Abstract
The utility model belongs to the technical field of water pump motors and in particular relates to a novel motor with a compact structure. The novel motor comprises a motor shell made of an insulating material, wherein a rotor and a stator are arranged in the motor shell; two ends of a rotating shaft of the rotor are respectively arranged on front and rear bearing mounting seats of the front and rear walls of the motor shell through bearings; the front bearing mounting seat and the bearing are connected through a bearing block insert made of metal; and the front end of the bearing block insert is connected with a grounding protection wire. The novel motor has the advantages that the motor shell and the front bearing mounting seat are made of insulating material, and the bearing block insert is arranged between the front bearing mounting seat and the bearing, so that the distances between the stator and the motor end cover and between the stator and the front bearing mounting seat are greatly reduced, and the heights of the motor end cover and the front bearing mounting seat do not need to be increased due to the requirement of the creepage distance; and therefore, the motor is more compact in structure.
Description
Technical field
The utility model belongs to the pump motor technical field, refers in particular to a kind of New-type electric machine of compact conformation.
Background technology
At present, the water pump design all need be considered the problem of creepage distance, and the water pump that certain structures is compact can not reach requirement because of the design of motor enamelled wire height production ratio is high in subsequent production, and product design can't be changed.Take a kind of new electric machine structure to solve the problem that motor produces because of creepage distance inadequately in the case.
Summary of the invention
It is reasonable that the purpose of the utility model provides a kind of product structure, the New-type electric machine of the compact conformation of the compound standard of creepage distance.
The purpose of the utility model is achieved in that a kind of New-type electric machine of compact conformation; Include the electric machine casing that insulating material is processed; Rotor and stator are installed in the electric machine casing; The two ends of the rotating shaft of rotor are passed through Bearing Installation respectively on the forward and backward Bearing Installation seat of electric machine casing front and rear wall, accept through metal bearing pedestal inserts between front bearing mount and the bearing, and the leading section of bearing pedestal inserts is connected with the ground protection line.
Above-mentioned rear bearing shaping socket for installation is on the rear wall of electric machine casing, and front bearing mount that insulating material is processed and electric machine casing are split-type structural.
Above-mentioned insulating material is plastics.
Above-mentioned bearing pedestal inserts is sleeved on the outside of bearing and is installed in the front bearing mount.
The utility model is compared the outstanding and beneficial technical effects of prior art:
Electric machine casing of the utility model and front bearing mount are that insulating material is processed; Accept through metal bearing pedestal inserts between front bearing mount and the bearing; The leading section of bearing pedestal inserts is connected with the ground protection line; The enamelled wire that only needs to guarantee stator can not cause the enamelled wire clashing and breaking because of contacting with electric motor end cap and bearing pedestal; Dwindled the spacing of Stator and electrical machine end cap and front bearing mount, needn't increase the height of electric motor end cap and front bearing mount, made that the structure of motor is compact more because of the requirement of creepage distance.

Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1;
A kind of New-type electric machine of compact conformation; Include the electric machine casing 5 (electric machine casing comprises front motor end cap 51 and rear motor end cap 52) that insulating material is processed; Rotor 4 and stator 3 are installed in the electric machine casing 5; The two ends of the rotating shaft 8 of rotor 4 are installed on the forward and backward Bearing Installation seat of electric machine casing 5 front and rear walls (1,6) through bearing 7 respectively, accept through metal bearing pedestal inserts 2 between front bearing mount 1 and the bearing 7, and the leading section of bearing pedestal inserts 2 is connected with the ground protection line.
Above-mentioned rear bearing mount pad 6 is molded on the rear wall of electric machine casing 5, and the front bearing mount 1 that insulating material is processed is split-type structural with electric machine casing 5.
Above-mentioned insulating material is plastics.
Above-mentioned bearing pedestal inserts 2 is sleeved on the outside of bearing 7 and is installed in the front bearing mount 1.
Electric machine casing 5 and bearing pedestal (1,6) all adopt plastic material to process that (rear bearing mount pad 6 is molded on the rear end inwall of electric machine casing 5; Front bearing mount 1 is a split-type structural with electric machine casing 5); The enamelled wire that only needs thus to guarantee stator (stator is a winding iron core) can not cause the enamelled wire clashing and breaking owing to contacting with electric machine casing 5 and front-end bearing pedestal 1; Can the spacing of stator and front and back electric motor end cap (51,52) and front-end bearing pedestal be contracted to minimum, needn't increase the height of electric motor end cap and bearing pedestal because of the requirement of creepage distance.Simultaneously, for solving the problem of rotor ground connection, accept through metal bearing pedestal inserts 2 between front bearing mount 1 and the bearing 7, the leading section of bearing pedestal inserts 2 is connected with the ground protection line.
The foregoing description is merely the preferred embodiment of the utility model, is not the protection range that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection range of the utility model.
