Abstract
Disclosed is a motor Hall element fixing device which comprises a stator mounted on a motor shaft, and a Hall element is fixed on the stator. The motor Hall element fixing device is characterized in that a screw hole is arranged on the stator and a fixing hole is arranged on the Hall element; the fixing hole is fixed with the internal threads of a stay stub through bolts; external threads are arranged on the other end of the stay stub; and the external threads are connected with the screw hole of the stator. The motor Hall element fixing device has the following advantages that: firstly, the Hall element is fixed with the stator through the stay stub and is detachably connected with the stator, thus avoiding damages to the Hall element when incasing the Hall element; secondly, the Hall element is not directly connected with the coil of the stator, so the temperature of the coil of the stator can not be transferred to the Hall element, thus preventing the solder joints from falling off, improving the service life of the Hall element and thereby improving the service performance of the motor; thirdly, the Hall element, the stator and the stay stub are all connected through screw threads, so the process is simple and the operation is convenient.
Description
Technical field
The utility model relates to motor Hall element fixture, belongs to machine field.
Background technology
Electric motor car uses flexibly, and applicability is wide, can be on streets and lanes, backroad by bike; Without manpower to pedal, speed is fast, and is laborsaving, save time; Compare the saving energy with motorcycle, pollution-free; Add the profile better appearance, especially be fit to the women and use, so comparatively fast developed in recent years.Motor is the critical component of electric motor car, and the quality of motor directly influences factors such as electric motor car climbing capacity and mileages of continuation.Motor can be divided into brush motor and brushless electric machine, brush motor relies on commutator and brush to finish commutation jointly, noise was big when but this administration of power supply was worked, the life-span of motor, so generally use brushless electric machine now, brushless electric machine relied on controller to finish because the heavy wear of commutator reduces greatly, its controller generally adopts switching Hall components, after utilizing Hall element to carry out electronic commutation, not only make motor rotation very steady, and can be to the direct speed governing of motor.But the Hall element that motor adopted of existing use Hall element is directly to contact with stator coil, coat a certain amount of silica gel on the surface of Hall element, colligation is carried out in the Hall angle bending, there is following shortcoming: first, Hall element directly contacts with stator coil (being stator enamelled wire), because the enamelled wire temperature is higher, cause the components and parts solder joint on the Hall Plate to come off easily, under the situation of long-time climbing or long-time heavy load, even also can cause the components and parts solder joint on the Hall circuit plate to come off at gluing on the circuit board, motor is broken down; The second, when crooked Hall angle, troublesome poeration not only can make Hall angle and enamelled wire collide in the time of also can being subjected to clashing into because of misoperation or stator and cause the stator short circuit, and it is unusual that motor is occurred.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of make Hall element and stator coil indirect contact are provided, thereby guarantee that Hall element prevents that solder joint from coming off under the operating hot environment of motor, make motor rotation normal, and production technology is simple, the motor Hall element fixture of being convenient to operate.
The technical scheme of the utility model motor Hall element fixture is: comprise the stator that is installed on the motor shaft, fixing Hall element on the stator, it is characterized in that being shaped on screwed hole in the described stator, be shaped on fixing hole in the Hall element, fixing hole fixes through the internal thread of screw and supporting studs, the other end of supporting studs is shaped on external screw thread, and external screw thread is connected with the screwed hole of stator.
Motor Hall element fixture of the present utility model, compared with the prior art, have following advantage: the first, Hall element fixes by supporting studs and stator, become and removably connect, in the time of can avoiding occurring pasting the vanning of fastening-type Hall element and the damage that causes; Second, Hall element does not directly contact with stator coil, the temperature transfer that prevents stator coil (being stator enamelled wire) is to Hall element, make the weld point temperature on the Hall element not reach fusing point, avoiding occurring solder joint comes off, improve the life-span of Hall element, thereby improved the serviceability of motor; The 3rd, all adopt thread connecting mode between Hall element, stator and the supporting studs, technology is simple, is convenient to operation.
Motor Hall element fixture of the present utility model has fastening glue-line first between the screwed hole of its described stator and the external screw thread of supporting studs, can strengthen linking intensity, prevents to become flexible.Fastening glue-line second is arranged between the internal thread of its described screw and supporting studs, can prevent screw loosening.
Description of drawings
Fig. 1 is the structural representation of the utility model motor Hall element fixture.
Embodiment
The utility model discloses a kind of motor Hall element fixture, as shown in Figure 1, comprise the stator 2 that is installed on the motor shaft 1, fixing Hall element 3 on the stator 2, it is characterized in that being shaped on screwed hole 21 in the described stator 2, be shaped on fixing hole 31 in the Hall element 3, fixing hole 31 fixes through the internal thread 51 of screw 4 with supporting studs 5, the other end of supporting studs 5 is shaped on external screw thread 52, and external screw thread 52 is connected with the screwed hole 21 of stator.Compared with the prior art, the technical program has following advantage: the first, Hall element 3 fixes by supporting studs 5 and stator 2, promptly between each part for removably connecting, in the time of can avoiding occurring pasting the fastening-type Hall element and case and the damage that causes; Second, Hall element does not directly contact with stator coil, the temperature transfer that prevents stator coil (being stator enamelled wire) is to Hall element, make the weld point temperature on the Hall element not reach fusing point, avoiding occurring solder joint comes off, improve the life-span of Hall element, thereby improved the serviceability of motor; The 3rd, all adopt thread connecting mode between Hall element 3, stator 2 and the supporting studs 5, technology is simple, is convenient to operation.When reality is made, need height to supporting studs 3 through meticulous calculating, make it neither to produce to interfere with electric motor end cap, can not contact again, thereby make the Hall element minimizing of being heated with stator coil; The size and shape of also tackling Hall element carries out the precision design, just can avoid Hall element and electric motor end cap to interfere.Between the screwed hole 21 of its described stator and the external screw thread 52 of supporting studs 5 fastening glue-line first 6 is arranged, can strengthen linking intensity, prevent to become flexible.Between the internal thread 51 of its described screw 4 and supporting studs 5 fastening glue-line second 7 is arranged, can prevent screw loosening.
