For single-phase brushless direct-current motor, stator salient poles logarithm must be equal with the number of magnetic pole pairs of rotor permanent magnet, otherwise
It cannot operate, if four salient poles are arranged on stator, rotor permanent magnet must be filled into the poles 2P=4 (P numbers of pole-pairs).Brushless single phase
There are dead unit problems when dc motor is started and run.Due to the presence of salient pole reluctance torque, rotor magnetic pole center line will be by
It is located in the position of α m=0 or α m=n π electrical angles (n=1,2,3), i.e. 4 positions of mechanical angle 0, pi/2, π, π 3/2, electricity
Motivation will can not be started because of no electromagnetic torque.Dead point is started in order to eliminate, 1 salient pole of stator uses non-uniform gap structure, production

The circular arc in the center of circle forms, it is ensured that the reliable starting of motor.
Hall sensor 21 detects position of the magnetic pole with respect to armature winding of rotor 3, and sending out position in determining position passes
Feel differential signal, after differential signal feeding main control chip LA6585M is amplified processing, corresponding power switch can be controlled
The turn-on sequence of device.When rotor 3 rotates, Hall sensor 21 leads to the difference of the 3 polar susceptibility of magnetic pole N, S of rotor
The differential signal of Hall sensor 21 (H+, H-) output is different, such as Fig. 6.When the extreme faces rotor N are in linear hall element mark
When face, H+, H- amplitude difference are that just, armature winding forward direction is powered, on the contrary then reversed energization, the forward and reverse each energization of armature winding
180 ° of electrical angles, recycle successively, form continuous electromagnetic torque.Drive control device circuit theory is shown in Fig. 5.
When wind turbine stall, the difference of H+, H- output of Hall sensor 21 is zero, and chip interior receives Hall difference at this time
The amplifier output voltage of input is zero, causes the device for power switching of chip interior " H " bridge to end, machine winding " no current "
Pass through, is generated at this time without electromagnetic torque, wind turbine stalling.
Although wind turbine stalls at this time, internal power switching device also ends, and Hall sensor 21 still has output, this
Voltage signal is reached chip interior resistance by Shi Huoer H+ outputs by digit chip LA6585M pins IN+, finally flows through motor
Winding simultaneously forms current path, therefore wind turbine still has electric current to flow through armature winding in stall, causes wind turbine that can attempt to open

The dead point the problem of, meanwhile, linear hall element is set on the printed circuit board of unidirectional fan, for incuding outer rotor magnet steel
End face leakage field receives linear Hall position difference to accurately obtain fan rotor position signal, using single-chip digital integrated circuit
Signal, by differential signal feeding main control chip be amplified processing after, driving internal power circuit work, to ensure wind turbine around
The reliable commutation of group has the function of efficient, low in energy consumption, low noise, built-in locking, restarts automatically, for wind turbine miniaturization
Realization provides good hardware guarantee.
