Description

technical field

[0001] The invention relates to the field of motor control, in particular to a method for controlling a motor. Background technique

[0002] With the development of industry and new energy vehicles, the application of three-phase motors is becoming more and more extensive. At present, vector control technology is generally used to convert the magnetic field coordinate system formed by three-phase electricity into a magnetic field coordinate system similar to that of DC motors. The excitation current and the torque current are separated, and then the calculation method similar to that of the DC motor (the input current is proportional to the torque) is used to realize the control of the speed or torque of the three-phase motor, such as figure 1 As shown, the control method needs to use the current sensor to measure the current of each phase, and then perform Clarke transformation (convert the three-phase stationary coordinate system into a two-phase stationary...
