Each phase of stator winding is provided with a connecting end which is used for being electrically connected with the outgoing line, so that internal current of the stator winding is realized. It should be noted that, when a stator winding of one phase is formed by winding a copper wire, the connection end of the stator winding is the free end of the copper wire. If a phase stator winding is formed by winding two copper wires, the connecting end of the stator winding is the free end of the two copper wires. Specifically, when the stator winding is a three-phase stator winding, the three-phase stator winding is sequentially nested on the stator core along the radial direction of the stator core. Specifically, each phase stator winding is wound on the stator core along the circumferential direction of the stator core. Furthermore, the number of the connecting ends of the at least three-phase stator winding is at least three, and the at least three connecting ends are dispersedly arranged on the axial end face of the motor.

It is worth mentioning that the connecting ends and the connecting terminals of the stator winding do not coincide with each other in the axial direction.

In one possible design, further, the at least three-phase stator winding includes three-phase stator windings, the connection ends of the three-phase stator windings respectively form three connection lines with the center of the stator core, and an included angle between any two of the three connection lines is not equal to 0 °.

Specifically, the star connection method is to connect one end of each phase of stator winding to one point, and the other end of each phase of stator winding is used as a leading-out wire, namely three phase wires. Star connection, the line voltage is 3 times the root of the phase voltage, and the line current is equal to the phase current. The star connection method is usually used for a motor with low power and large torque or a motor with high power when starting because of low starting output power, so that the loss of the machine is low, and the delta connection method is used after the normal work. The delta connection method is that stator windings of all phases are sequentially connected end to end, and each connected point is led out to be used as three phase lines of three-phase electricity.

When the current in the stator winding is constant, the current in the stator winding is shunted through at least two leads, so that the wire diameter of the outgoing line can be reduced, namely, when the outgoing line is a lead, the wire diameter of the lead is inevitably required to be thicker when one lead needs to bear larger current.

It is worth to be noted that the number of stator windings in the motor is three, and the three-phase stator windings are different phases. The phase-missing problem of the motor means that when any one phase of stator winding in the three-phase stator winding cannot be effectively connected with the wiring terminal, namely, the outgoing line connected with the stator winding falls off from the wiring terminal, the phase-missing problem of the original three-phase motor can occur, and the motor cannot work normally.

The utility model provides a motor 100 includes stator core 110, at least three-phase stator winding 120 and at least three lead-out wire 130. Specifically, the stator core 110 is formed by laminating a plurality of stator laminations.

Each phase stator winding 120 has a connection end for electrical connection with the outgoing line 130, thereby realizing a current passing through the stator winding 120. It should be noted that, when a phase stator winding 120 is formed by winding a copper wire, the connection end of the stator winding 120 is the free end of the copper wire. If a phase stator winding 120 is formed by winding two copper wires, the connection end of the stator winding 120 is the free end of the two copper wires. Specifically, when the number of the stator windings 120 is three, the three-phase stator windings 120 are sequentially nested on the stator core 110 in the radial direction of the stator core 110. Specifically, each phase stator winding 120 is wound on the stator core 110 in the circumferential direction of the stator core 110. Further, the number of the connection ends of the at least three-phase stator winding 120 is at least three, and the at least three connection ends are dispersedly disposed on the axial end face of the motor 100. It should be noted that the dispersed connection means that at least three connection terminals are dispersed and disposed at each of the axial end faces of the motor 100, and at least three-phase connection terminals are not collectively disposed. The motor 100 further includes lead-out wires 130, the number of the lead-out wires 130 corresponds to the number of the stator windings 120 one-to-one, that is, one lead-out wire 130 corresponds to one phase of the stator windings 120, with respect to one lead-out wire 130, one end of the lead-out wire 130 is electrically connected to the connection end of the stator winding 120, and the other end of the lead-out wire 130 can be connected to the connection terminal 220 of the compressor 200.

It is worth noting that the connecting ends of the stator windings 120 and the extension lines of the connection terminals 220 in the axial direction do not coincide.

Further, as shown in fig. 1, at least three-phase stator windings 120 are provided, the connection ends of the three-phase stator windings 120 respectively form three connection lines with the center of the stator core 110, and an included angle between any two of the three connection lines is not equal to 0 °.

