To ensure the starting performance of the single-phase induction motor with three parallel-connected windings, the transient performances and starting methods are studied in this paper. At first, the transient mathematical model of the motor is established according to the electromagnetic relations, and the simulation analysis is performed. Then two starting methods are proposed and studied. The first...

In order to study the effect of removing the filter capacitor in the rectifier circuit on the steady-state performances of the permanent magnet direct current motor, simulation analysis and experimental research were accomplished according to a rated voltage 300V DC, 180W, 2-poles permanent magnet direct current motor. The motor was fed by three different methods. The first method is to use standard...
A novel single-phase permanent magnet synchronous motor (PMSM) which employs three winding in series connection with two capacitors is presented. This paper describes the design of the novel PMSM based on the parameters of the three-phase PMSM with same output power. Performance equations are derived using the method of symmetrical components and equivalent circuit for this motor is proposed to predict...
Because of the increasing pressure for improved the efficiency single-phase motor, a novel single-phase induction motor with three winding in series and two capacitors has been provided to be capable of high efficiency demand. This paper introduces the basic structure and operational principle of the new type motor. A voltage source driving complex finite element model for the novel high efficiency...
This paper presents a novel energy efficient single-phase induction motor with three series-connected windings and two capacitors. By suitable selection of capacitors, the currents in three windings are approximately symmetrical, and thus, the motor can operate approximately symmetrically from single-phase supply. Based on the symmetrical components method, the condition for balanced operation is...
