Linear induction motor

This device generates linear movement and force other than the rotating torque. Like permanent magnet linear motors (commonly designated as ironless and iron core types) linear induction motors consist of a primary part (analogous to the stator in a rotary induction motor ) and a secondary part (analogous to the rotor in a rotary version). A linear induction motor is a type of linear motor based on a rotary AC induction motor. The stator is cut axially and spread out flat.

In this type of motor, the stator and rotor are called primary and secondary respectively. A linear motor based on the induction - motor principle consists of a car riding on a track. The track is a developed squirrel-cage winding, and the car, which is 4. The linear induction motors use for traction work.

It works on electromagnetic induction principle. Generally, primary winding makes from copper and secondary winding make from aluminum. Formulas and Equations for Linear and Induction Motors. The following equations and formulas related to linear and induction motors can be used to calculate the basic parameters while analyzing and designing a single phase and three phase induction motor.

Linear induction motors can be manufactured in a wide range of force outputs, speeds, and footprints. Linear Motors - (1companies) Synchronous linear motors are often used where the exact speed of a motor must be maintained. AC induction or traction design - AC induction or traction design motors are a class of motors that derives its name from the fact that current is induced. I would be interested in.

It is a special purpose motor that is used for linear motors. This is interesting development of a conventional induction motor. The definition of a linear induction motor is an electric motor that produces and propels motion in a straight line. An example of linear induction motor is a subway train.

The basic construction of linear induction motor is similar to standard rotating motor that has been unwrapped or unfurled laterally. Linear Induction motor is normally referred as Linear motor. It is also known as alternating current induction motor. Whereas the winding of FIG.

The construction of linear induction motor enables us to control starting force by methods, which cannot be used for rotary asynchronous motor torque control. These Motors are one of the best product in our product line. These products are available in market at most competitive rates.

Acceleration is calculated with the following formula: Force in calculated with the following formula: F = ma F = mag so, F = x 0. It’s important to know that the linear induction motor requires a large air gap to have a more significant magnetizing current. However, at the same time, the power factor and efficiency are lower. A similar innovation is the linear synchronous motor (LSM) by Intamin, originally on Superman….

WHAT ARE LINEAR MOTORS? Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. Applying linear induction motors.

Steps towards practical linear motor propulsion in France. The legs are disposed in at least two layers in the slots and. One type of linear motor, the linear induction motor, can be constructed at low cost because it can use a primary side with coils, and a secondary side made of a conductor that is not magnetize such as aluminum or copper.

Due to the relative motion between the flux and the aluminum conductor, a current will generate in this conductor and interacts with the traveling flux to produce a linear force. Other conventional type of induction motor provide rotational movement.

This is an advanced type of induction motor which give linear movement. In this motor stator call primary and rotor known as secondary.

The circular stator becomes a linear stator, defining a single-sided linear induction motor (SLIM).
