Iron core 11 and winding 12 form；The top of iron core 11 is configured to surround the ultra-Left pole 111 in left and right two and right pole 112 of rotor 10；Winding
12 by penetrating the yoke portion left arm of iron core 11, each 1 coil serial or parallel connection of right arm forms；
Rotor 10 is p-m rotor, and radial symmetric sine wave magnetizes as the pole of N, S bis-, the left pole 111 and the right side of insertion iron core 11
Between pole 112, and it is supported in bearing rotary.
The explanation figure of conducting switch drive motor is closed below in conjunction with Fig. 4 motor circuits controllable silicon；To the worked of motor
The following several working condition introductions of journey point：
1st, when rotor is in totally stationary state (cold dead halt state), see Fig. 4 (a) (b) due at this moment fixed
Son does not produce magnetic field, and the N poles of rotor and S poles are also symmetrical distribution, stator silicon steel plate remove about start magnetic hysteresis
Outside, other structures are also symmetrical, thus p-m rotor magnetic field is to the left and right both sides silicon steel sheet of stator for breach (also referred to as starting breach)
Magnetic field force it is equal, but direction slightly offsets from magnetic hysteresis breach, i.e., deflects a low-angle to the direction of first magnetic hysteresis breach, therefore inactive state
When, the N poles of rotor field and S poles keep close to horizontal direction and small to the direction deflection one without magnetic hysteresis breach as axle center using rotating shaft
Angle, but the polarity of the magnetic field of N poles and S poles to the left still to the right is not known.
2nd, when rotor field, polarity detection circuit detects N poles signal, and AC power polarity detection circuit detects electricity
Source minus polarity signal：When see in Fig. 4 (c) circuits export trigger current triggering controlled silicon conducting, machine winding be powered produce stator
Raw left side S poles, the magnetic field of the right N poles, simultaneously because hysteresis and weak is established in the magnetic field that there is magnetic hysteresis indentation, there top on the right of stator
In lower section without magnetic hysteresis indentation, there, at this moment the N poles on the right of rotor and the N poles same sex on the right of stator are mutually exclusive, and make on the right of rotor
N poles from the overdrive condition after static position or normal work toward the right above have the direction (counter clockwise direction) of magnetic hysteresis breach
Certain angle is rotated, at this moment, because the S extremely opposite sex of the N poles on the right of rotor and the stator left side is attracted each other, the N poles on the right of rotor
Go to the left side in the counterclockwise direction again rapidly, and rotor, in the presence of inertia force is moved, it is inclined that N poles continue to left side static position

Raw left side N poles, the magnetic field of the right S poles, simultaneously because hysteresis and weak is established in the magnetic field that there is magnetic hysteresis indentation, there top on the right of stator
In lower section without magnetic hysteresis indentation, there, at this moment because the S poles on the right of rotor and the S poles same polarity on the right of stator are mutually exclusive, and make to turn
The S poles on sub- the right from the overdrive condition after static position or normal work toward the right above have direction (inverse time of magnetic hysteresis breach
Pin direction) rotate certain angle.At this moment, because the N poles heteropolarity of the S poles on the right of rotor and the stator left side is attracted each other, rotor
The S on the right extremely goes to the left side in the counterclockwise direction again rapidly, and rotor, in the presence of inertia force is moved, N poles continue to the left side
Behind the position of any of static position partial below, because between stator and rotor the direction of magnetic field force with just now on the contrary, at this moment rotor whether
Continue to be rotated in the clockwise direction depending on which is big for water sports coherence power in magnetic field force and rotor, impeller and pump house.
Therefore, if p-m rotor magnetic field point to Hall element at be S poles, to machine winding for positive polarity electric current when, stator field
The direction that p-m rotor rotates is driven as in the counterclockwise direction.
4th, when rotor field, polarity detection circuit detects N poles signal, and AC power polarity detection circuit detects electricity
During the positive signal of source：See that Fig. 4 (e) circuits do not export the closing of trigger current controllable silicon, process circuit waits rotor field polarity
Dealt with again after the change of signal or electric power polarity signal.
5th, when rotor field, polarity detection circuit detects S poles signal, and AC power polarity detection circuit detects electricity
During the minus polarity signal of source：See that Fig. 4 (f) circuits do not export the closing of trigger current controllable silicon, process circuit waits rotor field polarity
Dealt with again after the change of signal or electric power polarity signal.
Following results are can obtain from above circuit：
By the forward position for the power supply half cycle for forbidding under current rotor polarity of the magnetic field position may partly causing motor reversal
Or whole driving of the half cycle to motor stator winding, i.e., only allow the magnetic that can make polarity of the magnetic field caused by motor stator and current rotor
The rear part that active force between the polarity of field meets half cycle or half cycle that setting turns to requirement is driven to motor stator winding.
Foregoing circuit has been achieved with following function：At the N poles in p-m rotor magnetic field or S poles sensing Hall element, if
Motor stator winding passes through forward current or reverse current (that is, the positive half cycle or negative half period of power supply turn on), motor stator
When caused stator field makes the Impact direction of p-m rotor identical with the rotate counterclockwise direction set, then trigger；If direction
On the contrary, then rotor field is waited to turn to the rotate counterclockwise direction phase that can be produced Impact direction and set in the power supply half cycle
Just trigger again or the power supply half cycle does not trigger simultaneously, thus, the orientation of circuit realiration motor starts and the function of operation.
Secondly, introduce in embodiment, using further transformation of the above-mentioned electric machine structure to submersible pump structure and its
The course of work of cooperation.
Referring to Fig. 1 and Fig. 2, the water pump of present embodiment, the leaf production of its impeller 9 is into spiral involute, impeller
