Abstract
The invention discloses a self-starting high-efficiency permanent magnet synchronous motor, relates to an improvement of a self-starting high-efficiency permanent magnet synchronous motor structure. The invention provides the self-starting high-efficiency permanent magnet synchronous motor with good self-starting performance and no material restriction. The self-starting high-efficiency permanent magnet synchronous motor comprises a stator core in a housing outside a motor shaft, a winding is arranged outside the stator core; a rotor core with a built-in wiring trough and an end ring outside is arranged in the housing corresponding to the stator core and one end of the housing is a fan. The structure is characterized in that a magnet is arranged between the rotor core and the motor shaft, and the magnet consists of magnetic yokes and permanent magnets which are arranged alternately, and pole shoes are arranged on outer circles of the magnetic yokes.
Description
Technical field:
The present invention relates to the improvement of self-starting permasyn motor structure.
Background technology:
Self-starting permasyn motor has characteristics such as volume is little, self-starting, efficient height, obvious energy conservation, and the market space is widely arranged, but in fact the share that accounts for of market is very few.Main cause is that existing permanent magnet rotor structure can't solve the contradiction between performance and the cost; Existing permanent magnet rotor structure must be used the permanent magnet material of magnetic property excellence, and to realize high performance index, this just makes the cost of motor increase, and the too high user of price is difficult to accept naturally, has directly limited it and has used and promote; And use the cheap permanent magnet material of magnetic property low price, and the improvement of motor energy index is not remarkable, and energy-saving effect is not obvious, sometimes even the basic demand that does not reach relevant national standard, does not allow to come into the market.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides a kind of starting performance good, and is not subjected to the self-starting permasyn motor of materials limitations.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes the stator core in the outer housing of motor reel, and stator core is outward a winding; In being provided with corresponding to stator core in the housing for metallic channel, be the rotor core of end ring outward, end in the housing is a fan, its structural feature is to be provided with gathering magnet between rotor core and the motor reel, and gathering magnet constitutes by yoke is alternate with permanent magnet, and the yoke cylindrical is provided with pole shoe.
Beneficial effect of the present invention:
1, available permanent magnet cheaply:
Because be provided with gathering magnet between the rotor core of invention and the motor reel, gathering magnet constitutes by yoke is alternate with permanent magnet, the yoke cylindrical is provided with pole shoe; Yoke between rotor core and the motor shaft is fully utilized, has strengthened the magnetic field intensity of rotor core greatly; Under the prerequisite that ensures high efficiency, high power factor, can adopt cheap permanent magnet to do permanent magnet rotor structure, reduced the cost of motor of the present invention;
The performance that 2, good self-starting and inhibition vibration are arranged:
Because the present invention is provided with the structure of gathering magnet, but the rotor appropriate design that has electric conductor in making in self-starting, be in operation and suppress the optimum position of vibration, thereby reach good starting effect and suppress oscillation action.

Embodiment:
The present invention includes the stator core 7 in 1 10 outer housing 2 of motor, is winding 9 outside the stator core 7; In being provided with corresponding to stator core 7 in the housing 2 for metallic channel 11, be the rotor core 6 of end ring 14 outward, end in the housing 2 is a fan 3, be provided with gathering magnet 5 between 1 10 on rotor core 6 and the motor, gathering magnet 5 constitutes by yoke 8 and permanent magnet 4 are alternate, and yoke 8 cylindricals are provided with pole shoe 12.
The permanent magnet 4 of gathering magnet 5 is the structure of circular ring type.
Below in conjunction with accompanying drawing structure of the present invention is described further:
Stator core 7 outer windings 9 link to each other with electrical source of power, produce rotating magnetic field; Insert aluminium and/or copper in the metallic channel 11 in the rotor core 6 and be starting sliver 13, starting sliver 13 links to each other with end ring 14 and constitutes the loop and promptly start cage, produces starting torque and damping torque, realization self-starting and high stability; Starting sliver 13 and end ring 14 connect by casting or welding procedure simultaneously and are fixed in the rotor core 6, make starting sliver 13, end ring 14 become a global facility with rotor core 6.
