Motor Technology: What You Need to Know about Linear Ones


In this present time, most of the motor technologies are established to run in a rotating fashion. It might be an issue when the need to generate a straight move arises. In order to get linear output you might be forced to get and maintain extra components like pinion gears, pulleys, belts and so on. As a result of this, you are just wasting precious time and of course money.

Well, to solve such an issue, various engineers and professionals opt to elevate their system to use a linear motor. These types of motors run in a straight line and follow your orders, all with a negligible number of components. Well, have you seen the extraordinary magnetic levitation trains that float on air rather than rolling on wheels? These are entirely electric but rather than using general or ordinary electric motors that spin around, these use a type of unwrapped motor known as a LM that causes them to move at a really high speed in a straight line.

The rotor spins within the stator and the entire motor is fixed in place. A linear one is like a normal electric motor that has been unwrapped and placed in a straight line. The rotor actions past the stator as it turn. Actually these linear ones are electric induction motors that generate motion in a straight line instead of rotational motion. In a conventional electric motor, the rotor spins within the stator but in a linear one, the stator is always unwrapped and it is laid out flat and the rotor moves passes it in a straight line. These motors frequently use superconducting magnets that are cooled to low temperatures to diminish power consumption.

The simple principle behind the concept of linear one was discovered in the year 1895. However practical devices were not developed until the year 1947.During the time of 1950s, British electrical engineer Eric Laithwaite (1921–1997) began to think if linear motors could be used in electric weaving machines.He researched at Imperial College, London and attracted universal recognition in the 1960s following a speech to Royal Institution entitled "Electrical Machines of the Future." It was really a meaningful and decisive speech.

Presently, these motors are used in all types of machines that need linear motion like overhead traveling cranes and even the beltless conveyors for moving sheet metal. These are perhaps best known as the basis of motive power in latest generation of high-speed magnetic levitation trains that promise safe travel at extremely high speeds but are expensive and mismatched with existing railroads. Remember an ordinary or a general electric motor is all about rotation:the coils in the centre, rotor turns within the stator.These linear ones have many advantages as compared to ordinary motors. The most apparent one is that there are no moving parts to get wrong.Since platform rides above track on a cushion of air, there is no harm of energy to friction or vibration.


The bottom line is that these linear ones are getting used extensively both in big and small projects.