In this embodiment, the motor 100 is a three-phase motor 100. The three connection ends of the three-phase stator winding 120 are A, B, C, the center of the stator core 110 is O, the three connection lines are AO, BO and CO, and an included angle formed by any two connection lines in the three connection lines is not 0 °. That is, when the three-phase stator winding 120 is sequentially nested on the stator core 110 along the radial direction of the stator core 110, the three connecting ends are not located on the same radius, so that interference between the plurality of outgoing lines 130 can be avoided, the problem of the wiring process of the outgoing lines 130 is further solved, the production efficiency is improved, and the reliability and the service life of the motor 100 are improved.

It is noted that the stator winding 120 is star-connected or delta-connected. Specifically, the star connection is such that one end of each phase stator winding 120 is connected to one point, and the other ends thereof are used as lead-out lines 130, which are three phase lines, respectively. Star connection, the line voltage is 3 times the root of the phase voltage, and the line current is equal to the phase current. The star connection method is usually used for a motor 100 with low power and large torque or a motor 100 with larger power when starting because of low starting output power, so that the loss of the motor is smaller, and the delta connection method is used after the motor works normally.

For example, the connection terminals 220 of the compressor 200 are disposed at one side (left or right side) of the stator core 110, and at this time, the connection ends of at least the three-phase stator windings 120 may be disposed at the left or right side of the axial end of the stator core 110 near the connection terminals 220.

Example two

Based on the first embodiment, the specific structure of the outgoing line 130 is further described in this embodiment, as shown in fig. 1, fig. 3 and fig. 5, further, the outgoing line 130 includes at least two leads 131, and the at least two leads 131 are respectively connected to the connection ends of the stator winding 120.

In this embodiment, the lead-out wires 130 include at least two lead wires 131, and each of the at least two lead wires 131 is connected to the connection end of the one-phase stator winding 120. When the current in the stator winding 120 is constant, the current in the stator winding 120 is divided by at least two leads 131, so that the wire diameter of the lead 130 can be reduced, that is, when the lead 130 is one lead 131, the wire diameter of the lead 131 is necessarily required to be thicker if one lead 131 needs to carry a larger current. However, if the number of the leads 131 is at least two, the at least two leads 131 can divide the current, and the current flowing through each lead 131 is small, and the wire diameter requirement for the lead 131 is reduced. The hardness and stress of the lead 131 having the small wire diameter are reduced, and when the lead 131 having the small wire diameter is connected to the connection terminal 220 of the compressor 200, it is possible to prevent the difficulty in assembling due to the excessive hardness of the lead 130 and to effectively prevent the lead 130 from falling off from the connection terminal 220 due to the excessive stress of the lead 130.

Further, as shown in fig. 1 and 3, the outgoing line 130 further includes a connection portion 132, the connection portion 132 being provided on each of the at least two leads 131, the connection portion 132 being for connection with the connection terminal 220.

In this embodiment, the lead-out wire 130 further includes a connection portion 132, the connection portion 132 being provided at an end portion of each of the leads 131, the leads 131 being connected to the connection terminal 220 through the connection portion 132. By providing the connection portion 132 at the end of the lead wire 130, the connection reliability between the lead wire 131 and the terminal block 220 can be ensured. In the high-speed operation process of the motor 100, the problem of reliability such as phase loss and even burning loss of the motor 100 caused by falling of the lead 131 due to severe vibration is avoided. It is noted that the number of stator windings 120 in the motor 100 is three, and the three-phase stator windings 120 are different phases. The phase loss problem of the motor 100 means that when any one of the three-phase stator windings 120 is not effectively connected to the connection terminal 220, that is, the outgoing line 130 connected to the stator winding 120 falls off from the connection terminal 220, the phase loss problem occurs in the original three-phase motor 100, and the motor cannot work normally.

It should be noted that the positioning member 140 may be any one or any combination of sleeves or straps. In a specific assembling process, after the connection ends of the lead wires 130 and the stator windings 120 are welded, the positioning member 140 is disposed at the connection position of the two.

Further, the positioning member 140 is an insulating member.

In this embodiment, the positioning member 140 is an insulating member, and the lead wires 130 and the stator winding 120 are connected together by using the insulating member, so that the safety hazard caused by the contact of the connection ends of the lead wires 130 and the stator winding 120 with the stator core 110 is avoided. Specifically, the positioning member 140 is a polyester tie wrap.
