A linear induction motor is basically what is referred to by experts as a “rotating squirrel cage” induction motor. The difference is that the motor is opened out flat. Instead of producing rotary torque from a cylindrical machine it produces linear force from a flat machine. The shape and the way it produces motion is changed, however it is still the same as its cylindrical counterpart. There are no moving parts, however and most experts don’t like that. It does have a silent operation and reduced maintenance as well as a compact size, which appeals many engineers. There is also a universal agreement that it has an ease of control and installation. These are all important considerations when thinking about what type of device you want to create. The linear induction motor thrusts ratio varies depending mainly on the size and rating. Speeds of the linear induction motor vary from zero to many meters per second. Speed can be controlled. Stopping, starting and reversing are all easy. Linear induction motors are improving constantly and with improved control, lower life cycle cost, reduced maintenance and higher performance they are becoming the choice of the experts. Linear motors are simple to control and easy to use. They have a fast response and high acceleration. Their speed is not dependant on contact friction so it is easier to pick up speed quickly.

Stepper motors are a special kind of motor that moves in discrete steps. When one set of windings is energized the motor moves a step in one direction and when another set of windings is energized the motor moves a step in the other direction. The advantage of stepper motors that the position of the motor is “known”. Zero position can be determined, if the original position is known.

Stepping motors come in a wide range of angular resolution and the coarsest motors typically turn 90 degrees per step. High resolution permanent magnet motors are only able to handle about 18 degrees less than that. With the right controller stepper motors can be run in half-steps, which is amazing.

A linear induction motor is made up of an inductor which is made of individual cores with a concentrated polyphase. Linear motors can be directly substituted for ball screw drives, hydraulic drives, pneumatic drives, or cam drives.

The main complaint about the stepper motor is that it usually draws more power than a standard DC motor and maneuvering is also difficult.

History:

Martial arts boomed during the early 1970s and interest was greatly increased by their emphasis on competition fighting. Chinese styles of fighting began to take a more westernised form in the UK, and even more so in the United States, where the first real freestyle systems were beginning to be created. Indeed, many people claim that Kick boxing originated in the US during the 1970s. This, they say, was due to various American Karate practitioners becoming frustrated with the limitations of tournament competitive scoring. While Karate and the other disciplines were viewed as being entrenched with theories and set kata, and were performed in a controlled environment, practitioners wanted to see how effective their moves would be in a more realistic environment. Great emphasis began to be placed on specialised techniques, such as kicks and punches, being delivered with full force. Although full contact Karate was already established, concerns were expressed for the safety of competitors.

There is a close affinity between Kick boxing and Muay Thai. While it is believed that the Americans had created this concept in their attempt to find a sport that could refine full contact competition, it is believed that the development of Kick boxing was borne out of the World Kick boxing Association finding common ground between Eastern and Western fighting cultures.

It is also believed that Joe Cawley, Don and Judy Quinn, along with Howard Hansen, a Shorin ryn Karate black belt, were the initial promoters of Kick boxing and worked together for improved recognition. Hansen took Kick boxing a stage further by introducing fights in a boxing ring rather than the usual Karate tournament bouts. He became known as a ring matchmaker, staging a variety of successful events with stars such as Bill “Superfoot” Wallis.

A Murder Mystery Puzzle for You to Solve
Anybody who has visited my website at Motivation & Self Esteem for Success or has read any of the many articles I have written will realise what a proponent I am of reading books and educating yourself. If you want to become successful at anything you simply must do this, in my opinion.
However, not everything you learn and/or read is of equal value. As the world?s store of information becomes exponentially greater, almost by the minute, you must learn to become more and more discerning about what you read and believe.
With this in mind, I believe you need to understand five basic things:

- Find out what you are interested in,
- Look for information on subjects of interest,
- Search for constants to confirm your understanding,
- Filter out needless information and garbage from real knowledge,
- Act only on what you believe to be the truth.

To demonstrate the above points I have devised a little mystery for you. I hope you will find this not only a stimulating exercise but also a bit of fun.
Listed below is a set of 16 clues to a murder investigation involving the occupants of five consecutive houses. They are all you need to solve the mystery of ?Who Killed Who.?
The ?Who Killed Who? Murder Mystery Clues:

- The Motivator plays bowls on Saturday.
- When facing the houses, the house with the blue roof is immediately to the right of the house with the grey roof.
- The man in the middle house plays golf twice a week.
- The woman in the house with the blue roof is a hockey player.
- The Scientist lives in the first house, near the cheesecake shop.
- The person who drives a Jaguar lives next to the man with the Dalmatian.
- The person who lives in the house with the red roof drives a Renault.
- The Scientist lives in the house next to the house with the green roof.
- The Accountant?s house has a Volkswagen parked in the driveway.
- The man who drives the Lexus owns a Shitzhu.
- The Doctor lives in the house with the brown roof.
- The house with the Renault in the driveway is next to the house next door to where the Doberman lives.
- The murderer?s Poodle went missing on Sunday.
- The Lawyer hates dogs but loves cheesecake.
- The man who drives the Porsche is a keen jogger and was seen running past the victim?s house just after midnight on Wednesday.
- The victim used to enjoy playing lacrosse on Tuesday evenings.

If you solve the mystery all the clues will fit together like a successful crossword puzzle. If you are having difficulty you can email me for some clues.
If you would like to drive all your friends crazy with this you may copy it and send it to them providing nothing is changed and the full contents, including the resource box below remains intact.
Happy problem solving and remember - books are a wonderful source of education.
Hint: Make a drawing of the five houses.
