Three phase induction is the most common motor and is widely used in various industrial equipment because of all the advantages. To get the best performance, the quality of powersupply of induction motors needs to be maintained. One of the problems that arise in power quality is under voltage or over voltage. In this study the calculation and analysis of efficiency using the segregated loss method of 3 phase induction motors connected to stars and delta on the under voltage and over voltage conditions of the rating voltage, and at the rating voltage, the motor used is a 3 Phase 1 HP 4 pole induction motor with voltage rating of 380 volts. The method used is the segregated loss method, this method is a method to get the value of the efficiency of the induction motor by finding and separating the value of loss and loss, the method used refers to IEEE 112. Simulation using PSIM software as a hypothesis and comparison, variables taken are speed, current, inter-phase voltage and input power. Based on the results of calculations from all experiments show that the induction motor will produce better efficiency at loads approaching its capacity, and under voltage and over voltage conditions affect the efficiency value with a small difference in each change in voltage conditions. Efficiency values in all star motor voltage conditions range between 44% - 52% and in delta connection motor ranges between 39% - 42%. Simulations carried out using PSIM software produce higher efficiency than the test results with a range of values of 67% -78%, where the value is calculated from the simulation results and ignoring core losses.

A three-phase induction motor will continue to operate when a disturbance of some sort causes the source voltages of the motor to become unbalanced. When an induction motor is operated at unbalanced voltage supply the performance characteristics like efficiency, power factor, input power, output power and losses are affected.  The single-phasing occurs when one phase fails as a result of a fuse blowing, protective device opening on one phase of the motor, open phase on one terminal of the motor or other causes. This paper will analyze the operation of a 3-phase induction motor under normal balanced source voltages first, then under single phasing experimentally in order to follow a comparative approach.

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.

This article presents the effectiveness of bispectrum analysis for the detection of the rotor unbalance of an induction motor supplied by the mains and a frequency converter. Two diagnostic signals were analyzed, as well as the stator current and mechanical vibrations of the tested motors. The experimental tests were realized for two low-power induction motors, with one and two pole pairs, respectively. The unbalance was modeled using a test mass mounted on a specially prepared disc and directly on the rotor and the influence of this unbalance location was tested and discussed. The results of the bispectrum analysis are compared with results of Fourier transform and the effectiveness of unbalance detection are discussed and compared. The influence of the registration time of the analyzed signal on the quality of fault symptom analyses using both transforms was also tested. It is shown that the bispectrum analysis provides an increased number of fault symptoms in comparison with the classical spectral analysis as well as it is not sensitive to a shorter registration time of the diagnostic signals.

Abstract— An induction motors  (IM) in many industries is used because it has several advantages, such as a very simple and strong construction, the price is relatively cheap, has good efficiency, power factor is quite good, and maintenance is easier. Besides the advantages of induction motors also have disadvantages, one disadvantage of induction motors is not being able to maintain a constant speed when there is a change in load. If the load changes, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor presented in this study is the regulation of an induction motor using a carrier based PWM (CBPWM) inverter with the field oriented control  (FOC) technique. The estimation of rotor rotation, torque and flux is done by carrier- based PWM  technique which is given input voltage and stator current. To achieve the desired flux and torque, estimation is used as feedback in the control system. In this study, it will be simulated the induction motor speed regulation with a carrier base-based inverter using Matlab. The results obtained through simulation show the length of time to reach the reference speed for speeds of 1500 rpm and 1450 rpm is around 0.45 seconds. And THD  average 2,675%.
