Abstract
The utility model relates to a device for fixing a hall element of a motor. The device comprises a retainer, a circuit board, a hall element and a heat-shrinkable tube. The hall element is welded to the circuit board which is fixed on the retainer through screws. A notch is arranged on the inner circle of the retainer and the notch is matched with the hall element which is clamped in the notch of the retainer. The hall element is hooped and fixed from outside by the heat-shrinkable tube, and the retainer is fixed on the rear end cover of the motor through screws. A spindle of the motor is provided with a magnetic steel used for sensing the position of a rotor by the hall element. The magnetic steel extends into the hole of the retainer, enabling the hall element to normally detect the position of the rotor. The motor device for fixing the hall element of the motor has stable structure, can be securely installed, is capable of fixing and protecting the hall element, thereby achieving the purpose of accurate motor-reversing, and can be popularized on a large scale.
Description
Technical field
The utility model relates to a kind of device that is used for the fixedly Hall element position on the motor.
Background technology
In brushless DC motor, motor uses p-m rotor, place the Hall element of requirement in the appropriate location of stator, their output links to each other with the power supply circuits of corresponding stator winding, when rotor through near the Hall element time, voltage of Hall element output that the magnetic field order of p-m rotor has been switched on makes the conducting of stator winding power supply circuits, gives corresponding stator winding power supply, produce the magnetic field identical with rotor field polarity, the repulsion rotor is rotated further.To the next position, the Hall element of last position quits work, and the Hall element conducting of the next position makes next winding energising, produces the repulsion field rotor is rotated further.So the work of motor is kept in circulation.Here, Hall element plays the effect of position transducer, is used for the position of detection rotor magnetic pole, and makes rotor magnetic pole always in the face of repulsion magnetic field, and Hall element plays the commutation effect of stator current again.So Hall element accurately the inductiopn rotor determining positions accurately commutation of motor, influence the power output and the stability of rotation of motor the most at last.The position of this and Hall element is relevant.In actual applications, people fixedly Hall element generally are to insert by pin to be welded on the circuit board, there are not other supports, crooked, lodging that Hall element is easy to, these all can have a negative impact to Hall element inductiopn rotor position, and it is pretty troublesome to change Hall element, thus how better fixedly Hall element be one problem to be solved arranged.
Summary of the invention
For addressing the above problem, the utility model provides a kind of device that is used for the fixedly Hall element position on the motor, this device can firm stable fixing Hall element position.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of device that is used for the fixedly Hall element position on the motor, comprise retainer, circuit board, at least one Hall element, heat-shrinkable T bush, described Hall element is welded on the circuit board, described circuit board is screwed on retainer, have the notch that cooperates with Hall element on the circle in the described retainer, described Hall element snaps in the notch on the circle in the retainer, the Hall element banding is fixed in the outside of described heat-shrinkable T bush circle in the retainer, has screw hole on the described retainer, and described retainer is screwed on the rear end cap of motor.The magnet steel that has Hall element inductiopn rotor position to use on the machine shaft extend in the hole of retainer, makes normally detection rotor position of Hall element.
Described Hall element is three.
In order to regulate the relative position of Hall element and motor stator slot arbitrarily, the screw hole on the described retainer is big waist hole.
The utility model Stability Analysis of Structures is installed firmly, and is fixing and protected Hall element, reached the order ground that motor can accurately commutate, and reduced the frequency of changing Hall element, but the large-scale promotion use.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Among the figure: retainer 1, retainer notch 1-1, retainer screw hole 1-2, circuit board 2, Hall element 3, heat-shrinkable T bush 4, screw 5.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of device that is used for the fixedly Hall element position on the motor comprises retainer 1, circuit board 2, Hall element 3, heat-shrinkable T bush 4; Described Hall element 3 is welded on the circuit board 2, described circuit board 2 usefulness screws 5 are fixed on the retainer 1, have the notch 1-1 that cooperates with Hall element 3 on the interior circle of described retainer 1, described Hall element 3 snaps in notch 1-1, described heat-shrinkable T bush 4 is fixed from the outside with Hall element 3 bandings, retainer 1 is fixed on the rear end cap of motor, and the screw hole 1-2 on the described retainer 1 is big waist hole, thereby can regulate the relative position of Hall element 3 and motor stator slot arbitrarily.
The positional precision of the notch 1-1 of retainer 1 can accurately be guaranteed by mould; Hall element 3 snaps in wherein; then the position of Hall element 3 is also fixed, and has guaranteed relative position and the distribution accuracy of Hall element 3 with inductive magnetic steel, also is to have protected Hall element 3 simultaneously.
The utility model is simple in structure, installs firmly, and is fixing and protected Hall element, and motor can accurately be commutated, and has extensive market prospects.
