A motor controlling method includes a step of obtaining a stator current and a stator voltage, which are represented by a phasor, with respect to an αβ fixed coordinate system or a dq rotating coordinate system, a step of calculating an angle (ϕ) between the stator current and the stator voltage, a step of calculating a torque angle (δ) according to δ=sin−1[L·Is cos(ϕ)/ψm], where L is an armature inductance, ψm indicates a magnetic flux of a rotor magnet, and Is indicates a magnitude of the stator current, and a step of controlling the surface permanent magnet motor based on the torque angle (δ).
