The magnetizer 100 magnetized for rotor permanent magnet ring of embodiment is according to a first aspect of the present invention described below with reference to Fig. 1-Fig. 6.
The magnetizer 100 magnetized for rotor permanent magnet ring of embodiment according to a first aspect of the present invention, comprising: multiple assembly that magnetizes.
Particularly, multiple assemblies spaced apart that magnetizes is arranged, and multiple assembly surrounding rotor magnet ring 1 that magnetizes.Wherein, magnet ring is configured to the cylinder that cross section is annular, and multiple assemblies that magnetize are looped around the periphery of rotor permanent magnet ring 1, and are evenly spaced apart each other in the circumference of rotor permanent magnet ring 1.
Wherein each assembly that magnetizes includes magnetic conductive part 101 and wire 102, multiple magnetic conductive part 101 along rotor permanent magnet ring 1 circumference distribution and can be one-body molded, wherein each magnetic conductive part 101 all extends along the radial direction of rotor permanent magnet ring 1, the ground winding of wire 102 multilayer multiturn is on corresponding magnetic conductive part 101, wherein multi-layer conductor leads arranges one by one in the radial direction of rotor permanent magnet ring 1, every layer conductor comprise around magnetic conductive part circumferential disc around multiturn wire.
As shown in Figure 1, along rotor permanent magnet ring 1 radial direction from inside to outside, the number of turn of every layer conductor can increase gradually, when each magnetic conductive part is everywhere equal along the radial direction of rotor permanent magnet ring 1, width in the circumference of rotor permanent magnet ring 1, the projection of assembly on the datum plane perpendicular to rotor permanent magnet ring 1 central axis of magnetizing can be formed as substantially, from inside to outside width increase gradually trapezoidal.
As shown in Figure 2, along rotor permanent magnet ring 1 radial direction from inside to outside, the number of turn of every layer conductor can reduce gradually, when each magnetic conductive part is everywhere equal along the radial direction of rotor permanent magnet ring 1, width in the circumference of rotor permanent magnet ring 1, the projection of assembly on the datum plane perpendicular to rotor permanent magnet ring 1 central axis of magnetizing can be formed as substantially, from inside to outside width reduce gradually trapezoidal.
Wherein, the structure of multiple assemblies that magnetize forming magnetizer 100 is identical, that is, from inside to outside, each magnetize assembly otherwise be all formed as that width reduces gradually trapezoidal, or be all formed as that width increases gradually trapezoidal.Thus, by regulating the sense of current of wire in each assembly that magnetizes, particularly, make the sense of current of wire in two often adjacent assemblies that magnetize contrary, thus magnetizer 100 alternately magnetizes to rotor permanent magnet ring 1 in circumferencial direction N pole, S pole.
