Coil 30, be set to two and two coils 30 are superimposed is set in rotor 20 circumferential lateral surface from top to bottom, the medial surface of each coil 30 is all installed with the multiple poles pawl arranged in class isosceles triangle, two coils 30 drive rotor 20 to rotate with extraneous power supply UNICOM respectively.
In synchronous machine, the shape and structure and size etc. of the magnetic pole of stationary part can produce certain impact to the normal work of motor, the magnetic pole of rectangular-shaped setting that what existing permagnetic synchronous motor adopted is, rectangular-shaped magnetic pole moment of torsion is relatively little, electric motor starting is bad, and the moment deviation produced when motor positive and inverse is large, machine operation stroke is inconsistent, affects machine operation and normally carries out.
In addition, such structure often causes the problem that vibration is large when machine operation, also may cause motor reversal, cause machine operation mistake, even damage motor when motor load.
For this reason, the present invention devises a kind of high power claw pole permanent magnet synchronous motor, magnetic pole is modified to the pole pawl that class isosceles triangle is arranged, by changing the shape and structure of magnetic pole, increasing moment of torsion, being convenient to the starting of motor, reduce vibration, also avoid the phenomenon that reversion occurs when motor load simultaneously.
Rotate because non-directional easily occurs a coil 30, cause motor reversal easily, therefore, be provided with two coils 30 in the present invention, such being provided with is beneficial to increase starting torque, ensures that rotor 20 keeps directional rotating without under External Force Acting in rotation process.
As shown in Figures 2 and 3, preferably, pole pawl comprises the multiple first pole pawl 31 arranged straight down and the multiple second pole pawls 32 arranged straight up, and the first pole pawl 31, second pole pawl 32 interval is arranged, and each pole pawl is uniformly distributed along the medial surface of corresponding coil 30.
Pole pawl is divided into the first pole pawl 31, second pole pawl 32, is convenient to the generation in magnetic field, the first pole pawl 31, second pole pawl 32 is arranged in back span, and each pole pawl is uniformly distributed along the medial surface of corresponding coil 30, guarantees that Distribution of Magnetic Field is even, is conducive to rotor 20 and rotates.
Preferably, each pole pawl includes head, afterbody and the width of pole pawl increase to afterbody gradually by head.Because pole pawl is that class isosceles triangle is arranged, therefore, the part at the corresponding isosceles triangle drift angle place of head of pole pawl, the part at the corresponding place, isosceles triangle base of afterbody of pole pawl.
Further preferably, the first adjacent pole pawl 31, second pole pawl 32 is in setting of staggering in opposite directions, and the afterbody of the first pole pawl 31 is arranged near the upper surface of corresponding coil 30, and the afterbody of the second pole pawl 32 is arranged near the lower surface of corresponding coil 30.
It is worth mentioning that, sheet metal is installed with respectively in the upper surface of coil 30, lower surface, each sheet metal is provided with equally distributed multiple projection, wherein, each projection bends towards coil 30 medial surface and fits tightly each pole pawl forming above-mentioned correspondence on the medial surface of coil 30, and so the afterbody of each pole pawl is all connected with corresponding sheet metal.
In the present embodiment, the sheet metal being positioned at coil 30 upper surface is the first sheet metal, and each first pole pawl 31 and the first sheet metal are connected as a single entity; The sheet metal being positioned at coil 30 lower surface is the second sheet metal, and each second pole pawl 32 and the second sheet metal are connected as a single entity.Therefore, the afterbody of the first pole pawl 31 is arranged near the upper surface of corresponding coil 30, and the afterbody of the second pole pawl 32 is arranged near the lower surface of corresponding coil 30, and the first adjacent pole pawl 31, second pole pawl 32 is in setting of staggering in opposite directions, is conducive to the distribution in magnetic field.
After the extraneous power supply of connection, coil 30 surrounding produces magnetic field, the N pole (or S pole) in the first sheet metal, the second corresponding magnetic field of sheet metal difference, S pole (or N pole).
Correspond, the first pole pawl 31, second pole pawl 32, after extraneous power supply connected by coil 30, demonstrates the polarity consistent with corresponding sheet metal.Now on the medial surface of coil 30, N pole and S interpolar every arranging and being uniformly distributed, be provided with like this be beneficial to magnetic field be uniformly distributed, rotor 20 stability of rotation in magnetic field.
Preferably, gap is left and the wide setting in adjacent gap between the first adjacent pole pawl 31, second pole pawl 32.Such vibrational power flow is embodied as, and each pole pawl is equidistantly distributed on the medial surface of corresponding coil 30, further defines the position distribution of pole pawl, and so, the Distribution of Magnetic Field that coil 30 produces is more even, is more beneficial to the rotation of rotor 20.

Wherein electric capacity is as voltage-phase mobile in running, helps electric motor starting, after electric motor starting, makes motor enter rapidly steadily strong running status.
The course of work of motor is as follows:
When OV1 connects 220V alternating current, the coil two in two coils 30 produces the advanced pulse signal of phase place, and magnetic field forward (CW) is rotated, and rotor driven 20 rotates forward; When OV2 connects 220V alternating current, the coil one in two coils 30 produces the pulse signal of delayed phase, and FR (CCW) is rotated, and rotor driven 20 reverses.
In conventional motor, coil 30 produces the wavy magnetic field of rectangle after being powered up, and motor oscillating is comparatively large, and the pole pawl in the present invention can make generated magnetic field close to sinusoidal wave shape, and machine operation can be impelled to stablize.
In addition, on two coils 30, the position of the corresponding pole pawl arranged is in setting of staggering in the same way, and the magnetic field that two coils 30 are produced has certain phase difference, ensures that motor more successfully can enter rotating.
This high power claw pole permanent magnet synchronous motor is in an initial condition, reasonable in design, easy to operate; The setting of pole pawl and the concrete distribution situation of pole pawl make electric motor starting good, and orientation accurately, is not easily reversed; Reduce vibration, machine operation is stablized simultaneously; In addition, rotating moment deviation is little, good working effect.
