Electric Linear Motors

Linear electric motors are a type of linear motor that uses electromagnetic fields to generate linear motion. They are also known as electromagnetic linear motors or simply electric linear motors. Linear electric motors use a similar principle as rotary motors, where a magnetic field is used to create force and motion. However, instead of rotating a shaft, the magnetic field moves along a straight path to generate linear motion. This is achieved by using a series of stationary and moving electromagnets that interact with each other to create a traveling magnetic field.

Electric Linear Motors are similar to a rotating motor that is dissected and unfolded for operation. In a rotating motor, the same electromagnetic effect produces torque, while in a linear motor, the linear motor operates like a rotating motor dissected and spread out. In a rotating motor, the same electromagnetic effect produces torque, while in a linear motor, direct driving force is generated. 

In many applications,Electric Linear Motors have significant advantages over traditional rotary drive systems. For example, a linear motor does not require intermediate mechanical components such as gears, ball screws, or belt drives to connect the motor to the load. The load is directly connected to the linear motor. Therefore, there is no gap or elasticity from the moving parts. Therefore, the power performance of servo control can be improved, and higher levels of accuracy can also be achieved. Electric Linear Motors have a low inertia and low noise driving system due to its lack of mechanical transmission components. Additionally, mechanical wear only occurs in the guidance system. Therefore,Electric Linear Motors have better reliability and lower friction losses than traditional rotary drive systems.

Engineering Design of Electric Linear Motors
The component linear motor is composed of a motor coil and a separate magnetic track.
The coil group is referred to as the “mover” and sometimes also referred to as the primary component. The actuator generally consists of a motor coil, a connecting plate or mounting rod, which allows the coil to be connected to the base plate. The motor cable usually extends from one side of the package.
Magnetic tracks are sometimes referred to as secondary components. Depending on the type of linear motor selected, the magnetic rail can use single row magnets or dual sided magnets that provide balanced attraction.
The ability to independently select linear motor components provides users with an economical solution and provides complete flexibility for integration into the machine. However, this flexibility also requires consideration of motor characteristics, linear feedback technology, cooling methods, performance of servo amplifiers, and control systems.
