Description

Method and device for setting winding connection mode of series excited motor and series excited motor

Technical Field

The application relates to the technical field of motors, in particular to a method and a device for setting a winding wiring mode of a series excited motor and the series excited motor.

Background

The stator winding wire of the series excited motor for the drum washing machine has two forms of serial connection and parallel connection at present, and has advantages and disadvantages. In the temperature rise test, the motor power in the form of parallel winding is increased to 1.06 times of rated voltage according to national standard, and the motor temperature rise test is difficult to pass because the motor power in the form of parallel winding is increased too much when the voltage is increased, so that the current series connection is the main wiring form of the stator winding.

The series connection mode has the defects that the output power of the motor is low, the motor cannot meet the requirements on a large-capacity washing machine with the output power of 10Kg or more or a washing machine with the ultra-high dehydration rotating speed (more than or equal to 1500 rpm), and if the motor is matched, the cost of iron cores and winding materials is required to be greatly increased, the cost performance of the motor is reduced, and the market competitiveness is reduced. Under the condition that the cost of the motor material is not obviously increased, a stator winding parallel connection scheme with larger output power is adopted, and the motor washing temperature rise test under the rated voltage of 1.06 times cannot pass.

In view of the above problems, no effective solution has been proposed at present.

Detailed Description

Embodiments of the present embodiment will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present embodiments are illustrated in the accompanying drawings, it is to be understood that the present embodiments may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided to provide a more thorough and complete understanding of the present embodiments. It should be understood that the drawings and the embodiments of the present embodiments are presented for purposes of illustration only and are not intended to limit the scope of the embodiments.

For better understanding of the embodiments of the present application, technical terms related in the embodiments of the present application are explained below:

series excited machines, also known as series excited machines, are a type of dc motor.

The motor winding is divided into a full winding and a half winding, and the difference between the full winding and the half winding is the connection mode of the windings. In the full winding, two ends of each coil are directly connected with a slot of a motor to form a complete circuit; in the half winding, two coils in the slot are respectively connected with other coils on different wafers in parallel, so that two sections of circuits are formed. Therefore, the number of coils of the half winding is only half that of the full winding.

In the related art, the problem that the series excited motor stator winding for the drum washing machine is insufficient in output power in a serial connection mode and the motor temperature rise test in a parallel connection mode is difficult to pass exists. In order to solve the problem, the embodiment of the application provides a stator winding mixed wiring mode, and the wiring mode firstly ensures that the stator working windings of the drum washing machine are connected in series in a washing state, so that the problem that the washing temperature rise of the pure parallel windings exceeds the standard under the rated voltage of 1.06 times of national standard is successfully solved; secondly, the stator working windings are connected in parallel in a high-speed dehydration state, so that the problem of low output power of the simple windings connected in series is successfully solved.

In addition, the following three points are considered in the design process: 1. the winding slot filling rate designed is considered to be suitable for production; 2. consider meeting the requirements of national standard 0.85 times rated voltage starting; 3. in the state of the dehydration program, how to realize the conversion from the series connection low-speed operation to the parallel connection high-speed operation of the windings. The following is a detailed description.

All washing machines are characterized in that: in the washing operation mode, the rotating speed is low, the operation time is long, and the heat dissipation condition of the motor is poor; in the high-speed dehydration operation mode, the rotating speed is high, the operation time is short, and the heat dissipation condition of the motor is good. This feature results in the highest temperature rise of the motor of the washing machine often occurring in the washing stage.

Fig. 1 shows a schematic diagram of a series connection of stator windings of a motor for a washing machine, where U and Z respectively represent full windings of two poles (N pole and S pole), U includes windings U1 and U2, Z includes windings Z1 and Z2, the wire diameters of the two poles winding are identical to the number of turns of the full winding, and the tap number of turns are identical, i.e., u=z, u1=z1, u2=z2, and the method is suitable for executing a two-pole pair winding production mode with higher winding efficiency. The colors of the working winding leads are the same, namely, the working winding leads are red and brown; high-drop, red and gray working winding leads.

As shown in fig. 1, the series connection mode of the stator windings is shown, and the two-pole working windings are as follows: when washing and low-speed dehydration are carried out, the full windings U and Z are connected in series and are connected with current to participate in operation; during high-speed dehydration, the U2 and Z2 tap windings on the two poles participate in operation work and are still connected in series.

The series connection has the advantages that when the power supply voltage is increased, the current increase amplitude is smaller, the loss increase of the motor is smaller, and the temperature rise increase is not large; the disadvantage is that the output power is smaller, and the motor with higher dehydration rotating speed requirement is difficult to meet.

Fig. 2 shows a schematic diagram of a parallel connection wire of a stator winding of a motor for a washing machine, as shown in fig. 2, the parallel connection wire of the winding, the two pole working windings of which are: when the windings are washed and dehydrated at a low speed, the full windings U and Z are electrified in parallel to participate in operation; during high-speed dehydration, the U2 and Z2 tap windings on the two poles participate in running work and are still connected in parallel.

