Shaft is made up of two spindle noses, and the spindle nose is located in the axis hole in a manner of gap coordinates, and the spindle nose is provided with some
The connection pawl being located in correspondingly in the fixing hole.By design along rotating shaft axially distribution fixing hole mating connection pawl come
The connection of rotor and power output shaft is realized, the existing usual fixed form being pressed together by tight fit is changed, makes
Extruded when must assemble rotor and power output shaft without press, it is easily laborsaving during assembling and also laborsaving when separating, because
Now rotating shaft and power output shaft do not rely on friction caused by deformation, and engagement realizes transmission, fixing hole in other words
Frictional force between connection pawl is without too big.
Preferably, the connection pawl and rotor core form solder joint to link together by soldering.The mode of soldering,
The temperature needed when melting solder joint during dismounting is low.
Preferably, the rotor core be additionally provided with it is some along the axially extending circumferentially distributed magnetic links mounting hole of axis hole,
The magnetic links 1 are located in the magnetic links mounting hole for a pair.The rotor structure of existing motor is SPM structures, i.e. magnet steel
Piece is surface-mount type, and surface-mount type has magnetic links and is easily knocked broken deficiency.The technical program passes through in rotor core
Magnetic links mounting hole is set, magnetic links are arranged in magnetic links mounting hole, so that iron core can be protected to magnetic links
Shield, prevents magnetic links to be knocked.
Preferably, the magnetic links mounting hole is blind hole, the openend of the magnetic links mounting hole be threaded with by
The briquetting for preventing magnetic links from moving axially being pressed on the magnetic links.It can prevent magnetic links from producing axial movement.
Preferably, being provided with magnetic links ejection spring in the magnetic links mounting hole, the magnetic links ejection spring is pressure
Spring, the briquetting can be most short to being retracted to by magnetic links ejection spring press by magnetic links；In magnetic when removing briquetting
Magnetic links can stretch out magnetic links mounting hole more than 5 millimeters in the presence of steel disc ejection spring.It is convenient during magnetic links to take out.And
Axle is produced when will not cause magnetic links by larger axial moving force because the design of magnetic links ejection spring when assembling
To movement.
The utility model tool has the advantage that：It is laborsaving when being attached between rotor and power output shaft, separate rotor and
It is laborsaving during power output shaft.
