Advantages of linear motor

(1) has a simple structure. The tubular linear motor directly produces linear motion without intermediate conversion mechanism, which greatly simplifies the structure, reduces the inertia of motion, and greatly improves the dynamic response performance and positioning accuracy. At the same time, it also improves the reliability, saves the cost and makes the manufacture and maintenance easier. Its primary level can directly become a part of the organization, and this unique combination further embodies this advantage.

(2) Suitable for high-speed linear motion. Because there is no constraint of centrifugal force, ordinary materials can reach higher speed. Moreover, if the air cushion or magnetic pad is used to keep the primary and secondary gaps, there will be no mechanical contact during the movement, so there will be no friction and noise in the moving parts. In this way, the transmission parts are not worn, which can greatly reduce the mechanical loss, avoid the noise generated by towing cables, steel cables, gears and pulleys, and improve the overall efficiency.

(3) The utilization rate of primary winding is high. In the tubular linear induction motor, the primary winding is pie-shaped and there is no end winding, so the winding utilization rate is high.

(4) No side effect. Transverse effect refers to the weakening of the magnetic field at the boundary caused by transverse interruption. The cylindrical linear motor has no transverse interruption, so the magnetic field is evenly distributed along the circumference.

(5) It is easy to overcome the problem of unilateral magnetic pull. The radial pull forces cancel each other, and there is basically no problem of unilateral magnetic pull force.

(6) Easy to adjust and control. By adjusting the voltage or frequency, or changing the secondary material, different speeds and electromagnetic thrust can be obtained, which is suitable for low-speed reciprocating operation.

(7) Strong adaptability. The primary iron core of linear motor can be sealed with epoxy resin as a whole, which has good anti-corrosion and moisture-proof performance and is convenient to use in humid, dust and harmful gas environments. It can also be designed into various structural forms to meet the needs of different occasions.

(8) High acceleration. Compared with other lead screws, synchronous belts and rack-and-pinion drives, this is a remarkable advantage of linear motor drive.
