| Abstract [eng] |
In the classical theory the vector δ E of electromotive force induced by air–gap magnetic flux density is being resolved into the voltage drops trends in reactances ad X and aq X . The determination of these reactances are complicated and it gives great errors. Estimating an angle β (angle between the first harmonic of air–gap magnetic flux density and current vectors) it is possible the air–gap magnetic flux density electromotive force vector δ E to resolve into the voltage drops trends in resistance δ R and reactance δ X . The phase supply voltage, the armature current, the angle between vectors of current and voltage, the active and leakage reactances, of armature winding and the armature reaction reactances are need to know in order to draw the classical vector diagram. The vector diagram of synchronous reluctance motor is presented, in which active power losses in the magnetic circuit is estimated but the reactances ad X and aq X did not used. The calculated load angle θ of the motor according to the classical method changes from 43.3° till 54.1° while the direct–axis and quadrature–axis synchronous reactances d X , q X changes within ±10% limits. According to the method which is presented in this article the load angle θ changes from 54.5° till 56.7°. |
