Compare Three Phase And Six Phase Induction Motor

The equivalent electrical circuit of a dc motor is shown in figure 5.2. It can be represented by a voltage source (Va) across the coil of the armature. The electrical equivalent of the armature coil can be described by an inductance (La) in series with a resistance (Ra) in series with an induced voltage (Vc) which

Starting Current of both motors were different, when analyzed using ETAP. Starting current of Induction motor was more than that of the synchronous motor. However Induction motor is used for Stable operation in running condition [1]

There are numerous motor types available but the most common types seen in EVs are AC (alternating

The motor, it is used for a wide variety of purposes, it is used in cars, clocks, drills, fans, and electric toothbrushes (“Energy Transfer”). As one can tell, motors play an important part in daily life, people can’t go a day without using a product that uses a motor. Motor’s are normally used to spin a part of the item that the motor is in, but how does the motor spin the part that needs to be spun.

Due to the physical constraints of having to fit a motor inside the frame of a size 18”-24” wheel, Protean Electric effectively turned their in-wheel motor system inside-out. Traditionally, the design of the motor involved placing the rotor and magnets inside of the stator. However, instead of fitting the rotor inside the stator for the in-wheel motor, they have actually moved the rotor to be on the outside so that it encases the stator. The increased size and surface area of the rotor creates far more torque which allows the Protean DriveTM to boast one of the largest torque densities for any electric vehicle motor. This change also generates more available space which allows power electronics and

The subject of electric vehicles has been very popular of late. There have been many articles written, and research done, to scrutinize the on-going use of combustion vehicles while convincing the populous that electric vehicles are the wave of the future for transportation needs. Sales of electric vehicles have proven this true. Over the past five years, the number of electric vehicle sold has increased dramatically. According to the Electric Drive Transportation Association, in 2010 the number of Plug-In vehicles was only 345. The number of Plug-in vehicles -

With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor 's internals can be entirely enclosed and protected from dirt or other foreign matter.

In the first chapter of this book, the authors take some time to shortly talk about Horsepower and Torque. To begin, Torque and Horsepower are directly related to each other. In this section of the book, it explains how Horsepower is not a measurable force, but is a calculated measurement of Torque. Torque on the other hand is an actual force and can be measure through a variety of ways. It can be measured through engine, chassis, or even hand held dynamometers. Likewise, Torque is a twisting force, and is expressed in Pounds feet of Torque or Newton Meters for the metric system. Furthermore, the authors explain when the term Horsepower was first used. Moreover, James Watt, an entrepreneur and engineer who lived in the early 1700’s came up

We've all seen them before, the mysterious chunks of metal under the hoods of our cars. They start when we turn the key and take us where we want to go. But how does an engine work? Internal combustion engines are a very important part of everyday life. We use them in our cars, trucks, airplanes. boats, snowmachines, 4 wheelers, and heavy machinery. These pages will help familiarize you with the basic concepts of how an engine works, an understanding of engine output, and some information on how forced induction or "boost" increases power output.

Linear generators/motors have been around since the early 1900’s with one of the first written references being in regard to Birkeland’s Cannon, then described as a tubular motor but is more accurately described as a reluctance motor. 1

Electric motor, an electric machine works on the principle of electromagnetic induction, which transform electrical energy to mechanical energy. During motoring mode most of the electric motors operate through the interaction between motor's magnetic field and winding currents which result in generation of force within the motor. For some applications electric motors can operate in both motoring and generating or braking modes to produce electrical energy from mechanical energy. Electric motor is used as starter in large UAV’s.

Modeling of a BLDC motor can be developed in the similar manner as a three phase synchronous machine. Since its rotor is mounted with a permanent magnet, some dynamic characteristics are different. Flux linkage from the rotor is dependent upon the magnet. Therefore, saturation of magnetic flux linkage is typical for this kind of motors. As any typical three phase motors, one structure of the BLDC motor is fed by a three phase voltage source as shown in Figure 2.10. The source is not necessary to be sinusoidal. Square wave or other wave- shape can be applied as long as the peak voltage is not exceeded the maximum voltage limit of the motor. Similarly, the model of the armature winding for the BLDC motor is expressed as follows.

Permanent magnet motor was built by a permanent magnet excitation magnetic field to achieve electromechanical energy conversion device, which is electrically excited synchronous motor as a synchronous rotation speed, also known as permanent magnet synchronous motors. Magnet synchronous motor, particularly rare earth permanent magnet synchronous motor compared with the electrical excitation synchronous motor, with a compact, small size, light weight and other characteristics, and the size and structure of the permanent magnet motor in the form of flexible, it can be a variety of topological structures form. As the permanent magnet electrical motor canceled the excitation system, thereby improving the efficiency of the motor so that the

Abstract- The abstract DTC system used for controlling of Induction motor gives robust as well as gives a high dynamic performance.However it has two major drawbacks .The first one is the variation of switching frequency in accordance with the amplitude of the hysteresis bands and the motor operating speed ,also the selection of voltage vectors is not optimized inside the flux hysteresis band to
