Abstract
The utility model discloses a motor for a petrol pump, comprising a stator and a rotor; the rotor is arranged in the stator, and the inner wall of the stator is provided with more than two pieces of magnetic shoes; one of two side edges of each magnetic shoe is thinner than the middle part of the magnetic shoe, and the thin side edges of the magnetic shoes are arranged at one side of the cut-over direction of the rotor after the rotor is rotated. With the structure provided by the utility model, the magnetic field intensity for rotor reversing is reduced, the resistance for rotor reversing is lowered, and the working efficiency of the motor is increased.
Description
Technical field
The utility model relates to motor, particularly the petrol pump motor.
Background technology
The effect of petrol pump is gasoline sucking-off from fuel tank, and is sent in the float chamber of carburetor with gasoline filter by the road.Just because of petrol pump has been arranged, petrol tank just can be placed to the automobile tail away from engine, and is lower than engine.The petrol pump petrol pump can be divided into two kinds of Mechanical Driven diaphragm type and driven types by the difference of type of drive.The Mechanical Driven diaphragm gasoline pump generally drives by the eccentric wheel on the camshaft, and driven type comes work by the motor impeller.Existing motor is made of stator, rotor, on the inwall of stator magnetic shoe is installed, and the thickness of magnetic shoe equates that the magnetic line of force between the adjacent magnetic shoe is bigger.When rotor rotated, because the magnetic line of force, the incision resistance of rotor was big, had increased the resistance of commutation, had reduced the efficient of motor self.
Summary of the invention
The purpose of this utility model provides a kind of petrol pump motor, and technical problem to be solved is the magnetic field intensity that reduces the rotor commutation, reduces rotor commutation resistance, improves the operating efficiency of motor.
For achieving the above object, the petrol pump motor comprises stator, rotor, and rotor is located in the stator, and stator inner wall is provided with the magnetic shoe more than two; A wherein side of magnetic shoe dual-side is thinner than the interior thickness of magnetic shoe, and the thin side of magnetic shoe is positioned at postrotational incision direction one side of rotor.
As specializing, the in axial direction cut back of the medial angle of a wherein side of magnetic shoe dual-side forms the thin side of above-mentioned magnetic shoe.
As improvement, the cross section of the thin side of magnetic shoe is triangular in shape.
As improvement, the both sides that are positioned at magnetic shoe on the inwall of stator are provided with magnetic shoe and buckle.
The beneficial effects of the utility model are: because the wherein side of magnetic shoe dual-side is thinner than the interior thickness of magnetic shoe, like this, few at the magnetic line of force of incision place of rotor, magnetism intensity is little, has therefore reduced the resistance of rotor commutation, has improved the operating efficiency of motor.Owing to be provided with the magnetic shoe button, therefore, be convenient to install and fixing magnetic shoe.
Description of drawings
Fig. 1 is the cutaway view of petrol pump with motor.
Fig. 2 is the cut-away view of petrol pump with motor.
Fig. 3 is the enlarged drawing among Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Petrol pump motor as depicted in figs. 1 and 2, comprise stator 1, rotor 2, the inwall of stator 1 is provided with magnetic shoe and buckles 4, be equipped with magnetic shoe 3 on the magnetic shoe button 4, the in axial direction cut back of the medial angle of a wherein side of magnetic shoe dual-side forms the thin side 31 of above-mentioned magnetic shoe, and the cross section of the thin side of magnetic shoe is triangular in shape.The thin side of magnetic shoe is positioned at postrotational incision direction one side of rotor.
Because the wherein side of magnetic shoe dual-side forms thin side, like this, few at the magnetic line of force of incision place of rotor, magnetism intensity is little, has therefore reduced the resistance of rotor commutation, has improved the operating efficiency of motor.Owing to be provided with the magnetic shoe button, therefore, be convenient to install and fixing magnetic shoe.
