Concrete advantage of the present utility model is as follows:
Adopt two magnet arrays and double-iron core design, the phenomenon of jolting of not moving, repetitive positioning accuracy is good.
Adopt striated pattern chi and decoder to provide signal feedback, guarantee positioning accuracy for rectilinear motion.
Three, description of drawings
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structure chart of traditional iron core formula linear electric motors integral body
Fig. 2 is the structure chart of the utility model double-iron core linear electric motors
Four, embodiment
As shown in Figure 2, the utility model is made up of carrier platform 11, iron core 12 (two), winding coil 19, motion guide rail 13, two-sided magnet array 14, yoke 15, motor base 16, grating chi 17 and grating chi decoder 18.Two-sided magnet array 14 is installed on the yoke 15, and its length can suitably increase or reduce as required.For reducing the speed ripple, the angle excursion that magnet adopts is between 80 ° to 90 °.Iron core 12 is made of some silicon steel plate stackings, and winding coil 19 forms three phase windings in certain sequence and is incorporated into respectively in each iron core 12.Motion guide rail 13 connects motor base 16 and carrier platform 11.Grating chi decoder 18 is with 11 motions of carrier platform.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content in the utility model claim change and modification, all should be technology category of the present utility model.
