Abstract

A self-starting permanently-magnetic synchronous motor relates to an improved self-starting permanently-magnetic synchronous motor structure. The utility model provides a self-starting permanently-magnetic synchronous motor, which is provided with the good starting performance and which is not limited by materials. The motor comprises an iron core in a shell outside a motor shaft. A winding is arranged outside the iron core. A rotor iron core, inside which a conductor slot is arranged and outside which an end ring is arranged, is arranged corresponding to the stator iron core inside the shell. A fan is arranged at one end inside the shell. The key point of the structure is as follows that a magnet collector is arranged between the rotor iron core and the motor shaft. The magnet collector consists of magnetic yokes and permanent magnets arranged alternately. Pole terminals are arranged on external circles of the magnetic yokes.

Description

A kind of self-starting permasyn motor

Technical field:

The utility model 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.

The utility model content:

The utility model 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 utility model adopts following technical scheme, and the utility model comprises 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.

The beneficial effects of the utility model:

1, available permanent magnet cheaply:

Because be provided with gathering magnet between the rotor core of utility model 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 the utility model motor;

The performance that 2, good self-starting and inhibition vibration are arranged:

Because the utility model 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 utility model comprises 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.

Pole shoe 12 of the present utility model can be arranged on the both sides or a side of yoke 8.

The permanent magnet 4 of gathering magnet 5 is the structure of circular ring type.

Adjacent pole shoe 12 of the present utility model circumferentially differ degree into 360/p, p is the number of poles of motor.

Below in conjunction with accompanying drawing structure of the present utility model 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.
