Iron, guide sleeve is set, the edge of the armature is arranged on guide sleeve, and the stator leans between the stator and the installing plate
Groove is provided with to the end face of armature, spring is installed in the groove, the spring one end is installed on armature, the axle sleeve to be subtracted
Make an uproar shell fragment.
Optionally, the axle sleeve is prism.
Optionally, the end face of the axle sleeve is regular hexagon.
Further, the side of the axle sleeve is equipped with shell fragment mounting groove, the noise abatement shell fragment close to the side of two end faces
For double barb types, the noise abatement shell fragment is buckled on shell fragment mounting groove.
Further, cave in form a fixed angle among the noise abatement shell fragment.
Optionally, 2 noise abatement shell fragments are installed on the axle sleeve.
Further, the side of a prism is at least spaced between described two noise abatement shell fragments.
The utility model embodiment provide have silencing function without excitation brake, by being no excitation brake
Rotor adds noise abatement shell fragment with shaft room, realizes the feelings for being eliminated in release and noise being likely to occur under high speed rotation state
Condition.This is simple in construction, and cost is cheap, and economic benefit protrudes, and has fully met functional requirement.
