Abstract:

Purpose. To choose general control algorithm for asynchronous motor, to obtain mechanical specifications for different parametric control circuits and compare them.

Methodology. A generalized scheme of parametric control for asynchronous motor and its mathematical description was used for automatic selection of power converter circuits. Based on them, comparative analysis of mechanical characteristics of the motor was performed regarding changes of the parameters of the converter.

Findings. The simulation showed that the type of static mechanical properties of the asynchronous motor depends on the selected power converter circuit, the values of opening angles of the thyristors of stator and rotor switches, control mode and changes of their equivalent resistance value. Calculated mechanical characteristics of the asynchronous motor are supported by experimental results.

Originality. Methods for analytical calculations of mechanical characteristics of the asynchronous motor with various parametric control circuits were proposed.

Practical value. The proposed technique can be used for practical engineering calculations, while the mechanical properties obtained can be applied when designing asynchronous motors with parametric control.
