Right side is equipped with pressure-sensitive, and the pressure-sensitive right side is equipped with commutator, and the end cap is equipped with beryllium copper brush needle, on the beryllium copper brush needle
Coat the brush oil without arc fatty oil；
Rotor shaft through-hole is equipped in the middle part of the end cap, the rotor shaft through-hole is equipped with bearing；The rotor shaft tail end is worn
It crosses and is fixed on bearing inner race；Armature spindle with end cap through-hole direct friction, does not reduce loss, reduces electromagnetic radiation；
The iron core is narrow slot iron core, uses voltage range for the pressure-sensitive of 1.5-6.6V, and the pressure-sensitive material is strontium titanates
It is pressure-sensitive；The commutator material is silver-bearing copper nickel.
Further, the narrow slot iron core is formed by stacking by several rotor core sheet metals, the rotor core sheet metal
The piece number be 23, every rotor core sheet thicknesses are 0.35mm.
The beneficial effects of the present invention are：The electromagnetic radiation of product can greatly be reduced by not increasing any inductance capacitance also
Value, can pass through the EMC certifications in European Union and America.
