Abstract
The utility model discloses a kind of underwater brushless motors, including stator seat, it is provided with rotor on the outside of the stator seat, Exciting Windings for Transverse Differential Protection is installed in the middle part of the stator seat, Exciting Windings for Transverse Differential Protection outer cover is equipped with sealing shroud, there is long axis hole in stator seat, the motor shaft being connect with rotor is installed in the long axis hole, the long axis hole both ends are separately installed with the first, second bearing for supporting the motor shaft.This underwater brushless motor structure can effectively seal Exciting Windings for Transverse Differential Protection, be not necessarily to plus outer seal configuration, is lost with reducing production cost and delivery efficiency, allows motor long-time steady operation under water.
Description
Technical field
The utility model is related to a kind of motor, especially a kind of underwater brushless motor.
Background technology
With the raising of the progress of residential city and life in the countryside level, the demand of building supply equipment is continuous
Rise.Supply equipment experienced in recent years to be pumped from the constant pressure water supply to pipe that separate unit or more centrifugal pumps combine and unit
The evolution of constant pressure water supply.In the prior art, it pumps in pipe and is generally driven using brushless motor, in order to make motor can be with
It works under water, needs to add sealed compartment in outside motor, but this motor need to use movable sealing structure, make motor production cost
It is higher, and increase the frictional resistance between motor shaft and sealed compartment, it is larger to the delivery efficiency loss of brushless motor.
Invention content
The technical problem to be solved by the present invention is to provide a kind of underwater brushless motors, without additional additional seal knot
Structure is lost with reducing production cost and delivery efficiency.
In order to solve the above-mentioned technical problem, a kind of underwater brushless motor of the utility model, including stator seat, the stator
Seat outside is provided with rotor, and Exciting Windings for Transverse Differential Protection is equipped in the middle part of the stator seat, and Exciting Windings for Transverse Differential Protection outer cover is equipped with sealing shroud, stator seat
It is interior that there is long axis hole, the motor shaft being connect with rotor is installed in the long axis hole, the long axis hole both ends are separately installed with use
In the first, second bearing for supporting the motor shaft.
The sealing shroud is sealant pouring and sealing set or stainless steel housing.
The rotor includes the rotator seat with the motor axis connection, and rotor circle is connected on rotator seat, in the rotor circle
Side is equipped with several magnetic links.
The outer end of the rotator seat is provided with the location hole passed through for screw with motor axis connection.
The inner end of the rotator seat is provided with the step surface with the first bearing corresponding matching.
The utility model has the beneficial effects that：In this underwater brushless motor structure, Exciting Windings for Transverse Differential Protection outer cover is equipped with sealing
Set, can effectively seal Exciting Windings for Transverse Differential Protection, be not necessarily to plus outer seal configuration, is lost with reducing production cost and delivery efficiency,
Allow motor long-time steady operation under water.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the utility model.
Specific implementation mode
Referring to Fig.1, Fig. 2, a kind of underwater brushless motor of the utility model, including stator seat 1,1 outside of the stator seat
It is provided with rotor 2,1 middle part of the stator seat is equipped with Exciting Windings for Transverse Differential Protection 3, and 3 outer cover of Exciting Windings for Transverse Differential Protection is equipped with sealing shroud 7, stator seat 1
It is interior that there is long axis hole 11, the motor shaft 4 being connect with rotor 2,11 both ends of the long axis hole difference are installed in the long axis hole 11
The first, second bearing 5,6 for supporting the motor shaft 4 is installed.In this underwater brushless motor structure, outside Exciting Windings for Transverse Differential Protection
Portion is set with sealing shroud, can effectively be sealed to Exciting Windings for Transverse Differential Protection, is not necessarily to plus outer seal configuration, to reduce production cost and defeated
Go out efficiency losses, allows motor long-time steady operation under water.
In the present embodiment, the sealing shroud 7 is sealant pouring and sealing set or stainless steel housing, is had good corrosion-resistant
Performance.The rotor 2 includes the rotator seat 21 being connect with the motor shaft 4, is connected with rotor circle 22 on rotator seat 21, the rotor
It encloses 22 medial surfaces and several magnetic links 23 is installed, the outer end of the rotator seat 21 is provided with to be passed through and motor axis connection for screw
Location hole 24, the inner end of the rotator seat 21 is provided with the step surface 25 with 5 corresponding matching of the first bearing, makes rotor
Positioning between seat, motor shaft and first bearing is more acurrate, and motor operation is more stable.
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 scope of protection of the utility model.
