Embodiment Construction

[0137] In order to further describe the structure of the present invention, the following will be described in detail in conjunction with the accompanying drawings of the embodiments.

[0138] Such as figure 1 As shown, the coreless linear motor 1 is composed of a magnetic track 2 and a coil assembly 3, wherein the magnetic track 2 includes a plurality of permanent magnets 21 placed in front and back in two rows, as shown in figure 2 As shown, to form a row of alternating positive and negative magnetic field regions; as shown in Figure 3 (a) and (b), the coil assembly 3 consists of a plurality of three-phase U, V, W unit coil groups 31 staggered and axially arranged , and then encapsulated through the resin layer 32 .

[0139] As shown in Fig. 4 (a) and (b), the first embodiment of the present invention overlaps two sub-coils 41, 42 with the same width and thickness of Unit coil 4 of T1+T2. Since the individual sub-coils 41 and 42 are relatively thin, they are easy to ben...

Abstract

The invention discloses a unit coil, a coil assembly and an ironless linear motor. The unit coil comprises a plurality of sub-coils which are mutually arranged in parallel and are respectively bent at least once at the non-acting edge in the axial direction; the coil assembly comprises a plurality of three-phase unit coil groups which are arranged along the running direction, wherein each three-phase unit coil group is formed by arranging three same unit coils in a staggered and overlapped mode and then packaging by a resin layer, and each unit coil is formed by arranging a plurality of bent sub-coils in an overlapped mode; and the plurality of bent sub-coils are overlapped for sufficient thickness or arranged for sufficient width to obtain sufficient thrust, and a magnetic track is matched to form an ironless linear motor. In the structure, by utilizing the unit coils formed in a staggered and overlapped arrangement mode, the space requirement of the coil assembly can be effectively reduced, and the sub-coils can be formed and manufactured easily and can not be damaged easily.

Description

technical field [0001] The present invention relates to a unit coil, a coil assembly and an ironless linear motor, in particular to a unit coil comprising a plurality of sub-coils juxtaposed with each other and having at least one bend on the non-active side in the axial direction, and a A winding, arrangement design and wiring method of a coil assembly, and a coreless linear motor including the coil assembly and a magnetic track. Background technique [0002] The existing coreless linear motors have three coil arrangements: non-overlapping concentrated windings, overlapping concentrated windings and printed circuit boards; Figure 9 with Figure 10 It is an arrangement of concentrated windings, which is to arrange a plurality of unit coils 10 together, wherein each unit coil represents a phase U, V, W of the linear motor, and cooperates with the magnetic pole pitch of the permanent magnet 101 to generate propulsion; Figure 9 Shown non-overlapping and Figure 10 The differ...
