Description
Technical field
The invention belongs to wheel hub motor manufacturing technology fields, are related to a kind of cooling structure of wheel hub motor, specifically
It is related to a kind of stator water-cooling structure of wheel hub motor.
Background technology
Wheel hub motor is exactly that motor is arranged in the hub in simple terms, is an important directions of Development of Electric Vehicles.
In the design process of wheel hub motor, the problem of temperature rise of motor is to influence the main problem of electric machine operation state.If in motor
The temperature liter in portion is excessively high, can largely reduce the service life of motor insulation material, and the destruction of insulating materials then means motor
It scraps；For magneto, once temperature liter is excessively high, irreversible demagnetization phenomenon, the phenomenon can occur for permanent magnet material
Mean that motor is scrapped.
Traditional type of cooling is that separately plus separate fan, but this mode makes motor volume become larger, reactive loss and noise
It increases, dynamic balancing (or static balance) is difficult, and complex process and cost increase.And for wheel hub motor, due to compact-sized,
Space is small in wheel, so the rational type of cooling is extremely important.
As soon as it is the current effective ways for solving problem of temperature rise, internal rotor wheel hub motor to take away motor heat by flowing water
For, due to its stator and rotor characteristics of compact layout, inside arrange that separate fan is relatively difficult.And the heat source of motor is exactly fixed
It is very limited for cooling down the usable arrangement space of stator institute on son, so the reasonable simple water-cooling structure of design one is to wheel
Hub motor has great importance.
Invention content
The purpose of the present invention is the motor radiating effect for traditional separate fan type of cooling is poor, motor volume is big, nothing
The deficiencies of work(is lost and noise is big, and dynamic balancing or static balance are difficult, and complex process and cost increase, proposes a kind of wheel hub motor
Stator water-cooling structure, by change stator structure, can effectively solve the problems, such as motor temperature rise.
The technical scheme is that：A kind of stator water-cooling structure of wheel hub motor, including stator teeth and stator yoke；
It is characterized in that：It is equipped with several through-holes identical with axis stator direction in the stator yoke, is equipped in the through-hole cold
But water pipe, described cooling water pipe one end are equipped with water inlet port, and the other end is equipped with water outlet port, the cooling water pipe and the through-hole
Form U-shaped connection, the water inlet port of the cooling water pipe and water outlet port, which are stretched out, to be arranged in the same outside of stator, described cold
But water pipe is tightly fastened with the through-hole formation in the stator yoke and connect.
The through-hole is circular through hole, is located on the center line of each stator teeth radial direction.
It is fixedly connected using epoxy glue embedding between the cooling water pipe and through-hole.
The material of the cooling water pipe is copper tube.
Beneficial effects of the present invention are：The stator water-cooling structure of a kind of wheel hub motor provided by the invention, in stator yoke
It is respectively provided with a through-hole relative to each stator teeth, through-hole is located on the center line of stator teeth, rearward in stator yoke
The position of position, through-hole is the blind area of the magnetic line of force, and magnetic conductive area is not influenced, and cooling water pipe is according to U-shaped around by every
A through-hole, cooling water pipe are fitted together closely by epoxy glue embedding and stator, and epoxy glue thermal conductivity is good, make heat dissipation effect more
Good, no need to increase structure novels for motor volume；Compared with traditional separate fan cooling structure, the present invention can make wheel hub motor
Heat dissipation is more uniform, avoids the temperature gradient in axial direction, to improve radiating efficiency, efficiently solves asking for motor temperature rise
Topic.
