Linear motor is a slotted permanent magnet AC synchronous motor with double-sided design. Their characteristic is excellent force to volume ratio. The attraction between the main component and two secondary components decreases to a value close to zero. The iron core linear motor has two symmetrically opposed secondary components. The very compact design of the mobile primary components reduces mass and volume. Featuring impressive low mobility, optimal power loss, high power, and compact installation space. This creates the advantage of high acceleration and final speed. The attraction is absorbed by the mechanical structure, without the need to load the guide rail. This not only reduces size and service costs, but also extends the service life of the guide rail.
