Description

Be used for compressor and the motor-compressor bank used at cooling system
Technical field
Relate to a kind of compressor that comprises the motor of variable velocity at this utility model.Said motor also comprises having the coil that distributed winding is connected with T shape coil.
Background technique
The cooling system that is used for dwelling house or commercial building uses the compressor with electric notor so that temperature control usually.Therefore in many these systems, can change hugely for the demand of this compressor (and for motor).Therefore, produced the Several Methods that is used to control and make up motor and compressor.
Given this, the motor of normally used compressor, single-phase or two phases have two kinds of different structures.In this two breeds of horses reached, rotatablely moving produced through the magnetic force in stator and the rotor.Rotor needs moment of torsion to start its rotation, produces moment of torsion through the magnetic force that between the magnetic pole of rotor and stator, forms.The removable magnetic pole of attraction force that between stator and rotor, forms or repulsive force " tractive " or " promotion " rotor, thus the required power of rotor rotation that makes produced.
Yet although the working principle of this motor of two types is identical, their structure is different.Only be called electric notor or having in the first kind of electric notor of brush; Stator has permanent magnet; It produces constant magnetic field, and rotor has and adopts the brush that connects, thereby can received current; Control the magnetic field that changes polarity in rotor, to produce, so that a tractive or promotion rotor according to motor.Though the structure of such motor and control are comparatively simple; But some problems occurred, the quantity of for example setting up the magnetic pole that the speed limit that produces with the wearing and tearing of the brush that interrupts being connected, owing to the generation that causes brush and being connected of power supply spark and electric noise, brush and brush can have framework constitutes the fact of restriction.
Therefore, another type in these electric notors of using always is called brushless electric notor or permanent magnet electric notor.In this motor, magnetic construction is put upside down, and wherein, rotor configuration becomes to have the permanent magnet that produces the stationary magnetic field, and stator has the electrical connection on the brush that before is positioned at rotor.Therefore, the electric current in the stator produces magnetic field, and this magnetic field is also controlled according to motor and changed polarity, so that the rotor of a tractive or promotion permanent magnet.Therefore, between rotor and stator, there is not the physics contact, solved previously mentioned problem; Therefore, in the utility model, preferably use such motor.Understand that importantly this motor has more accurate electric control, proper handling that not only can governor motor, and can regulate its movement velocity under specific circumstances; Its unique shortcoming is that cost of production is higher.
Similarly, explanation is used to control the certain methods of compressor.Be used for one of temperature controlled method and be based on the excitation of the compressor under the specific maximum temperature and the currentless subsequently control of the compressor under specific minimum temperature, like what can be seen in the document US 3,260,064 in the North America.The motor of these types is called switch (ON-OFF) motor, although efficient is low, their simple structure makes that their assembling is easy.Equally, such compressor can use down high-power, and from this reason, in long-time, it is very frequent in cooling, using these motors, and they also are used in the commercial cooling procedure.
On the other hand, be used for the control that temperature controlled other method is based on the rotational speed of motor, the cooling capacity of motor is adjusted to the cooling requirement of system; These motors are called VCC (variable displacement compressor), like the document US 4,856 in the North America; 286 with US 3,803, shown in 865.In this respect, motor is electric control (using the control through inverter usually), therefore has high efficiency.
In addition; Except the durability used with the application scenarios that satisfies high starting torque and more sternness; When comparing with traditional compressor, the compressor of these types comprises: reduce in case they when most of time is moved with low speed, vibrate with average noise level; Owing to can use higher speed, the time that is used for cooling food shortens; Because temperature fluctuation is less, food temperature stability in time is better; The possibility of proper handling when having the great fluctuation process of voltage.
Yet; The use of these motors produces the needs for the certain production line of its structure; Thereby cause the high fixed cost investment aspect equipment and training, and then usually hindered the competitive ability between the cooling system that uses these motors owing to need to recover these costs.
In this respect, normally used in the prior art motor utilization has the three-phase Y shape connection of centralized winding.Therefore, used three main coils, each is by different encouraging mutually.
The model utility content
Therefore, one of purpose of the utility model is with for the production line that makes up before the switch motor institute is adapted to the structure that is used for the VCC motor, thereby attempts to reduce cost of investment, and still keeps level of efficiency and be suitable for the control of VCC motor.
Another purpose of the utility model is to use the compressor of these types to be used for need more powerful commercial cooling.
These purposes are through being used for realizing that at the compressor that cooling system uses said compressor comprises at least: electric controller; Also can control the inverter of motor by said electric controller control; And variable velocity brushless motor; Said motor comprises that also T shape coil connects, and except inferior coil, said T shape coil connection also has main coil; Said main coil has the first portion that is connected to second portion; Said coil is connected to the tie point of first portion and second portion, and said motor also comprises distributed winding, and said distributed winding has the magnetic pole that at least one pair of connection of energy can be provided to said rotor.
Aspect of the utility model, the compressor that is provided in cooling system, using, said compressor comprises at least:
Electric controller;
The variable velocity brushless motor, said motor comprises coil; And
Inverter, said inverter is controlled by said electric controller, and can control said motor;
It is characterized in that said motor comprises the coil that T shape with main coil and time coil is connected, said main coil comprises the first portion that is electrically connected to second portion, and said time coil is electrically connected to said first portion and is electrically connected to said second portion,
Said main coil is constructed to have the distributed winding of at least one pair of magnetic pole.
Aspect another of the utility model, the motor-compressor bank that is provided in cooling system, using, said motor comprises coil, and by inverter control, said stack features is,
Said coil comprises main coil, and said main coil is constructed to distributed winding, and has at least one pair of magnetic pole; Said main coil is divided into first portion and second portion,
