1) this utility model reasonable in design, moving axially by combined cover, connect or cut off the first combination gear
Transmitting with the power of the second combination gear, needs permanent-magnet speed buffer works when, combined cover combines tooth to second vertically
Wheel is mobile, connects the first combination gear and the second combination gear, it is achieved power from the first combination gear to the second combination gear
Transmission；Need not permanent-magnet speed buffer work when, combined cover moves to the first combination gear vertically, disconnects the first combination
Gear transmits to the power of the second combination gear；Solve what general permanent-magnet speed buffer brought because of leakage field in a non-operative state
Power consumption problem.
2) by being respectively separated, on stator and rotor, the permanent magnet being provided with equal number, and permanent magnet is near armature spindle axis
The most identical structure of end face magnetic, it is ensured that stator and rotor are constantly in the state attracted each other, and rotor is relative to stator
Any rotation permanent magnet of being required for overcoming stator to be provided with and the permanent magnet that is provided with of rotor between mutual attractive force, and
On stator and rotor adjacent surface, captivation between permanent magnet is much larger than the power of tradition permanent-magnet speed buffer permeability magnetic material cutting magnetic induction line.
Traditional permanent-magnet speed buffer is obtained by the way of permeability magnetic material cutting magnetic induction line braking moment become by permanent magnet it
Between directly attract each other and obtain braking moment, be effectively increased braking moment, in the case of obtaining identical braking moment, greatly
Decrease greatly the quantity using permanent magnet, save cost.
