Abstract
The utility model relates to a permanent magnet synchronous motor which comprises a shell, a stator winding module, permanent magnets, a rotor core, fixed inserts, gaskets, insert seats and locking pins. Screw holes are machined on the rotor core according to the arrangement mode of the permanent magnets, the insert seats are fixed into the screw holes and are not higher than the external circle of the rotor core, and the permanent magnets are mounted on the surface of the rotor core. The structure of the permanent magnet synchronous motor is greatly simplified, parts are simply machined, the motor is convenient to manufacture and runs stably and reliably, the manufacturing cost of the motor is saved, the permanent magnets are prevented from being thrown out due to excessive centrifugal force in high-speed rotation, flux leakage and cogging of the motor are effectively improved, and the overall performance of the motor is remarkably enhanced.
Description
Technical field
The utility model relates to technical field of motors, particularly a kind of permagnetic synchronous motor.
Background technology
The development of permanent magnetic material, the particularly application of high magnetic energy permanent magnetic material in motor, for the development of magneto with apply and opened up a very wide space, permagnetic synchronous motor is widely used in fields such as robot, Aero-Space, radar antenna, precision electronic device equipment, agricultural equipment, Digit Control Machine Tool, electric automobiles.
The permagnetic synchronous motor system has that volume is little, simple in structure, reliability is high, high control precision, high torque density, good Torque Ripple and low noise characteristics.
Permanent-magnetic synchronous motor rotor permanent magnet mounting means is generally surface-type and plug-in type at present.The surface-type rotor structure divides again convex type and embedded, and wherein the tile shape permanent magnet is pasted on convex type rotor core surface, generally overlaps non-magnetic cylinder or bag without latitude glass tape protection permanent magnet; Embedded is permanent magnet to be embedded or partly embeds rotor core fully, and dual mode all is that permanent magnet breaks away from rotor core when avoiding the motor high speed rotating, but processing technology is complicated, difficulty of processing is large, increase motor cost, strengthened simultaneously gas length, reduced air gap flux density and power density.The plug-in type rotor is because there being larger ferromagnetic material between the magnet, so leakage field is very large, and is difficult to processing, all is present permagnetic synchronous motor usual way with upper type, has limited to a great extent promoting the use of of high performance permanent magnetic synchronous motor.
Spliced stator structure makes it have very high copper factor because of its design feature, is the effective way that improves motor performance, but also because playing design feature, has greatly increased the manufacture difficulty of motor.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and provide leakage field and the slot effect that effectively to have improved motor, reduce motor manufacture difficulty and cost, improve the overall performance of motor and a kind of permagnetic synchronous motor that can high-speed stable running.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of permagnetic synchronous motor is characterized in that, comprises casing, the stator winding module, and permanent magnet, rotor core, fixing inserted block, pad, the inserted block seat, the locking pin, its mounting means is:
Be processed with screw hole by the permanent magnet arrangement mode on the rotor core, the inserted block seat is fixed in the screw hole, is not higher than the rotor core cylindrical, and permanent magnet is installed on the rotor core surface.
Described permanent magnet is with the inserted block seat, fixedly inserted block is fixed in the rotor core surface.
Described fixedly inserted block inserts the locking pin and prevents that fixedly inserted block becomes flexible, and pad is padded on fixedly under the inserted block.
Described stator winding module all has the silicon steel sheet stack of convex-concave structure to form by the both sides of twining enamelled wire.
Compared with prior art, the utility model permagnetic synchronous motor has been simplified electric machine structure greatly, spare and accessory parts processing is simple and easy, make motor easy to make, motor manufacturing cost has been saved in stable and reliable operation, and centrifugal force is crossed the phenomenon that senior general's permanent magnet throws away when having avoided simultaneously because of high speed rotating, effectively improved leakage field and the slot effect of motor, the overall performance of motor has been had significant lifting.
