Description
Technical field
The present invention relates to brushless direct current motor, more particularly to overall oil-immersed type dc motor, belong to electric motor for pump technical field.
Background technology
At present, the motor of brshless DC motor is typically all split design with controller, outfield need to first fix motor and controller respectively when installing, then plug and socket between motor and controller is installed, split type motor and controller have the deficiencies such as gross weight is heavier, the cumbersome, area occupied of installation is big；Dynamic sealing is carried out by leather cup between motor and load pump, motor internal not immersion oil, leather cup is consumable accessory, its short life, and quality of fit requirement is high, so as to increase the difficulty of processing of motor ball bearing.
The content of the invention
In view of the foregoing defects the prior art has, the present invention is intended to provide a kind of simple and compact for structure, easy for installation, reliability overall oil-immersed type dc motor high.
To achieve these goals, the present invention uses following technical scheme, including motor body and the motor body rear end cap to be fastened together the controller of structure；It is electrically connected and static sealing using sealed sintering connector between the motor body and controller；The bearing of the motor body is graphite bearing.
The sealed sintering connector includes that quad seal sinters connector and circular seal sintering connector.
O-ring seal is provided with the controller housing.
The controller is fastened with motor body rear end cap by screw.
The motor body is made up of oil resisting material.
Beneficial effects of the present invention are as follows：
Motor body of the present invention is structure as a whole with controller, and outfield installs simple and convenient, compact overall structure, main screw lift greatly reduces；Motor runs in may be dipped in aviation kerosine, is not required to carry out dynamic sealing between motor and load pump, so as to eliminate the application of consumable accessory leather cup, increased the reliability of whole system, reduces the difficulty of processing of motor shaft.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the A-A structural representations of Fig. 1；
Fig. 3 is the B direction schematic diagrams of Fig. 1；
In figure：Motor body 1, motor body rear end cap 1-1, graphite bearing 2, O-ring seal 3, controller 4, quad seal sintering connector 5, circular seal sintering connector 6.
Specific embodiment
With reference to specific embodiment, the invention will be further described：
As shown in Fig. 1 ~ 3, including motor body 1 and motor body rear end cap 1-1 are fastened together the controller 4 of structure；It is electrically connected and static sealing using sealed sintering connector between motor body 1 and controller 4, the bearing of motor body 1 is graphite bearing 2, graphite bearing has very strong adaptability to kerosene, will not be corroded by kerosene, the housing of controller 4 carries out static sealing using O-ring seal 3, covered installed in motor rear end by screw, realize that controller 4 is integrated with motor body 1, reaching whole electric system can be fully immersed in the requirement run in aviation kerosine.
The sealed sintering connector includes that quad seal sinters connector 5 and circular seal sintering connector 6.
The controller 4 is fastened with motor body rear end cap 1-1 by screw, and plays fuse.
In order that motor runs in may be dipped in aviation kerosine, motor body 1 is made of oil resisting material, without carrying out dynamic sealing again between motor and load pump, can cancel leather cup, increased the reliability of whole system, reduces the difficulty of processing of motor shaft.
