Abstract:
This paper presents the design of a line-start permanent magnet (LSPM) motor by modifying a commercial premium efficiency cage induction motor (IM) for cooling fan applications. Two-dimensional transient finite element (FE) analysis is applied to both IM and LSPM motor to compare their starting and synchronization performance for fan-type load. It clearly shows that the LSPM motor has better efficiency and power factor than that of IM at steady-state. However, the transient starting performance of the LSPM compares less favorably with that of the IM.Keywords:

The electric vehicle is a key new transportation technology to reduce the pollution and to reduce use of fossil fuel. As the era of cheap fuel is coming to end, so the focus on the electric vehicle in India is increasing. In this paper the study of different forces acting on the vehicle are studied and the power requirement of the vehicle is evaluated. The survey of different motors presently used and there comparison is given. And according to the power requirement for electric vehicle size and other parameters of three phase induction motor is calculated. This motor is validated in MATLAB Simulink. Also a PWM inverter is design to supply the Motor and v/f speed control technique is used. To control the speed of deep-bar rotor induction motor a close loop system is used by comparing the speed of motor with set speed the frequency of supply is varied. Also a vehicle dynamics model is develop to validate the system.

This study compares Direct Torque Flux Control (DTFC) performance of a three-phase Induction Motor (IM) and its equal Line-Start Permanent Magnet Synchronous Motor (LSPMSM). Simulation results of line-starting DTFC method of an IM and its equal LSPMSM (for both normal and voltage sag conditions) is compared and analyzed. In addition, field weakening region is evaluated. The advantages of the discussed control strategy over line-starting are also investigated for LSPMSM.

This paper presents an in-depth comparative analysis of the variable speed drive (VSD) performance between an IEC frame size 90 four-pole three-phase induction motor (IM) and the equal line-start interior permanent magnet synchronous motor (LSIPMSM). Employing measurement data from no-load tests, load tests, and temperature-rise tests of the aforementioned motors and different cage materials as well, the motors' no-load and load characteristics are first examined in detail and then the drives' characteristics are analyzed in open-loop volts per hertz ( V / f ) control by using the same voltage-source inverter and the aforementioned IM or LSIPMSM in both constant torque and constant power operation. It has been established that particularly the motors' current and power factor characteristics have distinct impact on the consequent VSD performance in terms of loss and efficiency. Furthermore, it has been shown that the lower loss of the LSIPMSM enables a significant increase of the VSD's constant power range.

This paper presents an explicit comparison of the three-phase line-start permanent-magnet synchronous (LSPM) motor with the squirrel-cage induction motor (IM). It investigates the effect of number of rotor bars on the performance of the motors by considering two alternative options including 32 and 45 rotor bars. Finite-element analysis is utilized for design and performance prediction of the studied motors. Both steady-state and dynamic responses of the motors under no-load, constant load, fan load, and step load are investigated. The simulation results confirm that the LSPM motor with 32 rotor bars can remain stable at constant speed when operating in overloaded and variable voltage conditions. The LSPM motor has advantages of high efficiency and high power factor while IM has superior dynamic performance.

Induction motor is one type of electric machine that is most often used. The use of induction motors starts from the needs of resident customers to large industries. However, the existence of an induction motor in the electric power system can interfere the power quality, especially large capacity induction motors. The cause of the disturbance is the starting current of the induction motor. Synchronous generator as power supply is also affected by the starting process. When the starting condition, the induction motor requires a lot of power to start its initial rotation. The moment of inertia in the induction motor increases the load starting torque. In addition, synchronous generators also have to produce greater power to meet the needs of starting an induction motor. This paper aims to analyze the effect of starting induction motor on the power quality of synchronous generator. In the test method using induction motor with capacity of 100 kW, 300 kW, 700 kW, and 1 MW. Each induction motor takes parameter data such as starting current, motor torque, motor speed, motor voltage, active power and reactive power consumption. Likewise with the disturbed quality of synchronous generator power, then the parameters that experience disturbances are taken such as current, voltage, power factor, active power and reactive power generated by synchronous generators. Furthermore, all the results of these experiments are compared between induction motors with different power capacities to the power quality of synchronous generators.

본 논문에서는 전력에너지를 사용하는 산업체의 전동기용량이 점차 증가하고 있다. 전동기는 기동시 기동전류로 전압강하가 발생한다. 이 기동전류가 전력계통에서 대형 전동기 기동 시 전압강하로 기동이 어려워 인접한 전력계통에 나쁜 영향을 미치게 된다. 또한 전동기는 부하의 크기에 따라 토크를 내는 것으로 토크의 크기에 따라 속도가 변하고 속도는 전동기 기동에 중요하다. 일반적으로 변압기나 비상발전기로부터 전동기까지의 거리가 짧으며 전동기용량이 작아 기동에 대한 어려움이 없으나 산업설비 등에 많이 이용되는 대용량 전동기의 기동특성에 대한 이론과 실제의 운전특성을 측정 분석하였다. 따라서 이번 연구는 전동기 기동 시 속도와 토크에 관계와 대용량 전동기 기동을 위한 분석과 전동기 기동 해석에 대해 연구하였다.

In addition to that the motor torque according to the load depending on the size of the rotation speed is changed to a motor start-up speed is important. However, the distance to the emergency generator transformers or motors from the motor capacity is smaller but short and difficult to maneuver the theory and practice of the operating characteristics of the starting characteristics of the motor used a lot of large industrial plants were measured and analyzed. Therefore, this study investigated the motor starting Analysis and interpretation for the relationship with the large motor starting torque and speed during motor starting.
