MODELING OF ELECTRIC MACHINES FOR AUTOMOTIVE APPLICATIONS USING EFFICIENCY MAPS S. M. Lukic and A. Emado Illinois Institute of Technology Abstract: In most industrial applications of motor drives‚ motors operate at one or a few predefued operating points. However in propulsion applications‚ the motor is used over the entire torqudspeed range. Therefore‚ the motor has to be studied at all possible torqudspeed combinations within the motor operating envelope. Efficiency maps are a convenient way

Dominion Motors Case Analysis What‚ precisely‚ is the problem here? The problem is that DMC ’s largest consumer of oil well pumping motors has ranked them the #3 supplier‚ and not only could this impact purchasing from this customer (Hamilton)‚ other smaller companies follow this large company for their purchasing decisions‚ so that they get the benefit of copying their R&D decisions. What are the causes of the problem? Power companies implemented a graduated monthly base charge per HP

Speed Control of Dc Motor Using Fuzzy Logic Technique 1 1‚ 2‚ 3 J. N. Rai‚ 2Mayank Singhal‚ 3MayankNandwani Department of Electrical Engineering‚ Delhi Technological University Abstract:This project uses FUZZY LOGIC TECHNIQUE in estimating speed and controlling it for DC motor. The rotor speed of the dc motor can be made to follow an arbitrarily selected trajectory. The purpose is to achieve accurate trajectory control of the speed of DC Motor‚ especially when the motor and load parameters

Battery Powered Motor Problem: Will changing the polarity of a battery powered motor change the direction the motor spins? Hypothesis: If the polarity is changed on a battery motor‚ I think it will change the direction the motor spins. I think it will act like reverse button. Methods: I. Connect a battery powered motor to a battery using a simple circuit a. Check that the negative of the battery is connected to the negative of the motor b. Check the

Principles of operation In any electric motor‚ operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field‚ it will experience a force proportional to the current in the conductor‚ and to the strength of the external magnetic field. As you are well aware of from playing with magnets as a kid‚ opposite (North and South) polarities attract‚ while like polarities (North and North‚ South and South) repel

READ MOREBrushless DC Motors are an important class of highly efficient electric motors. They are most frequently used in electric vehicles because of their high efficiency and high power density. They are also present in the small DC fans used in power supplies and CPU coolers. In order to discuss the Brushless DC Motor it is important to first have a basic understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor (the
