The intuitive feature of the linear motor is that it directly produces linear motion. By directly driving the load, it can achieve high-precision position positioning control from high speed to low speed. There is no direct contact between the actuator(primary) and the stator(secondary) of the linear motor. Both the stator and the actuator are rigid parts, so as to ensure the soundness of the linear motor movement and the high rigidity of the core moving parts of the overall mechanism. Main features: compact structure, small power loss, high speed of fast shift, high acceleration, high speed.
Compared with traditional Motors(rotary Motors, rolling bars), its advantages are more prominent, mainly reflected in the following aspects:
First, it is simple in structure and small in size. It is driven in a straight line by a minimum number of components, and it is only a single moving component. There is no mechanical contact, and transmission power is generated in the air gap. There is no friction other than the linear motor guide rail;
Second, the arbitrariness is strong, and the running stroke is theoretically not subject to any restrictions, and its performance will not be affected by the change in the size of the stroke, and the unrestricted stroke can be achieved by splicing the stator. At the same time, it is also possible to implement multiple independent motion control in the same axis by deploying multiple movers on the same stator;
Thirdly, the precision is high, and the mechanism driven by the linear motor can achieve ultra-precision motion control by enhancing the rigidity and accuracy of the mechanism and feedback elements, and auxiliary temperature control. The coverage includes from a few microns to a few meters per second.
Fourth, the speed of reaction, high sensitivity, and the ability to move smoothly, this is because there is no other mechanical connection or conversion device except for the linear guide rail or air bearing that plays a supporting role. Especially at high speed is a prominent advantage, with a large acceleration of up to 300G;
Five, simple maintenance, long life, work safety and reliability. Due to the small number of components, no contact transmission force is achieved, and the mechanical friction loss is almost zero. Therefore, there are fewer faults and no maintenance. Therefore, the work is safe and reliable, the life is long, and the movement noise is low.
