It includes a front machine frame, said front machine fram is equipped with a side frame fitting with its edge, the sensor is mounted on the sensor circuit board, and said sensor circuit board is mounted in the side frame of said front machinef rame, said sensor circuit board and the above-mentioned side frame are made into tightly-fitted state, and are fixed by utilizing attached injection-moulded component.
Description
One, technical field:
The present invention relates to a kind of fixed component, specifically, relate in particular to the fixed structure of a kind of switched reluctance machines (SRM) control with transducer and sensor line plate.
Two, background technology:
Its rotor structure of the switched reluctance machines of generally commonly using (SRM) is not to be provided with coil and permanent magnet, and drive circuit is simple, and manufacturing cost is cheap, and the inertia of rotor is little, can turn round expeditiously in the speed of wide range.Therefore, the structure of this motor has many advantages.
Yet,, need obtain the information of relevant rotor position angle in order to control the speed of this switched reluctance machines.Therefore, need the sensing device that detection position information is used.Above-mentioned sensing device is made up of sensor line plate 10 and the transducer 12 that is installed on the sensor line plate 10 as shown in Figure 1.
The sensor wiring board 10 is to be installed on the forebay 20 of SRM front one side, and the structure of this forebay 20 is to form a frame portion 201 at its edge, and its central authorities are provided with a through hole 20a, the common rotating shaft (not shown) of crossing.This sensor line plate 10 is roughly disk construction, is mounted on a side of forebay 20, and 12 of transducers are positioned at rotor (not shown) radius of turn.
According to above-described conventional art, transducer 12 is provided in a side of on the position of the forebay 20 that becomes vertical configuration with the rotor direction of rotation, the positional information of coming detection rotor.
But, if adopt this conventional art, when sensor installation wiring board 10, because its architectural feature (simple flat shape plate) reason.Coincide on the mmi machine frame 20 can be not fine, up and down or about and alignment error appears, move the position of transducer 12, the result, the positional information of detection rotor causes the SRM functional reliability to reduce exactly.
Three, summary of the invention:
The objective of the invention is to, for solving the problem that prior art exists, the fixed structure of a kind of switched Reluctance Motor Control with transducer and sensor line plate is provided, makes the stationary state of transducer and sensor line plate more reliable, to improve the functional reliability of switched reluctance machines.
The objective of the invention is to realize by following technical scheme.
A kind of switched Reluctance Motor Control fixed structure of transducer and sensor line plate, comprise forebay, this forebay is provided with a frame that matches with its edge, and transducer is installed on the sensor line plate, and the sensor line plate then is installed in the frame of this forebay; It is characterized in that describedly being equiped with the sensor line plate of transducer and the frame of forebay is to be fit-state, and fix, make transducer and sensor line plate keep engagement state by the pedestal moulding that is attachment state.
Purpose of the present invention can also further realize by following technical measures.
Aforesaid switched Reluctance Motor Control is with the fixed structure of transducer and sensor line plate, and wherein transducer is to be connected on this sensor line plate by the cover moulding that is attachment state with the sensor line plate.
The aforesaid switched Reluctance Motor Control fixed structure of transducer and sensor line plate, wherein the thickness of cover moulding makes transducer and sensor line plate keep engagement state less than the height of transducer.
The aforesaid switched Reluctance Motor Control fixed structure of transducer and sensor line plate, wherein the sensor line plate is by between sensor line plate and forebay, the pedestal moulding that is attachment state with the sensor line plate is fixed in the frame of forebay, and is fit-state.
The aforesaid switched Reluctance Motor Control fixed structure of transducer and sensor line plate, wherein cover moulding and pedestal moulding are to be made by synthetic resin.
The present invention makes the stationary state of transducer and sensor line plate more reliable, to improve the functional reliability of switched reluctance machines.
Four, description of drawings:
Fig. 1 generally commonly uses the decomposing schematic representation of switched Reluctance Motor Control with transducer and sensor line plate location structure.
Fig. 2 is the fixed structure decomposing schematic representation of preferred embodiment switched Reluctance Motor Control of the present invention with transducer and sensor line plate.
Fig. 3 is a preferred embodiment switched Reluctance Motor Control of the present invention with transducer and sensor line board fixing structure combination section.
Five, embodiment:
At first, the transducer that the control switch reluctance motor of preferred embodiment of the present invention is used and the fixed structure of sensor line plate, as shown in Figure 2, sensor line plate 11 keeps being close to (adhesion) state with the frame 201 of forebay 20, and is placed on the pedestal moulding 30 of reliable its attachment state of maintenance.
Secondly, as shown in Figure 3, transducer 12 equally by with the sensor line plate 11 reliable cover mouldings 32 that keep engagement states, be connected on the sensor wiring board 11.
Above-mentioned various moulding 30,32 is made by synthetic resin etc., and the thickness of cover moulding 32 is equivalent to 2/3 of transducer 12 height approximately, forms the form surperficial consistent with sensor line plate 11.
The width of pedestal moulding 30 and thickness will keep being inserted into the degree in the middle of the frame portion 201 of forebay 20.Especially to keep being the corresponding to form of perfect arc shape with forebay 20.
If make according to the above-described embodiment of the invention, the assembled state of transducer 12 becomes fastening because of being provided with cover moulding 32.Equally, the assembled state of sensor line plate 11 has also become firmly because of being provided with pedestal injection molding machine 30.
Especially said base moulding 30 on architectural feature because and preceding cover 20 match, therefore, not only can reach the assembled state that keeps sensor line plate 11 reliably, and when assembly manipulation, can shift the sensor line plate 11 that pedestal moulding 30 is housed onto forebay 20 li.Owing to can lean on simple operation that sensor line plate 11 is installed in accurately on the position, therefore, improve assembling operation efficient effectively.
If adopt the location structure of switched Reluctance Motor Control with transducer by the present invention, so, the stationary state of transducer and sensor line plate, become more solid and reliable by moulding, therefore, help accurately to measure the positional information of rotor, improved the functional reliability of switched reluctance machines.
