Description
Technical field
The utility model is related to a kind of motor, especially a kind of pump 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 the change from the constant pressure water supply that separate unit or more centrifugal pumps combine to water pump and unit in recent years
The evolution of frequency constant pressure water supply.In the prior art, water pump generally uses the motor of inner rotor core, and the torque of motor is small,
Heat dissipation effect is poor, is easy to happen failure.
Invention content
The technical problem to be solved by the present invention is to provide a kind of pump motors, and there is high torque and good heat radiating to imitate
Fruit, it is not easy to break down.
In order to solve the above-mentioned technical problem, a kind of pump motor of the utility model, including stator seat, outside the stator seat
Side is provided with rotor, and Exciting Windings for Transverse Differential Protection is equipped in the middle part of the stator seat, has long axis hole in stator seat, is installed in the long axis hole
There is the motor shaft being connect with rotor, the motor cover that rotor is surrounded is installed on stator seat, motor is provided with outside the motor cover
Shell, forms water stream channel between the motor casing and motor cover, the stator seat has the first water stream channel mouth, the motor casing
One end is connected and fixed with stator seat, and the motor casing other end has the second water stream channel mouth.
The motor casing other end is equipped with the connecting seat of perforation.
The long axis hole both ends are separately installed with the first, second bearing for supporting the motor shaft.
There is cable channel, the cable channel one end to lead to the Exciting Windings for Transverse Differential Protection, cable channel is another in the stator seat
It holds exposed.
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 utility model has the beneficial effects that：Outer-rotor structure is used in this pump motor, makes motor that there is larger torsion
Square and great heat radiation effect, and water stream channel is formed between motor casing and motor cover, allow motor directly as water pump pipe
A body part, is not necessarily to additionally mounted tube body, can simplify water pump structure, reduces production cost.
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 pump motor of the utility model, including stator seat 1,1 outside setting of the stator seat
There are rotor 2,1 middle part of the stator seat that Exciting Windings for Transverse Differential Protection 3 is installed, there is long axis hole 4 in stator seat 1, installed in the long axis hole 4
There is the motor shaft 5 being connect with rotor 2, the motor cover 6 that rotor 2 is surrounded is installed on stator seat 1, the 6 outside setting of motor cover
There is motor casing 7, form water stream channel 9 between the motor casing 7 and motor cover 6, the stator seat 1 has the first water stream channel mouth
10,7 one end of the motor casing is connected and fixed with stator seat 1, and 7 other end of motor casing has the second water stream channel mouth 11.This water
Use outer-rotor structure in pump motor, make motor that there is high torque and great heat radiation effect, and motor casing and motor cover it
Between form water stream channel, allow motor directly as a water pump tube body part, be not necessarily to additionally mounted tube body, water pump can be simplified
Structure reduces production cost.
In the present embodiment, 7 other end of the motor casing is equipped with the connecting seat 8 of perforation, 4 both ends of the long axis hole difference
The first, second bearing 12,13 for supporting the motor shaft 5 is installed, electric machine structure is made more to stablize.The stator seat 1
Interior that there is cable channel 14,14 one end of cable channel to lead to the Exciting Windings for Transverse Differential Protection 3,14 other end of cable channel is exposed, electric wire
It is easier to install and safeguard across cable channel.
In addition, the rotor 2 includes the rotator seat 21 being connect with the motor shaft 5, rotor circle is connected on rotator seat 21
22, which is equipped with several magnetic links 23, simplifies rotor structure, and more conducively product is installed.
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.
