Abstract
The invention relates to the technology field of a motor and especially relates to a rapid direct-current brushless motor structure. The structure comprises a shell and a rotating shaft which passes through an internal portion of the shell and is connected to a motor rotor. Two enhanced balanced fixed annular steel sheets which take a center shaft of the rotating shaft as a symmetric shaft and are centrosymmetric are fixed to a surface of the rotating shaft. Each enhanced balanced fixed annular steel sheet is connected to a brake spring which is extended towards a shell direction. The other end of the brake spring is connected to a brake block. A solenoid coil is arranged in the brake block. Operation of the structure is stable, a brake effect is good and a service life is long.

The spacing guiding wall block of the spacing guiding of sidepiece of block.Improve braking effect, it is ensured that stablizing for braking procedure, reduce equipment damage.
Used as to the preferred of the present invention, spacing guiding wall block is provided with and the brake block by the side of the sidepiece of brake block
The pre- rubbing action arc convex of sidepiece phase separation.Improve braking effect, it is ensured that stablizing for braking procedure, reduce equipment damage.
Used as to the preferred of the present invention, the two panels in rotating shaft strengthens the tripping spring that balance stationary annular steel disc is provided with
Quantity is equal and corresponds.The stability of motor operation is improved, while improving braking effect.
As to the preferred of the present invention, strengthen balancing the tripping spring that stationary annular steel disc has more than three with a piece of.
The stability of motor operation is improved, while improving braking effect, cost is controlled.
Strengthen balancing on the position being spaced between stationary annular steel disc as two panels to the preferred of the present invention, is located in rotating shaft
It is provided with auxiliary stabilizing fin.The stability of motor operation is improved, noise and vibration is reduced.
As to the preferred of the present invention, with even number stabilizing fin is aided in.The stability of motor operation is further improved, is subtracted
Few noise and vibration.
Used as to the preferred of the present invention, all of auxiliary stabilizing fin is divided into quantity equal two groups and with the central shaft of rotating shaft
It is centrosymmetric for symmetry axis.The stability of motor operation is further improved, noise and vibration is reduced.
Beneficial effects of the present invention：The good integrity of total, structural strength is high and motor operation is stable, noise and shakes
Dynamic to have larger reduction, braking is in time and braking procedure is stable, damages little to equipment itself, and thermal diffusivity is good, is easy to Long-Time Service.
