Abstract

The present invention relates to a device whose stator part has high-performance flat coil. Under the operation condition requiring high current, the occupancy rate of stator coil in the stator wire slot is increased, and it provides a more accurate number of coil turns. The power voltage and operational speed corresponding to the accurate number of coil turns make it precise for the torque constant KT or the back emf KE of motor or generator to be controlled, and further make the design of maximum rated operational speed or back emf voltage for a motor or generator with a fixed volume more accurate. Since the coil can be installed with high occupancy rate for flat coil, the copper wire impedance of flat coil can be lowered. Thus, the motor or generator using the flat coil device of the present invention has a higher operational efficiency, and the maximum rated operational speed or back emf voltage can be easily designed to be more accurate.

Description of the invention () [Fields covered by the present invention] The fields covered by the present invention are the coils of the stator part of the traditional inner rotor, outer rotor motor or generator The winding method can be used to separate the coils, wire sockets, stator ring parts, and stator teeth of the motor or generator through the technical means of the "stator / device with high-efficiency flat coil" of the present invention. As for the city flat line, the unwinding line only uses a single layer-person and it is formed on the coil forming machine in advance. Because it is a single layer press-folding, it can adjust the thickness of the flat wire and accurately control the number of turns of the coil. The generator can flexibly adjust the number of outgoing lines according to the needs of the operating point of operation, and get-the accurate value of the back-EMF constant Ke or the torque constant κτ value, that is to say-very accurate back-EMF voltage or speed operation, The following formula is the relationship between the coil resistance, power supply voltage, and operating speed:

The content of the case is defined as a metal sheet The coils (foil wire wound coils 15) are not used in high current working environments. The coils (15) are mainly rolled by a drum winding machine and are sleeved on the stator coil poles (stator poles 13). The metal sheet also has a corresponding face, a corresponding edge, a wire end (15b), and a wire end (15a); however, the face is sleeved on the surface of the stator coil posts (statorpoles 13), and One of the two sides is set on the bottom side (flat 13a). If so, the end of the wire is embedded inside the metal foil after being wound into a coil (as shown in Figure 2 of the patent (US5866965)). Therefore, the secondary end of the lead wire end (15b) (as shown in the first picture of the patent case) is bound to be processed. The [wire head end] of the sheet metal coil (15) must be led by three folding turns. The process is based on this The first end of the application can be shown in the first picture A to the first picture G. (15b) And the end of the line (15a) leads to the lack of processing that is not easy and wastes processing costs. The first picture can be compared to the coil (15) in the first picture of the (US5866965) patent case. In addition, if If the motor of this patent is to be used in high current applications, it means that the coil must have a large cross-sectional area, that is, a thicker flat wire must be used with a thicker edge. The folding and turning method is bound to be quite difficult in terms of manufacturing engineering technology, because the wire ends of thicker and harder metal foils cannot be easily led to the outside through multiple folding methods (as shown in the first picture A to the first picture D) Therefore, this patent case does not have the wire head end (312) and wire tail end (313) of the present invention which are directly exposed and are finer than high current occasions; --- 1111 ------ I --- order · -------- (Please read the notes on the back before filling in this page)

V. Description of the invention (); ==== Saki efficiency motor [Purpose of the present invention] Workers of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by workers' cooperatives, know that the stator part of the motor or generator is used because it requires high current II. The thicker diameter coils have multiple diameters in the slot (as shown in Figures A to 3_). Among them, although the-line is used, but the diameter of the circle is different from each other. The occupation ratio of the factory slot is also different. At the same time, it is not possible to uniformly occupy the same slot in the same slot. (Shown in G); the reasons mentioned above make the speed design of the motor or generator in the working range extremely difficult, because the following formula: E = Ω · D · β · L · · N / 2 = · Ω · κε 'where the back electromotive force constant KE value is inversely proportional to the armature rotation speed Ω, and the back electromotive force constant κε value is directly proportional to the armature outer diameter D, the air gap magnetic flux density B, the stacked thickness L, and the total number of conductors N, Therefore, when motors or generators of the same size are used in different designs When operating the operating range, the change in the number of turns N of the coil will be inversely proportional to the value of the back electromotive force κE. Based on the above reasons, the thickness of the flat wire rod of the device with a high-efficiency flat coil in the stator section is changed by the present invention. It is [the total thickness of the coil end (216)] + (divided by) [the number of turns required for the flat wire 圏 (31) equal to) of the flat coil side through the vertical post end (211) of the wire slot seat (21) (315) thickness value (as shown in Figure *. · Figures A through C), so you can flexibly design 7 of various turns -------- 1T ------- -^ 9.
