Abstract
The invention discloses a variable frequency motor rotor. The variable frequency motor rotor comprises a rotor body, wherein a plurality of magnet slot hole positions are arranged on an end surface of one side of the rotor body along an axial direction thereof and are uniformly arranged along a circumferential inner side of an outer circle of the rotor, magnet discharging holes are formed in the bottoms of the magnet slot hole positions, and two ends of each magnetic discharging hole respectively communicate with an end surface of the other side of the rotor body and the magnet slot hole positions; a cylindrical push rod is also arranged, the push rod is inserted from the magnet discharging hole when a magnet is replaced or taken out, the magnet is directly pushed out of the magnet slot hole position, and thus, installation and replacement are facilitated; the magnet is easy and convenient to install due to the design of the magnet slot hole positions, a magnet mark can be randomly replaced, and the magnet is also stably and firmly installed and cannot be dumped out when stably running with the rotor; and the magnet is installed without an adhesive to fix, thus, the push rod is inserted from the magnet discharging hole during replacement and disassembly, the magnet is directly pushed out of the magnet slot hole position, and installation and replacement are facilitated.
Description
Technical field
The present invention relates to frequency conversion motor technical field, particularly to a kind of frequency conversion motor rotor.
Background technology
Existing frequency conversion motor, rotor outer circle or the inside are fitted with permanent magnet, by the work to hot-wire coil for the magnetic field
With converting electrical energy into kinetic energy, in order to improve motor performance, the mounting means of Magnet and fixation all there is problems：
Using tile-type Magnet, it is bonded on rotor around cylindrical, forms peripheral magnetic field, so in the course of the work, rotor revolves
Turning causes rotor that Magnet is thrown out.
Using metal frame, Magnet is waled, prevent from throwing away at work Magnet, but the manufacture of metal frame is pretty troublesome, precision will
Ask high, lead to cost not bery high；
Using shaping circular ring magnet, cost is very high, be unfavorable for large area produce, and at this stage to high performance cannot
Accomplish that annular manufactures (particularly sintering process)；
Comprehensive above technical problem, is badly in need of the frequency conversion motor rotor that a high-performance, safety and Magnet are easily installed use.
Content of the invention
The technical problem to be solved in the present invention is the variable-frequency electric providing a kind of high-performance, safety and Magnet to be easily installed use
Machine rotor.
In order to solve above-mentioned technical problem, the technical scheme is that：
It is an object of the invention to provide a kind of frequency conversion motor rotor, the installation of its Magnet stably firmly, steady with rotor operation
Surely Magnet will not be thrown out, and the installation of Magnet is easy and convenient, the Magnet trade mark can arbitrarily be changed.
A kind of frequency conversion motor rotor, including rotor body, described rotor body sets along a side end face of its axis direction
There are several Magnet slot hole positions, Magnet slot hole position is uniformly laid along inside rotor outer circle periphery, Magnet is arranged at Magnet and inserts
Slotted eye position；The bottom of Magnet slot hole position is provided with unloads bore, unload bore two ends be respectively communicated with rotor body another side end face and
Magnet slot hole position；It is also equipped with columned push rod, when Magnet is changed or takes out, inserts push rod, directly handle from unloading bore
Magnet releases Magnet slot hole position, and convenient installation is changed；
Preferably, a side end face of Magnet filling entrance is provided with cover plate, and cover plate is can 90 ° of sheet metals bending；Treat magnetic
After ferrum is all filled into Magnet slot hole position, by cover plate, 90 ° bend the sealing of Magnet slot hole position and flatten.
Preferably, described Magnet its orifice chamfer of slot hole position, is easy to Magnet and loads.
Preferably, the size shape number phase of the size shape number of the Magnet slot hole position Magnet to be installed with rotor is fitted
Join.
With respect to prior art, beneficial effects of the present invention are：
A kind of frequency conversion motor rotor of the present invention, the design of its Magnet slot hole position makes the installation of Magnet easy and convenient, magnetic
The ferrum trade mark can arbitrarily be changed, and Magnet install stable firmly, stably Magnet will not be thrown out with rotor operation；Magnet inserts
After Magnet slot hole position, natural adsorber rotor inwall, outside has cell wall to intercept, so under running up, Magnet also will not get rid of
Go out Magnet slot hole position；The installation of Magnet is fixed without glue, so when changing, dismantling, from unloading bore insertion push rod, directly
Magnet is released Magnet slot hole position, convenient installation, replacing.
Brief description
Fig. 1 is a kind of cross-sectional structure schematic diagram of present invention frequency conversion motor rotor.
