Detail
Linear motor is a kind of transmission device that converts electrical energy directly into mechanical energy for linear motion without any intermediate conversion mechanism. Its main advantages are fast response, high acceleration and high linear speed, no friction, easy to control and adjust. Its working principle can be regarded as a rotating motor according to the radial section, and spread into a plane and become, the most commonly used type of linear motor is flat and U-shaped groove type.

MAJOR ADVANTAGE
High stiffness, linear motors are directly connected to the load, so between the motor and the load, there is no transmission gap and practically no flexibility. When the linear motor drives the load in motion, iron cores linear motors show extremely high dynamic stiffness.
The positioning accuracy is high, where linear operation is required, linear motors can facilitate direct transmission, thus eliminating many positioning errors during working. It can also greatly improve the positioning accuracy of the entire system if it is controlled by the microcomputer.
High-speed response, It cancels some lead screws and other mechanical transmission parts which accelerate response time to improve the dynamic response of closed loop control system.
Quiet, low noise. It works quietly because it cancels lead screws and other components
Which brings mechanical friction and uses rolling guides or magnetic suspension guide (no mechanical contact).
Permanent magnets in linear motors are usually modular design, and each module can be extended to any length which it needs. However, it actually can be limited by cables or other factors.
High speed, linear motors can be directly connected to the load to control the position
from high to low speeds. The stator and the rotor, as rigid parts, ensure the quiet operation of the linear motor and the core operating parts of the whole mechanism with high stiffness.
The performance of the linear motor can be made by splicing the stator, and multiple rotors can be configured on the same stator to facilitate multiple independent operation in the same axial direction.
