Abstract
The utility model relates to a motor rotor, which comprises a body and a magnet steel, wherein the rotor outer surface is evenly provided with a plurality of dovetail grooves, each two adjacent dovetail grooves form a heave of a sector section, the sector heave is provided with extending groove, the magnet steel is positioned in the dovetail groove, the extending groove is provided with a bolt to firmly fix the magnet steel in the dovetail groove. The utility model is stable in magnet fixing function and uneasy to fall out.
Description
Technical field
The utility model relates to a kind of motor, specifically is a kind of rotor of motor.
Background technology
Stator and rotor are motor two big main parts, the big multiple stators of motor commonly used at present adopts coil windings as magnetic pole, be used as magnetic pole and be provided with magnet steel in the rotor outer rim, it is epitrochanterian that magnet steel normally adopts glue to be bonded in, after this motor uses a period of time, the phenomenon that the rotor surface magnet steel comes off often takes place in the rotor high-speed rotary course, influences the operate as normal of motor.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor, and the magnet steel of rotor outer rim is fixed on the outer rim of rotor by the mode of inlaying extruding, and it is reliable to have the magnet steel fixed form, the characteristics of difficult drop-off.
The utility model is by the following technical solutions:
A kind of rotor, comprise body and magnet steel, it is characterized in that: have several equally distributed dovetail grooves at the rotor outer fringe surface, between two adjacent dovetail grooves, form the cross section naturally and be fan-shaped projection, on fan-shaped projection, also have the expansion groove, magnet steel is placed in the dovetail groove, has an expandable nail that magnet steel firmly is fixed in the dovetail groove in the expansion groove.
The utility model is embedded in magnet steel in the dovetail groove of rotor outer fringe surface, and expand fan-shaped projection by expandable nail, thereby magnet steel tightly is fixed in the dovetail groove, guarantees that magnet steel can not drop from rotor surface when rotor high-speed rotates, reliability and fail safe when improving machine operation.
Description of drawings
Fig. 1, structural representation of the present utility model;
Fig. 2, the utility model perspective exploded view.
Embodiment
As shown in Figure 1, 2, a kind of rotor, comprise body 1 and magnet steel 2, evenly have several dovetail grooves 11 at the rotor outer fringe surface, between two adjacent dovetail grooves 11, form the cross section and be fan-shaped protruding 12, also have expansion groove 13 on fan-shaped protruding 12, magnet steel 2 is placed in the dovetail groove 11, thereby has an expandable nail 3 to make fan-shaped projection expansion that magnet steel 2 firmly is fixed in the dovetail groove in the expansion groove 13.
The fixed form of the utility model magnet steel 2 adopts the fashion of extrusion of dovetail groove 11 interface arrangments and expansion groove 13 to fix jointly, when guaranteeing magnet steel 2 with the rotor high speed rotating, the interface arrangment of dovetail groove 11 can not thrown away by centrifugal force, and expansion groove 13 squeezing actions, guaranteed that dovetail groove 11 is more reliable with the snap fit of magnet steel 2, simultaneously also prevented moving axially of magnet steel 2, from comprehensive assurance magnet steel 2 reliability of fixation.
