Motori à Induzione Monofase
The single-phase motor operates beneath the same principle as the polyphase electric motor, except that the rotating magnetic field effect generated by the stator will not exist until running rpm is reached. Since no starting torque is obtainable, a design system is included to begin the motor. These are the various designations:
Curve di Coppia-Velocità di Diversi Motori à Induzione Monofase
Shaded-pole: Have only one main winding and no start winding. This configuration causes a change of the used magnetic field in romantic relationship to the rotor, creating stating torque. Applications include followers and small appliances.
pignoni Split-Phase (motore di inizio à induzione)
Has two units of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and change the magnetic field of the stator, inducing beginning torque. Applications include small grinders, small enthusiasts, and blowers.
The most typical single-phase motor found in industrial applications. It is a modified split-phase motor with a capacitor in series with the beginning winding to supply a start boost. App include small conveyors, large blowers, pumps, and direct-drives.
Condensatore Split Permanente (PSC)
Uses identical main and auxiliary windings with a capacitor to provide starting torque. They will be the most reliable single-phase motor because no centrifugal starting switch is required. Applications include followers and pumps in HVAC and refrigeration industries.
