The cross-sectional shape of the body (2) insertion groove (21) is also matched with an inverted y-shape [please refer to the third figure]. In addition, the section at the position of the first bending section Q3) and the seat body described later ( 2) The cross section of the insertion slot (21) can also be matched with an inverted γ-shape [please refer to the fourth figure] or an inverted T-shape [please refer to the fifth figure]. In addition, the first bending segments (13) ) can also be folded toward the opposite inner side to form a second bending section (14), and the cross-sectional shape of the socket (21) insertion groove (21) corresponds to the first bending section of the coil (丨3): and the sectional shape of the second bending section (upper 4) [please refer to the sixth figure], and the coils (]) may be formed by stacking a plurality of sub-coils (17), each sub-coil (17) On the first side (11) of the inactive side The position of the first bending section (13) is bifurcated and dislocated [refer to the seventh figure, the sub-coil (17) includes the first sub-coils (171> and the second sub-coil) (172), the first first sub-coil (171) and the second sub-coil (172) are in a phase-and-phase-like manner; and the two adjacent coils (1) of the S-Xuan are second on the non-active side The side (12) is relatively bent at a position to form a plurality of mutually interleaved third bending segments (15) 'the coil (1) of the coil group (c) and the second side (12) position of the non-active side A plurality of wires (16) are disposed, and the wires (16) extend to the second side (12) of the non-active side of the coil assembly end (18) and are bent to the coil assembly end (18) coil (1) The linear action side (10) is connected to the external slow line (B), so that an external current can flow through the side coil group (C). The coils (1) the third bending section 099101906 Form No. A0101 Page 7 of 23 0992003748-0 201126875 (15) has the function of guiding the wires (w). The body (2) ' is provided with a socket (21), the socket (21) Sectional shape Corresponding to the shape of the section at the position of the first bending section (13) of the coil (1), and for inserting the coils (1), and at least one cooling passage is disposed on the base (2) ( 22), any one of the cooling channels (22) extends axially along the base body (2). A resin encapsulation layer (3) covers the coils (1) and is exposed to the base body (2) The outer part of the groove (21), and just the sealing groove (21) of the seat body (2). When used, please refer to the ninth circle to combine the creation with a magnet track structure (D) However, due to the structure of the coil assembly (A) of the general ironless linear motor, the seat body (2) is mostly made of aluminum alloy, and the aluminum alloy has a very high heat transfer coefficient, and according to the heat transfer formula: Q = -KA (dT/dX), where Q: heat flux; κ: heat transfer coefficient; a: contact area; dT/dX: temperature gradient, so the coil (J) and the seat (2) insertion groove are added (21 The lack of contact area on the inner wall will effectively increase the heat dissipation rate, and the present invention provides the guide table (16) on the second side (12) of the inactive side of the coils (1), and The second side (12) of the inactive side of the coil end (18) coil is wound to the position of the linear action side (1〇) of the coil (1) of the coil assembly end (18), and The portion (23) is connected to the outer mirror wire (B) of the resin encapsulating layer (3), and the wires (16) are not disposed directly from the first side (11) of the inactive side of the coils (1). Thereby, the space of the first side (11) of the inactive side of the coil (j) is vacated, and the first bending section of the non-acting side of the coil (丨) forms a first bending section (13) 099101906 The surface area is increased, the form number A0101 can increase the contact area with the wall of the socket (21) of the base (2) and the wall of 0992003748-0 201126875, which can increase the heat dissipation rate. The second bending segments (14) may be formed by bending the first bending segments (13) toward the opposite sides thereof according to the use requirements, thereby adding the coils (1) and the seat. The contact area of the inner wall of the body (2) insertion groove (21) makes the heat dissipation rate more improved. In addition, the coils (1) may also be composed of a plurality of sub-coils (丄7). Each of the sub-coils is separated from each other at the position of the first bending section (ι3). The cross section has a plurality of sections and shapes, and the contact area with the seat body (2) is further increased, thereby further increasing the heat dissipation rate. Ο The seat body (2) can accelerate the heat convection with the air by the action of the cooling passage (22), lower the temperature of the seat body (2), and keep the seat body (2) plugged. The proper temperature gradient between the inner wall of the groove (21) and the contact area of the coils (1) also has the effect of increasing the heat dissipation rate of the coils (1), and the user can also follow the shape of the seat body (2). The section at the position of the first bending section (13) is in the shape of an inverted square, an inverted gamma, a reversed or a plurality of points, and is added to the body (2). The number of the cooling passages (22) accelerates the heat convection of the surface of the seat (2) and the air to increase the heat dissipation rate. Since the coil group (C) includes a plurality of coils (1), the coils (1) are bent and bent by the wires and thus cannot be formed accurately, when the coil group (C) is coupled to the socket (2) insertion slot ( 21) When the resin encapsulation layer (3) is filled and infiltrated, it is easy to contact with the surface of the socket (2) of the socket body (2), and the insulation capability is only the insulation capability of the insulation layer on the wires of the coils (1); Insulation capability, therefore providing a thin layer of insulation (24) on the surface of the socket (21) of the above-mentioned base (2) [refer to the eighth figure], the material of the insulating layer (24) can be a resin for infusion, Insulating coating, varnish, pus edge tape, electrical insulation paper, etc., can be attached to the body by infusion, plating, coating 099101906 Form No. A0I01 Page 9 / 23 pages 0992003748-0 201126875 2) The surface of the insertion slot (21) is combined with the coil assembly (C) to improve the insulation performance of the coil (1) and the base (2); to maintain a high heat dissipation effect, the insulating thin layer (24) The thickness is less than 1mm.
