Embodiment 1

[0072] like Figure 4 and Figure 5 As shown, a winding method for a single-phase winding structure of an axial field motor with poles, the number of layers of the PCB board is 2N, including Figure 4 structure with a first layer winding period p-1 as shown, or Figure 5 The structure of p-2 is shown, or a similar p-n structure (n=1, 2, . . . , p-1). The selection of the period number of the first layer winding is determined by the position of the electronic device and the space required by the drive circuit. The two terminal lines of the winding are located on the first layer of the PCB. The winding adopts a centralized structure with a maximum span of 180° electrical angle; the number of winding layers is even; except for the first layer, the windings on each layer are composed of winding periodic rings with the same number of motor poles p; adjacent The winding layers are connected in series through connection holes. Since the number of cycles of the first-layer windin...

[0074] A winding method for a single-phase winding structure of an axial field motor with poles, the number of layers of the PCB board is 2N, including Image 6 The winding structure shown. For a PCB with 2N layers, every two layers constitute a PCB component, forming N components in total. The winding tail of each component is connected to the head of the next component with vias. The tail end of the last component is connected to the first layer of the first component by vias, and is connected to the port of the driver chip. The presence of vias does not affect the layout of the PCB windings. Obviously, this winding arrangement can further increase the number of turns of the winding and simplify the production conditions of the PCB.

Abstract

The invention provides single-phase winding structures used for axial magnetic field motors and a coiling method thereof, a printed circuit board and a motor. The windings are arranged on 2N layers of PCB. The windings arranged on all layers of PCB except for the first layer of PCB are provided with winding cycle rings of which the number is the same with that of motor magnetic poles. The adjacent winding layers are serially connected via connecting holes arranged at the central parts of the winding cycles. The head end and the tail end of the winding end parts are arranged on the first layer of PCB. Cost of the windings is relatively low; the motor coefficient of the windings is relatively high; and the windings are realized through the mode of the PCB so that the shape of the 2D windings can be arbitrary, and the size and the thickness of the windings can be accurately controlled. The aforementioned is important for realization of the thin motor structure and enhancement of motor performance; and the lines of a motor driving circuit, a Hall sensor circuit and other electronic devices can be manufactured on the same PCB forming the motor windings so that utilization rate of motor space can be enhanced.
