AC Motors vs DC Motors DC Motors Prof. Dr. M. Zahurul Haq zahurul@me.buet.ac.bd http://teacher.buet.ac.bd/zahurul/ Department of Mechanical Engineering Bangladesh University of Engineering & Technology e316.eps ME 475: Mechatronics AC motors are smaller in size‚ reliable and less costly. AC motors run at fixed speed set by the line frequency. Easy speed‚ torque & direction controls in DC motors. DC motors are generally operate at lower voltages which makes these easier to interface with control

ELECTRIC MOTOR CONTROLS Once the proper motor is selected‚ understanding the many various control devices available and their uses and limitations becomes an important part related to reliable operation and protection of the motor and the personnel using the motor. Motor Control Topics There are four major motor control topics or categories to consider. Each of these has several subcategories and sometimes the subcategories overlap to some extent. Certain pieces of motor control equipment can accomplish

SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include but

ultrasonic motor INTRODUCTION All of us know that motor is a machine which produces or imparts motion‚ or in detail it is an arrangement of coils and magnets that converts electric energy into mechanical energy and ultrasonic motors are the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque

Servo Motors Servo motors are great little components that are often used in radio-controlled cars to control steering and the control surfaces on model aircraft. They come in a variety of sizes for different types of applications‚ and their wide use in models makes them relatively inexpensive. Unlike normal motors‚ they do not rotate continuously; rather‚ you set them to a particular angle using a PWM signal

Strategy is the key to success. Tesla Motors has separated from the competition in the automobile industry. The question is how and why It all comes to the type of strategy the company has implemented and what makes them different form their competitors. In todays global economy having a unique strategy on how to market to customers is very important. The customer needs will always change due to changes in their environment. This is why it is important to develop a strategy that fits the needs of
