Abstract

The invention provides a design and verification method of a winding coil of a magnetic suspension linear motor which can effectively solve the problem of long design and manufacturing cycle and highcost of the magnetic suspension linear motor caused by the existing design verification method. The method includes obtaining theoretical design values of a primary stator core and the winding coil according to the design speed of a maglev train and the design principle of the linear motor, comparing whether the linear distance b of the thickness a of the oblique portion of the isosceles trianglestructure at the end of the winding coil occupied on the length direction of the stator core is more than the sum of the stator slot width d1 of the stator core and the stator tooth portion width d2;determining whether the projection distance of the oblique portion of the isosceles triangle structure at the end of the winding coil in the width direction of the stator core is out of limit; whetherthe height h is out of limit after the whole isosceles triangle structure at the end of the winding coil is bent upward.

Description

technical field [0001] The invention relates to the technical field of linear motor design, in particular to a design and verification method for a winding coil of a magnetic levitation linear motor. Background technique [0002] The primary installed at the bottom of the magnetic levitation train car is an important part of the magnetic levitation linear motor, which usually mainly includes a stator core 1 and a number of winding coils 2, wherein the bottom of the stator core 1 is provided with an even number of wires along the width direction of the stator core D. Long extended stator slots 3, see figure 1 and figure 2 , the part of the stator core located between the adjacent stator slots 3 forms the stator tooth part 4, the slot width and slot depth of the even numbered stator slots are equal, and the width of each stator tooth part is equal; the stator core 1 during primary installation The notch of the stator slot 3 faces the side of the rail, and the winding coil 2...
