Abstract
The motor with the isolated rotor and the isolated stator of the invention isolates the rotor and the stator of an alternating current induction motor or a direct current brushless motor, can be separately arranged at two sides of a non-magnetic conducting material of a product container, and is particularly suitable for household appliances or other instruments and equipment requiring no leakage of the product container, such as a washing machine, a refrigerator, an air conditioner and the like.
Description
The invention belongs to motor and make the field.
Along with the usage quantity of electric household utensils such as the raising of people's living standard, washing machine, refrigerator, air conditioner rises rapidly.In the family expenses washing machine, majority is an impeller type washing machine, generally all adopts single-phase electricity container four-pole motor, after pulley decelerates, drives the impeller rotation by the impeller axle that passes washing tub.For the water in the washing tube is leaked, on the bearing pedestal of impeller axle, adopted rubber seal closely, the frictional resistance of impeller axle is increased, and power consumption rises, can occur after long-term the use sealing ring, V belt, belt pulley wearing and tearing, fault such as wear out, leak.At refrigerator, in small-sized refrigeratings such as the air conditioner cooling machinery, generally all refrigerant compressor and motor are made one, be installed in the hermetically sealed can, reduced volume, simplify the structure.But bring some problems so again: 1. the electric motor overheating amount is difficult for distributing in hermetically sealed can, and heat is sneaked in the refrigerating system, and refrigerating efficiency is descended, and power consumption rises.2. owing to after a variety of causes causes that the winding of motor burns out, must discharging refrigerant during repairing, take hermetically sealed can apart, the expense of taking a lot of work is expected.3. power supply introducing hermetically sealed can and motor winding at high temperature insulate and understand accelerated ageing, and fail safe is descended.
More than generally use the single-phase electricity condenser motor in several household electrical appliance, the detent torque of this class motor is less, electric efficiency generally has only about 40%.In order to make the more household electrical appliance of this class power consumption realize economize on electricity, can adopt novel permanent magnet brushless electromotor, the principle of this motor and design in " permanent magnet brushless electromotor " book that Science Press publishes nineteen eighty-two, have detailed elaboration.
The objective of the invention is to design and a kind ofly can make above-mentioned household electrical appliance solve leakage sealed problem, again Jie Nengjianghao rotor and the stator motor of isolating.
Technical scheme of the present invention is with the rotor and the stator isolation of motor, can be divided in the both sides of product container non-magnet material.This motor can be an induction alternating current (AC) motor, also can be permanent magnet brushless electromotor, and the structure of motor can be that the garden cylindricality motor of interior or external rotor also can be the dish type motor of fixed disk-type rotor.Be the example explanation with brushless, permanently dish type motor now: the rotor of permanent magnet brushless electromotor can adopt whole permanent magnetic material, fill with incorgruous magnetic, also can adopt the p-m rotor of magnetic patch and other rotor materials splicing, the load that this rotor and it are driven is contained in a side of product container non-magnet material.The stator of motor can adopt the disc silicon sheet core, also can adopt the splicing of magnetic patch or several C sections cores.Be wound with stator coil on stator core, the position of the corresponding motor rotor of stator is installed in the opposite side of product container non-magnet material.Leave small running clearance between rotor-side and container non-magnet material, stator side will be close to and be installed on the container non-magnet material, reduces non-magnet material and running clearance shared thickness in magnetic circuit as far as possible, helps improving the efficient of motor.
In the gap of stator or stator rotor-position sensor is housed, the senser of this transducer can adopt the Mageneto-sensitive type element, also can adopt photoelectric cell when non-magnet material is the transparent body, comes the turned position of detection rotor.Send the corresponding signal of telecommunication, through amplifying the rear drive electronic switching element, the power on/off of control stator coil realizes the brushless commutation of magneto.
The motor that rotor of the present invention and stator are isolated can save parts such as deceleration belt pulley, sealing ring, V-belt after implementing on the washing machine, eradicated the seepy question of impeller axle.After implementing on the compressor of refrigerator or air conditioner, stator and coil are contained in outside the compressor seal jar, make the heat of motor no longer enter refrigerating system, improved the refrigerating capacity of compressor, reduced power consumption in a large number, and be convenient to the maintenance of stator coil, and also improved insulation property, improved safety in utilization.The disk type rotor of permanent magnetism or induction structure also can be installed at the back side of the dish type stator of use in refrigeration system, have flabellum on the rotor, doublely make the blower fan on the air conditioner, but simplified structure reduce cost, improve noise.Also can require to use on leak free instrument of product container or the equipment at other.
