CONTROL DEVICE OF ALTERNATING CURRENT ELECTRIC MOTOR |
摘要 |
FIELD: electricity. ^ SUBSTANCE: control device of alternating current electric motor is equipped with motor current sensor and functional converter "current sensor - load angle å", which compares the motor current as to the value considering load angle value, and produces signal of negative or positive feedback in compliance with proposed algorithm. Resultant control voltage corresponding to optimum operating mode of drive electric motor can be determined by equation V"â"=V""V"ü"å. Sign before V"ü"å of the equation is chosen in compliance with the algorithm specified in application materials. ^ EFFECT: optimisation of output parametres of electric drive in all operating modes. ^ 2 dwg |
