Linear Motor Working Principle 3D Animation

 A motor called a linear motor is making quite an impact in packaging industries and CNC machines. When someone says “motor,” the image that comes to mind is usually something spinning, right? A linear motor is an electric motor that has had its stator and rotor “unrolled” thus instead of producing a torque (rotation) it produces a linear force along its length.

However, packaging and CNC machines require motors with linear movement. In this video, we are going to learn about the working of these beautiful motors by understanding a crucial concept about linearly travelling magnetic fields.

A typical mode of operation is as a Lorentz-type actuator, in which the applied force is linearly proportional to the current and the magnetic field.Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors.

Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation applications. High-acceleration linear motors are normally rather short, and are designed to accelerate an object to a very high speed, for example see the coilgun./Lesics
