"It is fairly simple to construct a working motor similar to Faraday's original motor that will amaze your students. Due to safety concerns, salt water is substituted for mercury."

Hugues Duval in a Cri Cri aircraft powered by two 35 hp Electravia electric motors - Aerospace giant EADS building the little 4-motor electric Cri Cri and then right on their heels was this one pictured here that uses two 35 hp electric motors from Electravia. Both actually had their first flights back in September.

"Access4Kids with the aim of opening up entertainment, educational benefits and social media available on tablets to children with fine motor impairments. The wireless input device uses a sensor system to translate physical movements into fine-motor gestures to control a tablet."

"Uploaded by djxatlanta on Jul 13, 2010 The wheels that will touch down on Mars in 2012 are several rotations closer to spinning on the rocky trails of Mars. This video clip shows engineers in the JPL clean room where the rover is being assembled as they put all six wheels into motion for the first time. Engineers raised the rover just as a car mechanic would hoist a car to check the wheels, and started the "engine" to get the wheels rotating. The wheel mobility system has 10 motors in all-four for steering the rover and six for driving. During this test, all 10 motors ran in every direction. Each wheel spun forward and backwards. "

"The gigantic dimensions of this ultra-lightweight revolutionary airplane - capable of flying day and night without fuel - are its trademark feature. To build it, the whole team had to push back the frontiers of knowledge in materials science, energy management and the man-machine interface. Every one of its take-offs, propelled silently by its four electric motors, inspires us to consider using clean, new technologies to free our society, little by little, from dependence on fossil energy. "

"This project describes how to build a hand crank Lego usb charger with parts from a Mindstorms kit and Radio Shack. The charger uses a Lego motor to generate current which is passed through a voltage regulator and then to the usb port."

"Neurons-the electrically excitable cells that make up the brain and nervous system-first fascinated me in high school. In college, like so many other students studying the brain, I dutifully memorized the structure of the archetypal neuron. I also remember learning about a few different types of neurons with different shapes and functions: motor neurons that make muscles twitch, for example, and unique sensory neurons in the eyes and nose."

"neurons came in such a beautiful diversity of shapes. Each of these neurons has a different function, too: A. Purkinje cell B. Granule cell C. Motor neuron D. Tripolar neuron E. Pyramidal Cell F. Chandelier cell G. Spindle neuron H. Stellate cell."

"An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment, as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron."

"You aren't being propelled around the track by a motor or pulled by a hitch. The conversion of potential energy to kinetic energy is what drives the roller coaster, and all of the kinetic energy you need for the ride is present once the coaster descends the first hill.. "

a great primary site to teach students about music and instruments. The site is enchanting with it's interactive story/video platform. It invites students to take part in the story and introduces them to various "magic" instruments. As students learn, they get mouse practice (dragging dropping) for some fine motor skills; matching shapes, and identifying different types of instruments. Students also get exposed to a variety of types of music that instruments are used to create.

"Lego WeDo. This kit costs US $129.95 and comes with a motor, a motion sensor, a distance sensor and a USB-based hub. The robots built using this kit can be controlled by a variety of software platforms, including Scratch - a free and open source programming environment designed for children. Its actually quite powerful. "

The particular 'Key Points' in this article are from the "Parts and Operation of a VFD" section of the Allen Bradley VFD Training Certificate Course distance learning software.
