Abstract
The utility model discloses a magnetic steel type outer rotor which is simple in structure and convenient to produce and install, and cost-saving. The magnetic steel type outer rotor comprises an end cover and an iron ring fixed on the end cover, wherein the end cover is arranged on a shaft by a bearing, a fixed bracket is arranged on the inner wall of the iron ring, a plurality of magnetic steel sheets are arranged in the fixed bracket at intervals, the fixed bracket is a circular ring body, and the axial length of the circular body is larger than the length of the magnetic steel sheet; a plurality of magnetic steel sheet placing slots are arranged on the fixed bracket side by side; and the magnetic steel sheet placing slots are positioned in the axial middle position of the fixed bracket. According to the magnetic steel type outer rotor, the motor outer rotor of an electric vehicle is simple in structure, the magnetic steel sheets are easily assembled, as the width of the magnetic steel sheet placing slots is equal basically to that of the magnetic steel sheets, the magnetic steel sheet are subjected to larger clamping force when the magnetic steel sheet are placed in the magnetic steel sheet placing slots, thus ensuring that the magnetic steel sheet can not fall or slant before being adhered.
Description
Technical field
The utility model relates to a kind of rotor structure in electric vehicle motor field, especially a kind of magnet steel formula external rotor.
Background technology
External rotor is the important component part of electric vehicle motor, and itself and stator combination constitute the main part of motor together jointly.
Shown in Fig. 1 to 4, electric vehicle motor magnet steel formula external rotor of the prior art comprises through bearing 101 being installed in the end cap 103 on the axle 102 and being fixed on the iron ring 104 on the end cap 103 that iron ring 104 inwalls are provided with a plurality of magnetic links 105; Be provided with two fixed supports 106 on iron ring 104 inwalls in opposite directions, this fixed support 106 comprises annular stent base 107, is arranged at intervals with a plurality of support arms 108 on the bracket base 107, and support arm 108 is along the axial convexity of bracket base 107; Magnetic links 105 is installed on the fixed support 106, and its two ends withstand on respectively on the bracket base 107, and 108 intervals of supported arm between two magnetic links 105.
Above-mentioned magnet steel formula external rotor of the prior art; When fixing magnetic links, at first a fixed support 106 is fixed on iron ring 104 inwalls; Then magnetic links 105 is inserted in the support arm 108; Again another fixed support 106 symmetries are enclosed within on iron ring 104 inwalls, with glue magnetic links 105 and fixed support 106 are bonded on the iron ring inwall at last.
In installation process, when a magnetic links was inserted between two adjacent support arms, its active force that receives was the support force straight up that bracket base applies its bottom, and two support arms of these magnetic links both sides are to its chucking power.Because support arm be along the axial convexity of bracket base, its area that contacts with magnetic links is less, and this just makes chucking power deficiency that receives after the magnetic links insertion, on fixed support, drops easily or tilts, and makes troubles to installation.
In addition; The motor outer rotor of this structure, magnetic links is installed needs two fixed supports, so just must in two steps two fixed supports be installed in respectively on the iron ring inwall in the installation process; Its production and processing operation is loaded down with trivial details; Installation steps are complicated, make that the production efficiency of this external rotor is lower, and its production cost are higher.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, production and easy for installation, and the magnet steel formula external rotor of saving cost.
For addressing the above problem; A kind of magnet steel formula external rotor of the utility model comprises end cap and is fixed on the iron ring on the end cap, and end cap passes through Bearing Installation on axle; The iron ring inwall is provided with fixed support; A plurality of magnetic links are arranged in the fixed support at interval, it is characterized in that: said support bracket fastened body is a torus, and the length on this torus is axial is greater than the length of magnetic links; On said torus fixed support, offer several magnetic links standing grooves side by side; Said magnetic links standing groove is positioned at the axial centre position of fixed support.
The thickness that said torus directly makes progress is less than the thickness of magnetic links.
All apart from being opened on the torus, the width of its width and single magnetic links is basic identical for said magnetic links standing groove.
Said fixed support is that non-magnetic conductive material is processed.
Said non-magnetic conductive material is a plastic material.
Adopt the magnet steel formula external rotor of the utility model, when fixing magnetic links, at first the torus fixed support is fixed on the iron ring inwall, then magnetic links is inserted in the magnetic links standing groove, with glue magnetic links and fixed support are bonded on the iron ring inwall again.
In terms of existing technologies; The magnet steel formula external rotor of the utility model structure, simple in structure, magnetic links is easy to assembling; Because the width and the magnetic links of magnetic links standing groove are basic identical; When therefore being placed on magnetic links in the magnetic links standing groove, magnetic links receives bigger chucking power, thereby guarantees that it can not drop or tilt before bonding; Adopt the fixed support in the utility model structure simultaneously, only need an installation of just enough accomplishing whole magnetic links, reduced operating procedure, improved production efficiency, and this fixed support is easy to process, thereby has practiced thrift cost.

Embodiment
In order to make those skilled in the art person understand the utility model technical scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and execution mode.
Like Fig. 5, shown in 6, a kind of magnet steel formula external rotor of the utility model comprises through bearing 201 being installed in the end cap 203 on the axle 202 and being fixed on the iron ring 204 on the end cap 203 that iron ring 204 inwalls are provided with a plurality of magnetic links 205.
The material of said fixed support 206 is a plastic material, also can be other non-magnetic conductive materials.
On said torus fixed support 206, offer several magnetic links standing grooves 207 side by side; The width of magnetic links standing groove 207 is basic identical with the width that is placed on single magnetic links wherein.
Said several magnetic links standing grooves 207 are groove, all apart from being opened on the torus, and are positioned at fixed support 206 middle parts.
