Kot skupna vrsta motorja igrajo enofazni AC mototorji pomembno vlogo v panogah, gospodinjskih aparatih in drugih poljih . Razumevanje razlik med različnimi vrstami enofaznih izmeničnih motorjev je ključnega pomena za izbiro pravega motorja .
Enofazni AC mototorji so v glavnem razdeljeni na razcepljene faze, kondenzatorja in zasenčenih vrst .
Split-phase motors use capacitors or resistors to divide single-phase AC into two currents with a certain phase difference, which are respectively passed into the main winding and the auxiliary winding to generate a rotating magnetic field. This type of motor has a small starting torque and is suitable for occasions with light loads and low requirements for starting performance, such as some small fans.
Capacitor motors can be divided into capacitor starting type and capacitor running type. When the capacitor starting type is started, the capacitor is connected in series with the auxiliary winding to provide a large starting torque, and the capacitor is removed after starting. It is often used in equipment that requires a large starting torque, such as small air compressors, woodworking machinery, itd . Vrsta kondenzatorja, ki deluje, je, da je kondenzator zaporedno povezan s pomožnim navijilom med celotnim postopkom delovanja, kar lahko izboljša delovno zmogljivost in faktor moči motorja . Primerno je za opremo, ki dolgo časa deluje in ima relativno stabilno obremenitev .
The shaded pole motor has a simple structure and is cheap. It is a motor in which a part of the magnetic poles on the stator core are "covered" by a short-circuit ring, and an induced electromotive force is generated through the short-circuit ring, thereby forming a rotating magnetic field. The starting torque and efficiency of the shaded pole motor are relatively low, but the operation is stable and Hrup je nizek . Pogosto se uporablja v priložnostih, kadar zahteve za izhodiščni navora niso visoke, vendar so potrebe po hrupu visoke, kot so majhni električni ventilatorji, električni igrače itd. .
Različne vrste enofaznih izmeničnih motorjev imajo očitne razlike v zagonu učinkovitosti, učinkovitosti delovanja, veljavnih obremenitvah itd.
