Linear motor how does it work

Their thrust is caused through the interaction of magnetic fields within the motors, by magnetic attraction and repulsion. In a synchronous motor the rate of movement of the magnetic field is controlled, usually electronically, to track the motion of the rotor.

Yes , it works with the same principle as any other motor. However on a linear motor, the magnets are placed alligned on a a flat surface, making the element that we want to move i. Does it work with magnetic levitation? No… but almost. Linear motors. What is a linear motor. Ironcore motor principle. No Backlash: A direct drive approach has no backlash such as obtained in leadscrews, gears, belt drives, and pinions.

Very Smooth Operation: Linear packages provide smooth operation due to the elimination of mechanical linkages. Long Life: Indefinite life expectancy under normal operating conditions can be expected due to the simplicity and part reduction.

Unlimited Stroke: Stroke lengths are not limited as with ball screws. It is easy to extend the stroke by simply adding another section. By Alexander Hinds, W2Tech If you're new to automation, this article will help describe the different types and inner workings of linear motors. Did you enjoy this great article?

Linear induction motors power Tomorrowland Transit Authority formerly known as the People Mover , moving large cars at smooth, slow speeds through Tomorrowland. At each of the hills, the linear induction motors launch the tubes through the uphill sections.

This method of propulsion in water coasters is called hydromagnetic technology. Thunder Rapids, to open in , will be the first water coaster is the USA to utilize hydromagnetic technology. Linear induction motors are combined with turbine technology to keep the tube speeding along the slide and over the hills. Cancel Search. Published February 09, What is all the hype about the Hyperloop? Why Use a Linear Induction Motor?

Linear Induction Motor Applications LIMs can be found in theme park rides, water rides, people moving systems, high speed transportation and maglev propulsion applications. Here are some well-known examples: Hyperloop Hyperloop is a high-speed transport system for passengers and goods, incorporating reduced pressure tubes, pressurized pods, linear induction motors, and air compressors.
