摘要
The mathematical models of the DC and AC motors are introduced and compared. The voltage control of motor without decoupling is considered. The flux linkage generation (rotor or stator) and electromagnetic torque are analysed. Models were unified to the transfer-function form. Mathematically proved that the transfer-function: flux linkage to the voltage in the flux axis d is always the lag element. However, the transfer-function: electromagnetic torque to voltage in the torque axis q can be the oscillatory or lag element with the difference. The propositions of the flux and torque control systems are introduced.
