Background technology
The ultimate principle of threephase asynchronous is: the rotating speed of three-phase asynchronous motor rotor is lower than the rotating speed of rotating magnetic field, rotor windings is induced electromotive force and electric current because there is relative motion between magnetic field, and produce electromagnetic torque with magnetic field interaction, realize energy conversion.
Compared with monopole asynchronous motor, threephase asynchronous runnability is good, and can save various material.By the difference of rotor structure, threephase asynchronous can be divided into cage and Wound-rotor type two kinds.The Induction Motor Structure of cage rotor is simple, reliable, lightweight, low price, is widely used, and its major defect is speed governing difficulty.The rotor of wound three-phase asynchronous motor is the same with stator to be also provided with three-phase windings and to be connected with outside rheostat by slip ring, brush.Standardsizing rheostat resistance can improve the starting performance of motor and regulate the rotating speed of motor.
Three-Phase Asynchronous is: when the threephase stator winding (each difference 120 degree of electrical angles) of motor, after passing into three-phase symmetrical alternating current, by generation rotating magnetic field, this rotating magnetic field cutting rotor winding, thus in rotor windings, produce induction current (rotor windings is close access), the rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating magnetic field, thus electromagnetic torque is formed on machine shaft, drive motor rotates, and motor sense of rotation is identical with rotating magnetic field direction.
