Summary:

Today, linear motion in numerous systems is realized by means of a mechanism set

up by a conventional (rotary) electric motor providing circular motion and a belt system or

gear system activated by the motor. All these subsystems are necessary to convert rotary

motion to linear motion. Because of these additions, some problems occur such as frictions

losses, increment in moment of inertia and mass of total system. But fewer moving parts,

reducing losses and longer system life with less maintenance are features expected in such

systems.

To meet these requirements, a tubular constructed linear induction motor design has been

proposed to use instead of rotary motor with other additional systems and then realized.

In the first chapter, some information is given about structures, types and applications

of linear motors and actuators, performance criterions and desing tips. The circutry of the

motor control and six-step inverter are mentioned as well

In second chapter, the realization of the Tubular Structured Linear Asynchronous

Motor design as a mechanic oscillator and the control circuitry are explained.

In the third chapter, some experimental results are obtained to make suggestions

about how to increase efficiecy of the motor and control system.
