The Tabletop Explainer is an intermittent educational vlog presenting answers to viewer questions, brief science lessons, and ideas for teachers and students. It is a feature of my blog "Tilts at Windmils" which can be found at www.davidcolarusso.com Download the background music, Time to Funk by Trafic de Blues: www.jamendo.com ======================== TROUBLESHOOTING & FAQ ======================== First, it's important to understand the context of the "Build Your Own Motor..." video. It's a demonstration aimed at solidifying the ideas presented in two earlier videos. If you haven't already, you should watch the whole set: 1) What is the magnetic field? www.youtube.com 2) Electricity & Magnetism Hand Rules (part one) www.youtube.com 3) How to build a simple electric motor, plus how it works. www.youtube.com The main idea here is that charges moving through a magnetic field experience a "push" perpendicular to the direction of their motion. This force is also dependent upon the direction of the magnetic field. The fact that the wire is stripped on only one side alternates the current from "on" to "off" every half rotation. So halfway through the spin, the ring coasts through until it gets current again receiving a "kick." It's a poor man's commutator. The particulars of this kick/force are discussed in the second video. Armed with the knowledge from the above videos, you should be able to troubleshoot most of the problems that arise. The key is to make sure you understand <b>...</b>

Test to see how long it takes a generator to run an electric motor. The current from the batteries goes to the motor that attached to the generator shaft refers the current to the engine and everything goes as long as it doesn't decay for electrical load and friction..My video doesn't prove anything of concrete. It's only for demonstration purposes and curiosity.

he forces on the wire segments of the current loop in an electric motor depends upon the geometry of the loop (relative to the magnetic field) as well as the direction of the current. This animation illustrates those forces and the role of the commutator in switching the current direction so that torque on the loop continues to keep the loop spinning.

The rest of the energy is lost to engine and drive line inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous.

A motor made only by a copper wire and a neodymium magnet. It uses one AAA battery but it can be done with AA one too. It's a simple motor, but unfortunately is not an efficient one, the battery drains quickly and heats up. Warning: Be careful if you try to do this, the copper wire can get very hot and burn your fingers. Be sure that the wire can move freely and not touches battery poles being stuck..

Scientists have downsized the electric motor to the molecular level. That is, they've created an electrical motor that's the size of a nanometer. About 60000 of them equal the width of a human hair. The molecular motor is a breakthrough that could lead to new types of electrical circuitry, according to Charles Sykes, an associate professor of chemistry at Tufts University in Massachusetts.

Siemens VDO engineers are working on plans to integrate the drivetrain, steering, shock absorbers and brakes directly into the wheels of future cars. This concept, called eCorner, is the basis for the ecological "Drive-by-Wire" automobiles, which will become a common sight on roads in 15 years. eCorner replaces the conventional wheel suspension with hydraulic shock absorbers, mechanical steering, hydraulic brakes and, above all, conventional internal combustion engines. For car owners, eCorner translates into improved fuel mileage, more safety and greater convenience. eCorner provides designers with all new freedom to create future cars with an electric drivetrain and electronic control.

CEO William Rankin and employees of UQM Technologies give Susan McGinnis a tour of their assembly plant in Longmont, CO. Rankin shows Susan the assembly line where the motors are made. He points out a rotor, the spinning part inside the motor, which is mounted in a water-cooled housing. Parts for the motors are sourced worldwide and after the motors are assembled, they are shipped to customers. Total employment of the company is currently 78, most of whom are engineers. Rankin says all of the company's positions are considered "green jobs." The line is capable of producing a motor every six minutes, 80 per day, 20000 per year. Susan interviews a worker who is assembling a component and sealing it so it will be watertight. Another worker shows Susan a shaft and rotor assembly. He is applying a fiberglass band with an epoxy resin that keeps the magnets in the rotor from coming loose. Afterward, the assembly will be baked to create a strong bond. It's one of the early parts of the assembly process. The employee is an engineer who develops the company's assembly processes and helps design the equipment that operators will eventually use to make the motors in mass assembly. He says he came to UQM from the aerospace and defense industry. He believes the "green industry" of electric motor manufacturing has a better future for him. Another worker tells Susan her history with the company as we watch two other workers assembling circuit boards. Susan interviews a worker who shows <b>...</b>

Here's how to make a simple electric motor - the copper wire is reclaimed from an inductor component pulled from the PSU of a dead inkjet printer, the magnets are taken from a broken computer hard drive, the rest is just bits and pieces of timber and odd nails and screws. The captions describing construction have deliberately been kept in quick-fire form, to keep the video short - further details on making a motor like this one may be found on the website. A simple motor like this one could be used as part of a school science project - as the principles employed here are the basis for most of the small electric motors found in so many commonplace objects today. The simplicity of design of a single-coil motor such as this makes it an ideal springboard for exploration and discussion of fields, forces and the physical laws.
