Research and analysis of mechanical characteristics of three-phase asynchronous motor

Abstract Three-phase asynchronous motor is widely used in all walks of life. It is of great significance to study the mechanical characteristics of the motor for the correct selection and use of a motor. The expressions of the mechanical characteristics of a three-phase asynchronous motor include parameter expression, practical expression, and linear expression. Through the simulation analysis of different expressions of mechanical characteristics, the practical expression is usually used to calculate the three-phase asynchronous motor in practical application, which can avoid the tedious calculation of parameter expression. The parameter expression is more suitable for qualitative analysis. The linear expression is suitable for the linear segment of the motor mechanical characteristic.
