Abstract
The utility model discloses a Hall element installation structure for iron cores of motors. A motor is provided with a Hall bath, and Hall elements are installed in the Hall bath of an iron core of the motor. The installation structure is characterized in that the mechanical installation angle interval of the Hall elements is 10.43 degrees. Compared with the prior art, the installation structure disclosed by the utility model has the advantages that: when the inter-phase angle of the Hall elements is adjusted to 10.43 degrees, the problem of phase commutation failures of the Hall elements can be solved better, so that the electronic phase commutation of the motor in the process of running is more smooth, thereby improving the running stability of the motor, avoiding the occurrence of motor jitter when an electric bicycle is ridden, and prolonging the service lives of the Hall elements.
Description
Technical field
The utility model relates to a kind of mounting structure of Hall element, particularly a kind of Hull cell layout angle of electric vehicle motor iron core.
Background technology
Hall element is the core component in the electric machine control system, the useful life that commutation shifts to an earlier date or lags behind and all can reduce Hall element.
At present; The mechanical setting angle of the electric machine iron core Hull cell of electric bicycle (being the alternate angle of Hall element) is generally 10.5 °; Such setting angle is easy to generate the commutation fault (producing in advance or hysteresis) of Hall element, and then causes the motor shake in process is ridden in electric motor car; Influence the operating efficiency of motor, bring potential safety hazard for the riding safety of electric motor car.
The utility model content
The utility model technical problem to be solved is to provide a kind of electronics commutation more steadily and the Hall element mounting structure of the electric machine iron core of the long service life of Hall element to above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Hall element mounting structure of electric machine iron core; Described motor offers Hull cell; Described Hall element is installed in the Hull cell of this electric machine iron core, it is characterized in that: the mechanical setting angle of said Hall element is spaced apart 10.43 degree.
Model according to motor is different with use occasion, and as preferably, the electric phase place between the described Hall element can be 60 degree, also can be 120 degree for the electric phase place between your element.No matter which kind of angle is the electric phase place between the Hall element be, the mechanical stagger angle between the adjacent Hall element guarantees to be 10.43 degree, then can avoid breaking down in the Hall element commutation process, improves the motor reliability of operation.
Compared with prior art; The advantage of the utility model is: during the alternate angle adjustment to 10.43 of Hall element °; Can solve the problem of Hall element commutation fault, make that the electronics commutation of motor when operation is more steady, improved the stability of motor operation; Avoid electric bicycle that motor shake, the useful life of also having improved Hall element simultaneously take place when riding.
Description of drawings
Fig. 1 is the iron core structure of electric motor sketch map (Hall element is not installed) of the utility model embodiment.
Fig. 2 is the local enlarged diagram of electric machine iron core behind the Hall element that is equipped with of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; Offer three Hull cells 11 on the electric machine iron core 1 of present embodiment; Be placed with a Hall element in each Hull cell 11, wherein, the electric phase place between the Hall element can be 60 degree or 120 degree; When electric phase place is 60 when spending, the installation direction of Hall element that is positioned at the centre position is opposite with the installation site of the Hall element that is positioned at both sides;
In order to improve the operational reliability of motor, avoid the commutation fault, the mechanical separation angle between adjacent two Hall elements of present embodiment is set to T, T=10.43 °.After repeatedly experiment and test; The mechanical setting angle of finding adjusted Hall element can be realized the steady commutation of motor better; The fault of having avoided the Hall element commutation to shift to an earlier date or lag behind; Improve the operational reliability and the stability of motor, and prolonged the useful life of Hall element.
