Single-phase Induction Motors | AC Motors | Electronics Feb 12, 2015Single Coil of a Single Phase Motor The single coil of a single-phase induction motor does not produce a rotating magnetic field, but a pulsating field reaching maximum intensity at 0° and 180° electrical. Single-phase stator produces a nonrotating, pulsating magnetic fieldAuthor: Tony R. KuphaldtPermanent-Split Capacitor MotorOne way to solve the single phase problem is to build a 2-phase motor, deriving 2-phase power from single phase. This requires a motor with two win..Capacitor-Start Induction MotorIn Figure below a larger capacitor may be used to start a single phase induction motor via the auxiliary winding if it is switched out by a centrif..Capacitor-Run Motor Induction MotorA variation of the capacitor-start motor (Figure below) is to start the motor with a relatively large capacitor for high starting torque, but leave..Resistance Split-Phase Motor Induction MotorIf an auxiliary winding of much fewer turns of smaller wire is placed at 90o electrical to the main winding, it can start a single phase induction..Nola Power Factor CorrrectorFrank Nola of NASA proposed a power factor corrector for improving the efficiency of AC induction motors in the mid 1970’s. It is based on the prem..
