The invention provides a locked-rotor torque control method and device of a motor and an electric vehicle, the motor comprises a first-phase stator winding, a second-phase stator winding and a third-phase stator winding, and when the motor is in a charging mode, the first-phase stator winding and the second-phase stator winding are connected in parallel and then connected with the third-phase stator winding. The method comprises the following steps: acquiring a current rotor magnetic field angle of the motor when the motor is in a charging mode; and determining a target stator magnetic field angle of the motor according to the current rotor magnetic field angle and a mapping relation between a preset rotor magnetic field included angle and the locked-rotor torque. And the first phase current of the first phase stator winding and the second phase current of the second phase stator winding are controlled, so that the stator magnetic field angle of the motor is the target stator magnetic field angle. By adopting the method and the device, the locked-rotor torque of the motor can be ensured to be minimum when the motor is in the charging mode, so that the charging safety is improved, and the applicability is high.
