If you’re Google CEO and co-founder Larry Page‚ though‚ you already know how you want your money to live on after you’re gone: support innovators like Tesla CEO Elon Musk. That’s what Page said at the TED conference in Vancouver‚ Canada this week‚ anyway‚ adding that the already-wealthy Musk is worthy of the Page billions because he’s one of the people who can change the world.

Introduction An automobile or motor car is a wheeled motor vehicle for transporting passengers; which also carries its own engine or motor. Most definitions of the term specify automobiles are designed to run primarily on roads‚ to have . seating for one to eight people‚ to typically have four wheels‚ and to be constructed principally for the transport of people rather than goods. Automobile comes via the French language‚ from the Greek auto [self] and mobiles [moving]; meaning a vehicle that

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

May be 20 years‚ or 30 years later? We still don’t know that yet‚ but one thing we do know about is many car companies are trying to find different energy to replace gasoline. In currently‚ Electronic car is best much type that fit our need at this moment. There is a very successful Electronic car company called Tesla‚ who

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
