Time in working order, centrifugal force makes latch arms 57c be rocked to inoperative position from active position.
When the first external rotor moving coil 5 is vertically near internal rotor rotating disk 9, second external rotor moving coil 7 also corresponding towards the direction of close internal rotor rotating disk 9 move identical distance, thus make the second variable gap 73 between the second external rotor motion copper dish 72 and permanent magnetic disk 91 reduce identical distance along with the reduction of the first adjustable air gap 53 between the first external rotor motion copper dish 52 and permanent magnetic disk 91; As shown in Figure 6, be the minimum situation of air gap.
When the first external rotor moving coil 5 is vertically away from internal rotor rotating disk 9, second external rotor moving coil 7 is also corresponding moves identical distance towards the direction away from internal rotor rotating disk 9, thus make the second adjustable air gap 73 between the second external rotor motion copper dish 72 and permanent magnetic disk 91 increase identical distance along with the increase of the first adjustable air gap 53 between the first external rotor motion copper dish 52 and permanent magnetic disk 91, realize the symmetry adjustment of adjustable air gap 53,73; As shown in Figure 7, be the maximum situation of air gap.
Inner rotor core comprises internal rotor rotating disk 9 and inner rotor shaft 2.Internal rotor rotating disk 9 and inner rotor shaft 2 can be designed to directly be connected vertically.A permanent magnetism group 91 internal rotor rotating disk 9 can be equipped with.When outer rotor shaft 1 rotates, two copper dishes 52,72 also rotate thereupon, because the reason of magnetic force, drive permanent magnetism group 91 to rotate, permanent magnetism group 91 drives internal rotor rotating disk 9 to rotate, thus drives inner rotor shaft 2 to rotate; Permanent magnetism group 91 also can replace with the disc type winding 92 with reference to accompanying drawing 10, on making material more economically.
The utility model outer-rotor type vortex drive device, when being in static or relative static conditions, suction makes external rotor moving coil 5,7 tend to internal rotor rotating disk 9, and separates the minimal air gap of a required condition of work.During startup or emergent stopping, relative velocity between external rotor moving coil 5,7 and internal rotor rotating disk 9 causes the repulsion between permanent magnetism group 91 and metal end face to increase, external rotor moving coil is made to present trend away from internal rotor rotating disk 9, under the effect of now rotor motion dish pull bar 62 outside, the the first external rotor moving coil 5 and the second external rotor moving coil 7 that lay respectively at both sides are synchronously axially displaced, the corresponding air gap of symmetry change, makes it slightly increase to soft-start air gap from minimal air gap.This soft-start air gap makes internal rotor be in lower level of torque, rises to operating rate gradually, thus reduces the impact to relevant starting device, effectively prevent mechanical damage.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
