Model representation of three-phase asynchronous motor

About the model representation of three-phase asynchronous motor. In fact, different parameters of the three-phase asynchronous motor its model representation is different. For example, for the general function asynchronous motor, the power is 550W, the number of poles is four, and the frame number is 80. Then the model of the three-phase asynchronous motor under this parameter is ye2-801-4-0.55kw. Because the model of ordinary three-phase asynchronous motor is Ye2, if the number of poles is changed to 6 and the power is changed to 750W, then the model is ye2-90s-6-0.75kw. Ye2 for ordinary motor, YEJ for electromagnetic brake motor, YVF2 for variable frequency speed motor, YL / YC for single-phase capacitor motor. If the motor types used are different, for example, the model representation of three-phase asynchronous motor is different. For example, yej8014-0.55kw (electromagnetic brake motor model) or yvf2-801-4-0.55kw (variable frequency speed motor model), yl7112-0.25kw (double capacitance single-phase motor). Therefore, the model representation of three-phase asynchronous motor with different types, power, frame number and motor pole number is different. We should also pay attention to differentiation when purchasing
