The low-temperature motor comprises the stator and a rotor. The stator comprises an epoxy resin layer arranged outside and a stator core arranged inside the epoxy resin layer and winded with a winding. The stator core is composed of stator punching sheets. The stator punching sheets of the stator core are fixedly connected with each other through epoxy resin. According to the utility model, the stator punching sheets of the stator core are fixedly connected with each other through epoxy resin, so that the motor is small in size, safety and reliability are achieved, the speed adjustment is convenient, the efficiency is high, the stator punching sheets are prevented from vibrating, no eddy currents are generated among the stator punching sheets, the heating value is low, and especially, the severe harmful phenomena such as the turn-to-turn short circuit are prevented.
Description
Technical field
The utility model relates to a kind of immersed pump special low temperature motor, relates in particular to a kind ofly can be immersed in stator low temperature electric machine in-200 ° of solution.
Background technology
Liquified natural gas (LNG) needs there is a kind of low-temperature pressure container that can slip into vacuum insulation sealing in conveying and receiving course, it is the latent liquid motor in low temperature immersed pump pump pond, this motor is contained in low temperature immersed pump pump pond with the pump housing is same, temperature in this pump pond remains at-163 ℃～-190 ℃ scopes, and the motor standard of our country is minimum, is applicable to-80 ℃.This motor moves under-190 ℃ of states, rotating speed: 1000RPM～6000RPM/min, frequency control.
Low temperature makes the electromagnetic parameter, insulation of motor, lubricated, material all produce great variety, uses and makes a world of difference with motor under standard ambient temperature.
The stator punching of the stator core of existing motor stator is to be connected and operated in together under low temperature ring mirror by cramp, and due to the distortion of material, that winding insulation easily occurs is destroyed, causes turn-to-turn short circuit.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of immersed pump special low temperature motor with insulation stator is provided
The utility model is to be achieved by the following technical programs:
A kind of immersed pump special low temperature motor with insulation stator, comprise stator and rotor, described stator comprises the outer epoxy resin layer covering and is located at the stator core that epoxy resin layer inside is wound with winding, described stator core is comprised of stator punching, affixed by epoxy resin between the stator punching of described stator core and stator punching.
It comprises described rotor mouse cage and is located at the interior rotor core with skewed slot of mouse cage, described rotor core is comprised of rotor punching, affixed by epoxy resin between the rotor punching of described rotor core and rotor punching, described mouse cage comprises and is arranged on oxygen-free copper sliver in rotor core skewed slot and is located at sliver two ends and oxygen-free copper end ring that sliver rivet welding is fixing.
The beneficial effects of the utility model are:
Due to affixed by epoxy resin between the stator punching of stator core and stator punching, motor volume is little; Safe and reliable; Speed governing is convenient; Efficiency is high; Stator punching does not produce vibration; Between sheet, do not produce eddy current; Caloric value is little; Particularly can not produce violent harmful phenomenons such as turn-to-turn short circuit.

When making stator, first, by laminating the stator punching of moulding, with epoxy resin, flood, just affixed by epoxy resin between the stator punching of stator core and stator punching, after firmly insulating barrier to be formed, hyperthermia drying, then put into liquid nitrogen K cryogenic treatment.In punching, all evenly enclose like this one deck insulating epoxy, solved Insulation Problems and guaranteed that again low temperature is indeformable.Can carry out rule winding.With this, guarantee the insulation of winding to punching, guaranteed the insulation property of motor.After stator built-in line completes, with the poured with epoxy resin of low temperature, to guarantee solidifying, dispel the heat and effectively preventing turn-to-turn short circuit of winding.
When making rotor, rotor punching is laminated to moulding with laminating tire, be then immersed in epoxy resin, hyperthermia drying after a hour, then put into liquid nitrogen K cryogenic treatment.Rotor punching is all evenly enclosed one deck insulating epoxy like this, has solved Insulation Problems and has guaranteed that again low temperature is indeformable.
Oxygen-free copper sliver is inserted in the skewed slot of rotor core, rivet welding is carried out at the two ends that then two oxygen-free copper end ring are placed on respectively to rotor core.Effectively prevent oxygen-free copper bar failure.
This structural electromotor volume is little; Safe and reliable; Speed governing is convenient; Efficiency is high; Stator punching does not produce vibration; Between sheet, do not produce eddy current; Caloric value is little; Particularly can not produce violent harmful phenomenons such as turn-to-turn short circuit.
