Advantages of Linear Motor

Advantages of linear motor

(1) simple structure. Tubular linear motor does not need through an intermediate conversion mechanism and produce linear motion directly, the structure is greatly simplified, reduce the motion inertia, dynamic response performance and positioning accuracy is greatly improved; but also improve the reliability, save the cost, manufacture and maintenance more convenient. Its primary level can be a part of the body directly, this unique combination makes this advantage further reflected.

(2) suitable for high speed linear motion. Because there is no restriction of centrifugal force, the ordinary material can also reach a higher speed. And if the initial and secondary air cushion or magnetic cushion between the storage space, movement without mechanical contact, and thus the movement of the parts without friction and noise. In this way, no wear in transmission parts, mechanical loss is greatly reduced, avoid towed cable, cable, gear and belt pulley is caused by noise, so as to improve the overall efficiency.

(3) the utilization rate of the primary winding is high. In the tubular linear induction motor, the primary winding is cake - like, with no end winding, the winding utilization rate is high.

(4) no transverse edge effect. Lateral effect is that the magnetic field at the boundary is weakened due to the lateral opening, while the cylinder type linear motor is not open, so the magnetic field is distributed evenly along the circumferential direction.

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

(6) easy to adjust and control. By regulating the voltage or frequency, or the replacement of secondary materials, can get a different speed, electromagnetic force, suitable for low speed reciprocating operation occasions.

(7) strong adaptability. Linear motor primary core can with epoxy resin sealed into a whole, with better anti-corrosion, moisture-proof performance, easy moisture, dust and harmful gas environment in use in the; and can be designed into a variety of structural forms, to meet the different needs.

(8) high speed. This is a linear motor drive, compared to other leading screw, synchronous belt and gear rack drive a significant advantage.
