Speed Control Of Dc Motor

Using an electric motor, an experiment was performed to test the efficiency of the motor when the mass being lifted was increased in increments of ten grams. As the mass increased by each increment of ten grams, the motor efficiency decreased by an average of 7.439%. Our results were found by using the equation: efficiency=gain in potential differenceelectrical energy used Therefore, this inverse relationship proved mass affects the efficiency of electric motors.

TM4, the industrial partner, is a leading manufacturer and supplier of traction motors and drives for electric vehicle industry in Canada. As a drive manufacturer, they always aim to provide solution which is energy efficient with small footprint. In order to achieve this, they always look for alternative software and hardware solutions. Software modifications, which may improve the system performance in comparison to their existing drive control strategy without increasing the size of the system, are always sought after for continuous improvement of their system. In this regards, the internship is relevant to them for exploring alternative control strategies.

Due to the rising awareness of using green energy, applications of electric motors are expanding widely in motor industry, and different types of electric motors are used in all kinds of applications, such as, the public transportation, electric vehicles, and mechanical fans. Because of the variety of working conditions in distinct application usages, engineers are developing various control theories to meet specific requirements based on different types of power system and motor.

B. Series hybrid’s only have electric motors to provide propulsion while maintaining an exceptionally high power to weight ratio providing enough torque over a broad range of speeds.

Consider vehicles as well as hustling? Verify on your own in NN. We have one of the most useful product scientific research electric motor in the course, indicating that every little thing functions the method it does reality be informed. Recorded specifications, dyno representations, furnishing lays out and also drove race sizes will certainly aid you place your understanding to make use of.

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

Currie scooters are known for their patented unique electro-drive propulsion systems that provide efficient performance in all situations.

During the 4-month semester for Level 3 Drivetrains we reviewed in detail the operations for Torque converters, Planetary gears, Inputs and Outputs for Allison World Transmissions, and Power flow for Allison 1000/2000 series transmissions. In this essay, I will be revising and explaining how these systems work and what operations they serve.

Brushless permanent magnet DC motors are being manufactured and used increasingly in everything from home appliances to automobiles due to their inherent advantages. The merits of these motors could be enhanced further according to another design approach method which alters the typically used winding parts for low to medium power range motors. This paper deals with the high power brushless DC motor used for traction in a 48 V golf cart system.

* The design of a diesel engine requires a much heavier construction. This heavy engine, combined with the high amount of compression it uses to ignite fuel, means that the engine runs at a much lower rate of revolutions per minute (RPM). Because it runs at a lower RPM rate, the engine needs much less force to rotate the machinery that moves a diesel vehicle. Because the engine can move machinery with much less force than a gasoline engine, it is much better at making a towed object start moving.

Economically, petroleum fuel prices have escalated in the past, which make the use of the electrical controlled vehicle a great alternative to manage the cost issues. Therefore, this research proposal focuses on Electrical Vehicle technology.

In today’s motorized life , It’s difficult to live without motor (Engines) and the main source of it’s input power is fossil fuels & partly electric power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with the fuels.

The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed.

Abstract— The three-phase squirrel cage induction motor is the most widely used motor type in the industry because of its good self-starting capability, simple and rugged structure, low cost and reliability. In spite of this popularity, the induction motor has two basic limitations: (i) The standard motor is not a true constant-speed machine, its full-load slip varies from less than 1% (in high-horsepower motors) to more than 5% (in fractional-horsepower motors), and (ii) It is not inherently capable of providing variable-speed operation. The limitations of induction motor can be solved through the use of adjustable speed control method of induction machine. In this paper, various method of speed control of induction motor drive are presented.
