Problems of power quality have been increasingly concerned by the researchers, as the domestic appliances we are usually used are single-phase load, which mainly causes the unbalance of three-phase voltage of power supply. If the induction motor is supplied by three-phase unbalanced voltage, the currents, active and reactive power, efficiency, and losses are affected as the negative-sequence current appears, this paper is emphasized on the induction motor’s characteristics when its’ power supply is three-phase unbalanced voltage by experimental research.

Power Frequency

In the countryside of China, the main power supply mode is 220V single-phase power, which affects the widely application of three-phase agricultural appliances. What’s more, it means a block to the development of modern agriculture. However, frequency converter technique research is focused on three-phase high power frequency conversion technology at present, and there are very few achievements on the agricultural low power single-phrase frequency conversion research. In this paper, considering the difficulty of widely application of agricultural low power three-phase AC motor because it is not easy to obtain the three-phase power supply, a three-phase AC frequency conversion system under the condition of agricultural 220V single-phase AC power is designed, which can achieve the stepless regulation of the voltage amplitude and guarantee the widely use of the three-phase AC motor under the condition of agricultural 220V singlephase AC power. The experimental results show that the system can output the controlled three-phase AC power when the input is 220V single-phase AC power. And the rational design of the system hardware also provides the technical support for the application of agricultural low power frequency conversion.

The Relationship

On the basis of the method of symmetric components, an analytical method is proposed for calculating the coefficients that determine the relationship between the components of the positive and negative sequences of the parameters of the operating mode of an induction motor and the parameters of its power supply for some circuits for the inclusion of voltage-controlled three-phase induction motors with phase-shifting capacitors powered by a single-phase network. On the basis of this technique, the optimal parameters of phase-shifting capacitors can be determined and rational schemes for connecting three-phase induction motors to a single-phase network can be selected.

Motor Design

A 1-phase induction motor usually has a complicated windings design which compares to polyphase induction motor. In addition, a large capacitor start is required to operate the motor. It is an expensive way to operate the motor if it compare to polyphase induction motor. So, a new innovation method is required to make the motor more simple and cheaper. This research is purposed to study a new winding design for a single-phase capacitor motor. Winding design of the motor was conducted to a simple winding design like a 4-phase induction motor that has four identical windings. The comparator motor that use in this study was a Three-phase induction motor with data 1400 RPM, 1.5 HP, 50Hz, 380/220V, Y/Δ, 2.74/4.7A, 4 poles, that had the same current rating which the proposed method. The result showed that the motor design on this proposed method could be operated at 88.18 % power rating with power factor close to unity.
