Abstract. For electric vehicles (EVs), the motor is used as the power source to drive the vehicle. According to the arrangement of motors, there are four configurations: single-motor driving, dual-motor independent driving, wheel-motor driving, and dual-motor front- and rear-axle independent driving. Classification of Electric Motors Thus all application of DC motors have employed a mechanical switch or commutator to turn the terminal current, which is constant or DC, into alternating current in the armature of the machine. (Some PMDC motors have windings built into them to prevent this from happening). B- Shunt-Wound. An electric motor changes electrical energy into mechanical movement. A dynamo or an electric generator does the reverse: it changes mechanical movement into electric energy. Most electric motors work by using the force of magnetism. Electrostatic motors have also been used. Machines using electric motors include: fans, washing machines, fridges, pumps, and vacuum cleaners. Some DC electric motors can have a starting torque of % making them ideal for applications like electric cranes and trains. Three phase AC induction motors have self-starting torque, although single phase motors require auxiliary starting power.

An electric motor is an electrical machine that converts electrical energy into mechanical electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles. 1. D.C Shunt Motors: It is a constant speed the speed is required to remain almost constant from noload to full the load has to be driven at a number of speeds and any one of which is nearly constant.

The book is mostly concerned. Improving Motor and Drive System Performance: A Sourcebook for Industry was developed for the U.S. Department of Energy’s (DOE’s) Advanced Manufacturing Office (AMO) with support from the Copper Development Association (CDA).
Types of Electric Motors some form of the element carbon, serving to maintain an. Motors One of the important applications of electromagnetism is the electric motor. An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil.
The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric Motor Repair - This book takes you through the functions and repairs of the different types of electric motors, generators, and controls.

If an existing motor is being replaced it would have been supplied with a manufacter's nameplate offering all the details about the original motor necessary for offering a.
EV Power Systems (Motors and controllers) The power system of an electric vehicle consists of just two components: the motor that provides the power and the controller that controls the application of this power.
In comparison, the power system of gasoline-powered vehicles consists of a number of components, such as the. Sizing Electric Motor for Motion Control General To size a electric motor for a particular drive application the designer must first analyze the mechanics of the drive application.
Start and Running Torque Requirements, Calculations for Electric Motors The starting torque is dependant on the number of times anelectric motor will have to start. There are several electric motors that can be considered for traction: Induction motor, Surface-mounted permanent magnet (PM) motor, Internal PM motor, PM synchronous reluctance motor, and.
Switched reluctance motor. Some of these motors are suitable for variable-speed traction drive, and some need to be modified to suit the requirements. A DC motor is an electric motor that runs on direct current power. In an electric motor, the operation is dependent upon simple electromagnetism.
A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field, it will encounter a force proportional to the current in the conductor and to the strength of the external magnetic field. This drive system is widely used in large number of industrial and domestic applications like factories, transportation systems, textile mills, fans, pumps, motors, robots etc.

Chapter 4 of the National Electrical Code (NEC), Equipment for General Use, contains 22 articles. Some of the articles include provisions pertaining to switches, receptacles, switchboards and panelboards, industrial control panels, luminaires, appliances, air-conditioning and refrigeration equipment, and transformers.
One of the most referenced articles in Chapter 4 is ArticleMotors. 2.a) Parts of an electric motor: There are many kinds of electric motors but in general they have some similar parts.
Each motor has a stator, which may be a permanent magnet (as shown in the 'universal motor' above) or wound insulted wires (an electromagnet like in the photo above-right).The rotor sits the middle (most of the time), and is subject to the magnetic field created by the stator.
proportional 2to I so it gives the highest torque per current ratio over all other dc motors. It is therefore used in starter motors of cars and elevator motors (p. Chapman, 4e, McGrow Hill). Permanent Magnet (PMDC) motors: The stator is a permanent magnet, so the motor is smaller in size.
MOTORS Electric motors, both ac and dc types, come in many shapes and sizes. Some are standardized versions for general-purpose applications. Others are intended for specific tasks.