The parallel connection has the advantages of outputting larger power, and being suitable for motors with higher dehydration rotating speed requirements; the disadvantage is that when the power supply voltage rises, the current increases greatly, the loss of the motor increases more, and the temperature rise of the motor is difficult to meet the requirement.

According to the working characteristics of the washing machine, the advantages of the two connection modes of series connection and parallel connection of the stator windings of the series excited motor of the conventional drum washing machine are combined, and a mixed connection mode is provided. And according to the influence duty ratio experience of the wire diameter and the turns of the stator winding on the main performance of the motor, the temperature rise and the moment, the proper wire diameter is selected, and the slot filling rate is reasonable in design, so that the existing equipment and tools can be utilized for production and manufacturing.

According to an alternative embodiment of the present application, there is provided a series motor for use in a washing apparatus, comprising: the washing equipment comprises two full windings, wherein each full winding in the two full windings comprises an inner ring winding and an outer ring winding, when the washing equipment operates in a washing mode, the inner ring winding of a first full winding in the two full windings is connected in series with two windings in the second full winding in the two full windings and is electrified to operate, and the outer ring winding of the first full winding is not electrified; when the washing equipment operates in a high-speed dehydration mode, the outer ring winding of the first full winding is connected with the outer ring winding of the second full winding in parallel, and is electrified to operate, and the inner ring winding of the first full winding and the inner ring winding of the second full winding are not electrified.

The washing winding of the series excited motor is characterized in that two-pole stator windings participating in the operation are of an asymmetric structure, namely, the number of turns of one pole (full winding Z) of the washing winding participating in the operation is large, and the number of one pole (winding U1) is small.

The stator windings of the series excited motor are connected in series when the washing machine washes, so that the phenomenon that the temperature rise of 1.06 times rated voltage exceeds standard caused by the parallel connection mode of the windings is avoided.

In the embodiment of the application, when the washing machine is in the high-speed dehydration operation mode, the tap windings U2 and Z2 on the two poles participate in the operation work and are connected in parallel. When the low-speed dehydration is performed to the high-speed dehydration, namely when the winding U1+Z series form is converted to the parallel U2+Z2, the magnetic field direction is unchanged, namely the motor steering is unchanged, and smooth switching is realized.

The high-winding-removal winding of the series excited machine is characterized in that the stator winding which participates in the operation is in a symmetrical structure, namely the two poles (windings U2 and Z2) of the high-winding-removal winding which participates in the operation have the same number of turns.

In the embodiment of the application, in the series excited motor, in the design of realizing the series connection of washing working windings and the parallel connection of high-release working windings, the stator tap winding of one of the two poles is shared, the enameled wire is reasonably utilized, and the material waste can be avoided.

When the washing machine dewaters at a high speed, the stator windings of the series excited motor are connected in parallel, so that the problem of insufficient output power caused by the mode of connecting the windings in series is solved.

In some alternative embodiments of the present application, a dust cover is provided on the bearing of the series motor, the dust cover being out of contact with the inner windings of the two full windings.

In a preferred embodiment, the bearing of the series excited motor adopts a non-contact type iron cover type of the dust cover and the inner ring winding, which is different from a large-scale use of contact type rubber cover bearing, reduces the running friction loss of the motor and is beneficial to the realization of high-speed running of the motor.

In addition, in the specific implementation process, equipment tools required by the production of the series excited motor are special for the special design of the punching sheet. At present, a series excited motor for a washing machine is gradually replaced by a brushless direct current motor (BLDC motor), and development and design of a new high-efficiency series excited motor punching sheet are not cost-effective. The specific embodiment is as follows:

the lamination adopts the mass production of the series excited motor 63 lamination of the washing machine, the core lamination thickness adopts the mass production of 52mm, and any die and tooling are not required to be added.

The rotor adopts a mass production scheme, is universal, and avoids the management cost of separately manufacturing and turning parts.

The wire diameter of the motor stator winding adopts a production specification, no new material number is generated, the material purchasing and management are facilitated, the winding process adopts a production double-package opposite winding mode with taps, and workers are skilled in operation without additional training.

The series excited motor provided by the embodiment of the application can be applied to existing punching sheets, equipment and tools, and the performance requirement of the required motor can be realized on the basis of zero investment. The stator winding wiring of the series excited motor is comprehensively connected in series and in parallel, mixed wiring is carried out, the working windings are connected in series during washing and are connected in parallel during high-speed dehydration, and meanwhile, the motor realizes smooth conversion from low-speed dehydration of the windings in series to parallel high-speed dehydration during dehydration.

U1 and Z1 are inner windings, and U2 and Z2 are outer windings.

When the washing machine is in a washing or low-speed dewatering operation mode, the windings U1 and Z (full windings) are electrified in series to participate in the operation work, and the winding U2 is not electrified to participate in the operation work.

When the washing machine is in a high-speed dehydration operation mode, the tap windings U2 and Z2 on the two poles participate in the operation work and are connected in parallel. When the low-speed dehydration is performed to the high-speed dehydration, namely when the winding U1+Z series form is converted to the parallel U2+Z2, the magnetic field direction is unchanged, namely the motor steering is unchanged, and smooth switching is realized.
