Background technology
Motor for dryer for many years uses always centrifugal design of electrical motor scheme, and starting torque is big, efficient；But
It carries mechanical centrifugal switch, and the stability of motor is poor, and noise is big, short life；To find common induction machine alternative solution,
Each producer all actively design new punching for dryer motor high starting torque requirement, existing mainstream punching torque performance compared with
It is low, it cannot be satisfied the requirement of dryer complete machine high torque (HT).In order to obtain one seat in customers' place, gesture is promoted in new platform punching
It must go.
Utility model content
The purpose of this utility model is to provide a kind of high starting torque dryer motor stamping, which can fit
It is reasonable for structure for the high starting torque of dryer, it is at low cost.
To achieve the above object, the utility model uses following technical scheme：Including mutually matched stator punching with
Rotor punching, the stator punching is integrally square, and its side length is 124mm, the four corners of the stator punching are using circle
The internal diameter of arc structure, a diameter of 152~158mm of the arc structure, the stator punching is 76~80mm, stator punching
Piece is radially evenly equipped with punching slot, the high 0.6~0.8mm of 2.3~2.5mm of slot opening, notch of the punching slot, slot shoulder height
0.7~0.9mm；The outside diameter of the rotor punching is to match with the interior circular diameter of stator punching, the rotor punching
Radially it is provided with closed slot and ventilation hole.
The closed slot is peariform slot, and the teeth portion width formed between two neighboring peariform slot is equal.
The ventilation hole is sector, and ventilation hole uniform intervals arrange four.
The closed slot is arranged 30~34.
The closed slot is arranged 30.
The punching slot is arranged 24.
It is arc-shaped that the stator punching forms quadrangle by butt processing, and four sides are linear square structure.
As shown from the above technical solution, the utility model greatly reduces copper consumption by the internal diameter of increase stator punching；
Ensure that the width of teeth portion is equal by using the closed slot of pyriform, increases motor torque；It, can by the design of fan-shaped ventilation hole
Increase torque resistant ability, and draught area can be increased, cooling and cost advantage are apparent.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model stator punching；
Fig. 2 is the structural schematic diagram of the utility model rotor punching.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings：
A kind of high starting torque dryer motor stamping as shown in Figure 1, including mutually matched stator punching 1 and rotor
Punching 2, stator punching 1 is whole square, is 124*124mm its side length is 124mm, i.e. the shape X*Y of stator punching 1；It is fixed
The four corners of sub- punching 1 use arc structure, and a diameter of 152~158mm of the arc structure, this refers to foursquare arc structures
The virtual outer diameter of a circle D1 that connection is formed is 152~158mm；The internal diameter of stator punching 1 is 76~80mm, the stator of large diameter
Punching can be such that winding pole span increases, and under equal conditions reduce air gap flux density, while reaching same performance, substantially reduce
Copper consumption；Stator punching 1 is radially evenly equipped with punching slot 11, and the slot opening A of punching slot 11 is 2.3~2.5mm, notch is high
B is 0.6~0.8mm, slot shoulder height C is 0.7~0.9mm；The outside diameter of rotor punching 2 is the interior circular diameter with stator punching 1
It matches, rotor punching 2 is radially provided with closed slot 21 and ventilation hole 22.
Further, closed slot 21 is peariform slot, and the teeth portion width formed between two neighboring peariform slot is equal, teeth portion
24 width is equal, can increase the torque of motor.
Further, ventilation hole 22 is sector, and 22 uniform intervals of ventilation hole arrange four.Ventilation hole 22 is designed to fan
Shape is avoiding the area that ventilation hole is increased while magnetic circuit distribution, and cooling and cost advantage are apparent；Fan-shaped ventilation hole simultaneously
22 torque resistant abilities are stronger, i.e., the deflection that fan-shaped ventilation hole generates under identical torsion is minimum.
Further, closed slot 21 is arranged 30~34, and punching slot 11 is arranged 24.Preferably, the setting of closed slot 21 30
A, the structure of 30 slot of rotor punching is more matched with the structure of 24 slot of stator punching, can effectively reduce motor slot ripples, and the two is matched
The output power and efficiency that motor can be improved are closed, while noise is small.
Further, it is arc-shaped that stator punching 1 forms quadrangle by butt processing, and four sides are rectangular knot linearly
Structure, butt processing can remove non-effective part according to magnetic circuit and improve material in this way in the case where not reducing punching performance
Utilization rate realizes the optimization of cost.
The beneficial effects of the utility model are：1）The internal diameter of stator punching increases, and so that winding pole span is increased, in same item
Reduce air gap flux density under part, while reaching same performance, greatly reduces copper consumption；2）The closed slot of rotor punching uses
Peariform slot keeps the width of teeth portion equal, increases Motor torque；3）The design of fan-shaped ventilation hole, evacuation magnetic circuit increase while distribution
The big area of ventilation hole, cooling and cost advantage are apparent；4）The torque resistant ability of fan-shaped ventilation hole is stronger；5）The utility model
Stator punching and rotor punching be suitable for high starting torque require motor, under conditions of meeting performance, cost advantage is bright
Aobvious, alternative centrifugal switch formula starts motor when necessary.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the protection of the utility model claims book determination
In range.
