Preferably, the outer surface that each described permanent-magnet pole 56 deviates from described rotor core 54 be positioned at rotor center be the center of circle the face of cylinder on, thus make the outline of the cross section of described permanent-magnet pole 56 roughly rounded.
Further, the inner surface of bipolar shoe 143 connection of each stator tooth 141 is provided with a depression 1433, and two extension 1231 connections of each auxiliary tooth are provided with a depression 1233.The part of inner surface except groove 1233,1433 of the pole shoe 143 of the stator tooth of described stator core 10 and the extension of auxiliary tooth be positioned at rotor center be the center of circle the face of cylinder on, like this, form basic uniform air gap between stator and rotor, namely except respective slot 1433,1233, part except compartment between opening 18 and adjacent pole is even air gap.
In the present embodiment, described depression 1433 to 1233 setting can depart from corresponding stator pole axis (center line of stator tooth) L1 certain angle to make rotor pole axis (center line of permanent-magnet pole) L2 of rotor when initial position, the angle Q between described rotor pole axis and stator pole axis is called and starts angle.Preferably, described depression 1433 and 1233 distinguishes the center just to stator tooth and auxiliary tooth, equals or close 90 degree of electrical degrees, thus make rotor can realize twocouese startup with comparalive ease to make starting angle.By changing the electrical current direction of described winding 30, the startup direction of rotor can be changed.
Understandably, according to design needs, the position of described depression 1433,1233 can adjust.As described in depression 1433,1233 depart from toward the clockwise direction simultaneously stator tooth and auxiliary tooth center or while counterclockwise depart from the center of stator tooth and auxiliary tooth, thus make rotor towards the startup in a direction than easy towards another rightabout startup.
In the present embodiment, the quantity of described permanent magnet 56 is four, four described permanent magnets 56 are fixedly installed on the periphery wall of described rotor core 54, and be intervally installed along the circumference of described rotor core 54, each permanent magnet 56 forms a permanent-magnet pole, and the polarity of adjacent permanent magnetic poles 56 is contrary.Described winding 30 comprises two coils, and two described coils are set around on two described stator tooths 14 respectively, and each described coil is through after corresponding accepting groove 15, and winding is on the winding section 141 of corresponding described stator tooth 14.When have in described winding 30 electric current by time, the winding of energising will produce induced field.The magnetic line of force that each hot-wire coil produces is entered rotor by pole shoe, is assisted the extension of the contiguous pole shoe of teeth and stator yoke 12 to get back to stator tooth thus form flux circuit again from rotor via two, namely, the magnetic line of force that each described hot-wire coil produces, respectively via after described winding section 141, bipolar shoe 143, air gap, rotor, two extensions 1231 contiguous with described bipolar shoe 143 and stator yoke 12 between pole shoe 143 and rotor, forms two closed flux circuits.Therefore, in present embodiment, two described coils after powered up, four flux circuits can be formed, also namely quadrupole motor is formed, compared to traditional bipolar machine (interpole do not established by stator), the utility model shortens magnetic circuit, reduces magnetic resistance, thus can promote the power output of described driven unit 100.
Understandably, the formation of four described permanent-magnet pole 56 outer surfaces can be not limited to isocentric circular arc curved-surface structure as described above, such as, the formation of four described permanent-magnet pole 56 outer surfaces can be non-concentric arc surface, as the outer surface of each permanent-magnet pole 56 to reduce to the distance of rotor center along periphery of rotor gradually from the center of outer surface toward two ends and symmetrical about outer surface center line, thus the non-homogeneous air gap about outer surface center line almost symmetry between each permanent-magnet pole outer surface and stator, can be formed.
Preferably, described driven unit 100 is single-phase permanent brushless motor.Thus, above-mentioned driven unit 100 is four pole single-phase permanent brushless motors.Because described single-phase permanent brushless motor only comprises two stator tooths be oppositely arranged 14, two described coils are arranged on two described stator tooths 14 respectively, distance one timing between two described the first side walls 121 of described stator yoke 12, the distance between two described second sidewalls 123 can be made relatively little, thus while the overall dimensions relatively reducing described brushless single phase motor, alleviate the overall weight of described driving mechanism 1, and the power output of described brushless single phase motor is relatively large.Meanwhile, when described brushless single phase motor is arranged in described casing 21, eliminates the outside iron-clad of conventional motors, further reduce it and take up room, make the overall volume of described driving mechanism 1 relatively little.And, the motor of the utility model embodiment, profile is roughly rectangle/kidney-shaped structure, the width (i.e. the size of one group of opposite side) of this structure is less than its length (i.e. the size of another group opposite side), the form fit of motor profile and described casing 21 host cavity 2111, the driving mechanism of design like this, described casing 21 has flat structure (size in motor vertical second sidewall 123 direction is significantly less than the size in parallel electrical machinery second sidewall 123 direction), is particularly useful for having the application scenario in flat space as window regulator.The motor of the utility model execution mode, the ratio of the width (distances between two second sidewall 123 outer surfaces) of rotor maximum outside diameter (i.e. the maximum outside diameter at corresponding permanent magnet place) and stator core can reach more than 0.6, also namely rotor can do large as far as possible, thus the power output of lifting motor.
Be understandable that, the quantity of described permanent-magnet pole 56 is not limited to four, and it can be six, eight, ten, even more.Similarly, the quantity of described stator tooth 14 is also not limited to two, and it can be four, six, eight, ten, even more, only needs to make the quantity of described permanent-magnet pole 56 to be twices of the quantity of described stator tooth 14.Correspondingly, the quantity of described auxiliary tooth is not limited to two as described above, and its quantity can be four, six, eight, ten, even more, only needs to make the quantity of described auxiliary tooth equal the quantity of described stator tooth 14; The quantity of described coil equals the quantity of described stator tooth 14.
In brief, described stator tooth, described auxiliary tooth, described coil and permanent-magnet pole 56, quantitative relation meet following relation: the quantity of described stator tooth 14, described auxiliary tooth and described coil is n, n described stator tooth 14 and n described auxiliary tooth are along the circumferential alternate intervals spread configuration of described stator yoke 12, and each described coil is set around on a described stator tooth 14; The quantity of described permanent-magnet pole 56 is 2n.After above-mentioned n described coil electricity, the identical main pole of n polarity can be formed respectively in n described stator tooth place, form n and the opposite polarity auxiliary magnetic pole of main pole respectively in n described auxiliary tooth place.Wherein, n be greater than 1 positive integer.Above-mentioned motor, flux circuit can be formed between main pole and the auxiliary magnetic pole that is adjacent after the energising of its winding, compared to traditional bipolar machine, magnetic circuit improves, when obtaining identical power output, described motor can reduce the material consumption of winding and stator core, thus can relatively reduce costs; In addition, when external diameter one timing of rotor, the size of described stator core can arrange relatively less, reduces the overall volume of described motor, makes the overall volume of described driving mechanism relatively little.
