in which a motor is controlled on the basis of the torque angle δ.
