Description

A kind of punching applied to range hood motor

Technical field

The utility model relates to motor field, especially a kind of punching applied to range hood motor.

Background technique

According to China's range hood national standard, to ensure (i.e. fume-exhausting under range hood maximum static pressure and standard condition Machine exhaust air rate is in 7m2/min) static pressure and efficiency meet national standard, and range hood motor generally uses 120 iron core diameter of Φ 24 slot, 4 pole conceptual design.But this kind of motor maximum quantity of wind operating point revolutional slip is larger (generally >=0.3), and range hood is most When working under static pressure under big static pressure and standard condition, motor slip ratio is smaller (generally less than 0.15), for take into account range hood this Two operating points refer to that range hood motor main phase winding needs larger line footpath to guarantee (to turn in maximum quantity of wind operating point When rate is larger) temperature rise is met the requirements, while needing appropriate increase rotor aluminium ring to guarantee the maximum static pressure and mark of range hood Quasi- operating condition static pressure (when i.e. revolutional slip is smaller) and efficiency are met the requirements, and it is that main winding line footpath is big that such motor, which is typically designed, encloses number More, auxiliary winding line footpath is relatively small, and circle number is few, but the slot opened in the existing punching applied to range hood motor is entirely big It is small uniform therefore inconvenient when electric machine winding, need a kind of novel motor stamping.

Utility model content

To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of structure is simple, it is not only suitable for fume-exhausting The motor of machine, and facilitate the punching of main winding and auxiliary winding coiling.

The utility model be solve its technical problem and the technical solution adopted is that:

A kind of punching applied to range hood motor, comprising:

Punching main body offers a rotor hole at the medium position of the punching main body；

At least one set of slot group, the slot group are set to the position that the punching main body closes on the outer peripheral edge of the rotor hole Place；

Wherein, the slot group includes sulculus group and large trough group, and the sulculus group is made of more than one sulculus, described big Slot group is made of more than one large trough.

As an improvement of the above technical solution, four groups of slot groups are provided in the punching main body, four groups of slot groups are around described Rotor hole is circumferentially uniformly distributed.

As a further improvement of the above technical scheme, the sulculus group includes two sulculuses, and the large trough group includes four A large trough.

Preferably, the quantity of large trough is twice of quantity of sulculus in the slot group.

Further, the area of section of the sulculus is the 70-80% of the area of section of large trough.

Further, the area of section of the sulculus is the 75% of the area of section of large trough.

Wherein, offered in the outer peripheral sidewall of the punching main body one along the punching main body axial direction extend it is recessed Slot.

One preferred embodiment of the utility model, the groove are an arc groove.

The beneficial effects of the utility model are: since the utility model in punching main body by being provided at least one set of slot Group, the slot group include the sulculus group being made of more than one sulculus and the large trough group that is made of more than one large trough, because This user in the stator core using the punching of the utility model when embedding the wire, line footpath is larger, circle number is more main winding and master Slot group can be uniformly embedded into large trough pair altogether, and the auxiliary winding that line footpath is smaller, circle number is less can be uniformly embedded into sulculus, be passed through Above-mentioned embedding scheme can make major-minor winding copper factor evenly distributed, reduce stator built-in line difficulty.

Detailed description of the invention

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Fig. 1 is the surface structure schematic diagram of one preferred embodiment of the utility model；

Fig. 2 is the top view of one preferred embodiment of the utility model；

Fig. 3 is the structural schematic diagram of sulculus in one preferred embodiment of the utility model；

Fig. 4 is the structural schematic diagram of large trough in one preferred embodiment of the utility model.

Specific embodiment

Referring to figs. 1 to Fig. 4, a kind of punching applied to range hood motor, including a punching main body 10, the punching master A rotor hole 11 is offered at the medium position of body 10；At least one set of slot group, the slot group are provided in the punching main body 10 It is set at the position for the outer peripheral edge that the punching main body 10 closes on the rotor hole 11；Wherein, the slot group includes sulculus group With large trough group, the sulculus group is made of more than one sulculus 21, and the large trough group is made of more than one large trough 22.? In the utility model, it is preferable that the area of section of the sulculus 21 is the 70-80% of the area of section of large trough 22.It is further excellent Choosing, the area of section of the sulculus 21 are the 75% of the area of section of large trough 22.

Since the utility model includes by one by being provided at least one set of slot group, the slot group in punching main body 10 The sulculus group that above sulculus 21 is constituted and the large trough group being made of more than one large trough 22, therefore user is practical using this The main winding and major-minor that when embedding the wire on the stator core of novel punching, line footpath is larger, circle number is more, which are total to slot group, to be uniformly embedded into In large trough, and line footpath is smaller, the less auxiliary winding of circle number can be uniformly embedded into sulculus, can be with by above-mentioned embedding scheme So that keeping major-minor winding copper factor evenly distributed, stator built-in line difficulty is reduced.

Herein, for the ease of making the motor of the punching using the utility model can have better performance, as One preferred embodiment of the utility model is provided with four groups of slot groups in the punching main body 10, and four groups of slot groups are around the rotor Hole 11 is circumferential to be uniformly distributed.Further preferably, the quantity of large trough 22 is twice of quantity of sulculus 21 in the slot group.As this One specific embodiment of utility model, the sulculus group include two sulculuses 21, and the large trough group includes four large troughs 22.

Wherein, it is positioned for the ease of the punching of the utility model, it is preferable that opened in the outer peripheral sidewall of the punching main body 10 The groove 12 extended equipped with one along the axial direction of the punching main body 10.Further preferably, the groove 12 is that an arc is recessed Slot.

Referring to Fig. 3 and Fig. 4, for the ease of producing corresponding sulculus 21 and large trough 22 in punching, herein, as The specific size of one preferred embodiment of the utility model, the sulculus 21 and large trough 22 is as follows:

The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means The technical solution of purpose belongs within the protection scope of the utility model.
