Abstract: A motor control method and apparatus, a motor controller, a motor, and a storage medium. The motor control method comprises: acquiring an actual phase lead angle during operation of a motor (S101), acquiring an angle difference between the actual phase lead angle and a target phase lead angle (S102), and adjusting a commutation phase of an excitation voltage of the motor according to the angle difference (S103), wherein the target phase lead angle is an angle, leading a back electromotive force commutation phase of the motor, of the commutation phase applied to the excitation voltage of the motor when the motor reaches a target rotation speed, i.e. the angle leading the zero crossing point of the back electromotive force. By means of the control method, the motor gradually reduces the difference between an actual phase lead angle and a target phase lead angle during the process of constant change of the rotation speed of the motor, so as to achieve a smooth current, and avoid the problem that a large error between the actual lead angle and the target lead angle results in the zero crossing point of a back electromotive force leading the commutation phase of an excitation voltage, causing an error in excitation voltage commutation and an abnormal operation of the motor.
