[0032] Example 1:
[0033] like Figure 2 As shown, this embodiment provides an integrated Hall plate for use in a modular stator, comprising: a Hall plate body 1, an annular sidewall 2 surrounding the modular stator; multiple stator connection pads 3 on the annular sidewall 2, the stator connection pads 3 being connected to the stator blocks 4 of the modular stator via first connection lines 5; the multiple stator connection pads 3 forming an A-phase region, a B-phase region, and a C-phase region; a wiring channel within the Hall plate body 1, a second connection line 6 within the wiring channel, the second connection line 6 being connected to the multiple stator connection pads 3 to achieve parallel wiring between the multiple stator connection pads 3; the Hall plate body 1 having A-phase pads, B-phase pads, and C-phase pads, the A-phase pads being connected to a stator connection pad 3 located in the A-phase region, the B-phase pads being connected to a stator connection pad 3 located in the B-phase region, and the C-phase pads being connected to a stator connection pad 3 located in the C-phase region.
[0034] The first connection line 5 is routed outside the Hall plate body 1. The A-phase pad, the B-phase pad and the C-phase pad are arranged adjacent to the stator connection pad 3; the A-phase pad, the B-phase pad and the C-phase pad are connected with the stator connection pad 3 through the third connection line.
[0035] As shown in Figure 2 In order to conveniently display the routing relationship between the second connection line 6 and the stator connection pad 3, the second connection line 6 is shown outside the Hall plate body 1, actually, the second connection line 6 is routed inside the Hall plate body 1 through the routing channel inside the Hall plate body 1.
[0036] The Hall plate body 1 is provided with a Hall sensor, and the Hall plate body 1 is provided with a sensor connection pad connected with the Hall sensor. The Hall sensor is a Hall effect magnetic position and temperature sensor.
[0037] The stator connection pad 3 is welded and connected with the phase line led out from the two sides of the stator block 4. The Hall plate body 1 includes four layers of plates with a thickness of 0.8-2 mm. The Hall plate body 1 is a PCB plate.
[0038] The Hall plate body 1 is provided with an A-phase mark, a B-phase mark and a C-phase mark at the positions of the A-phase pad, the B-phase pad and the C-phase pad respectively. The Hall plate body 1 is provided with a stator number adjacent to the corresponding stator block 4, and is provided with a pad number corresponding to the stator number adjacent to the corresponding stator connection pad 3. The A-phase mark, the B-phase mark and the C-phase mark are arranged to facilitate the connection of the phase line and reduce the probability of connection error. The arrangement of the stator number and the pad number facilitates the accurate connection between the stator and the pad and reduces the probability of connection error.
[0039] The embodiment also provides an electric motor including the integrated Hall plate applied to the block stator.
[0040] In the embodiment, the model of the Hall sensor is MT4601. The main reason for arranging the PCB plate as four layers of plates is that three phase lines need to be routed, the current is relatively large, about 20 A, the routing width in the PCB plate needs to be increased, and the ring of the plate is very narrow, so the number of layers needs to be increased. Normally, the current of the Hall signal is small, and two layers of plates can be used.
[0041] Example 2:
[0042] Those skilled in the art can understand the embodiment as a more specific description of embodiment 1.
[0043] The embodiment provides a PCB plate integrating a Hall, a temperature signal and a motor phase line connection function and applied to a motor block stator assembly.
[0044] Traditional motors use enameled wire to generate the three-phase stator windings inside the motor by paralleling them. Hall effect sensors and temperature signals are transmitted internally via a Hall effect PCB board. The current is very small, and the board consists of two layers. Figure 1 As shown. This embodiment is a PCB board for integrating Hall effect sensors, temperature signals, and motor phase connection functions in a motor module stator assembly. It describes an application where the three-phase motor lines of the module stator are connected in parallel within the Hall effect board PCB to output the motor's three-phase signals. The Hall effect board internally carries the three-phase signals, with a maximum current of 20A. It is a four-layer board, as shown... Figure 2 As shown.
[0045] The application of parallel connection of the three-phase output motor wires inside the Hall effect PCB can reduce manual paralleling costs and the use of enameled wire; save space; optimize the process flow, changing the complex paralleling process to a simple soldering process; and increase circuit stability by paralleling inside the PCB. Furthermore, the structure of this embodiment has broad application prospects and potential in future applications with different numbers of stator modules.
[0046] like Figure 2 As shown, in the 12 stator motors, one phase wire from each of the left and right sides of each stator is soldered to the corresponding pads on the Hall effect board. The 24 phase wires are then connected in parallel within the Hall effect board PCB to create the motor's three-phase wiring. The Hall effect board PCB needs to handle the three-phase wiring, requiring a maximum current of 20A, and is a 4-layer board. Traditionally, the three-phase wiring of a motor is generated by paralleling the three-phase stator windings inside the motor with enameled wire, as shown... Figure 1 As shown, in a 12-stal motor, each stator has one phase wire from each of its left and right sides connected in parallel via enameled wire outside the Hall plate to generate the motor's three-phase lines. The Hall plate PCB carries Hall effect and temperature signals, with very low current, and consists of two layers. This method of connecting the three-phase signals in parallel inside the Hall plate provides a foundation for future designs with different numbers of stator modules, and has broad application prospects.
[0047] This invention provides pads on the Hall plate for connecting the phase wires of the stator block, thereby avoiding the processes of manually winding enameled wire and manually paralleling the wires, greatly saving manpower and resources, and simplifying the manufacturing process.
