Abstract
The utility model discloses a brushless motor. The brushless motor comprises a front end cover and a rear end cover which are arranged in an opposite manner, and a motor shaft which is supported between the front end cover and the rear end cover. A magnet ring is fixed on the motor shaft. A stator is arranged in a manner that the magnet ring is surrounded by the stator. An insulated sideboard is arranged in an inner cavity which is located at one side of the rear end cover. A support which is protruded towards the rear end cover is arranged on the insulated sideboard. A circuit board provided with Hall elements is clamped on the support. According to the utility model, by clamping the insulated sideboard on the support of the insulated sideboard, what a user needs to do is to ensure the accuracy of the position of the support on the insulated sideboard, so the best positions of the Hall elements and the magnet ring on the insulated sideboard can be realized without adjusting the position of the circuit board during installation, so that the best motor working performance can be realized.
Description
Technical field
The utility model relates to a kind of brushless electric machine.
Background technology
In brushless electric machine, arrange in the circuit board Hall element and magnet ring between need adjust to optimum position, can realize the optimization of power of motor.And present wiring board normally is arranged on the motor end plate, in practical operation, be difficult to the position adjustments between Hall element and magnet ring is arrived the best, always exist certain deviation between Hall element and magnet ring, be unfavorable for reaching the service behaviour of motor the best, cause certain energy loss.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of position that need not to regulate between Hall element and magnet ring is provided, realize the brushless electric machine of motor optimum working performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of brushless electric machine, comprise the front end housing and the rear end cap that are oppositely arranged, be supported in the motor shaft between front end housing and rear end cap, be fixed with magnet ring on motor shaft, stator arranges around the magnet ring surrounding, the inner chamber that is positioned at rear end cap one side is provided with the insulation side plate, described insulation side plate is provided with the outstanding support of end cap direction backward, is connected with the wiring board with Hall element on support.
The beneficial effects of the utility model are: the utility model is by on the support that wiring board is connected to the insulation side plate, as long as guarantee the accurate of insulation side plate upper bracket position, so when mounted, just need not the wiring board position is adjusted, just can realize the best of position between Hall element on wiring board and magnet ring, thereby realize the service behaviour of motor the best.
