Linear induction motor

The range of applications includes sensor-free induction motors , permanent magnet servo motors in standard torque or linear motor versions, and ultra- dynamic . Linear Induction Motor abbreviated as LIM is a special purpose system that we use to achieve rectilinear motion rather than rotational motion as in the case of conventional motors. The shape and operation of a linear induction motor can be visualized as depicted in the figure by making a radial cut in a rotating induction machine and flattening it out. A linear induction motor provides linear force and motion rather than rotational torque.

The Linear Induction Motor is similar in construction to a circular motor that has been opened out flat.

The magnetic fiel instead of rotating, now sweeps across. A Linear Induction Motor (LIM) is an advanced version of rotary induction motor which gives a linear translational motion instead of the rotational motion. How Does a Linear Induction Motor Work?

Linear induction motor (LIM) theory is most easily understood as a rotary motor that has been cut . This video explains how a linear induction motor works.

As a kind of special motors, linear induction motors (LIM) have been an important research field for researchers. Linear ( induction ) motor definition: an electric motor that produces thrust in a direct line, as distinguished from the rotary. Meaning, pronunciation, translations . The linear induction motor offers considerable advantage at high speeds, it is not limited by centrifugal force and is independent of adhesion.

In this article is investigated the distribution of magnetic field of linear induction motor. The are two models for simulation: three-phase asynchronous linear motor. The performance of linear induction motors is degraded primarily because the finite length of the winding introduces harmful field disturbances originating at the.
