Description
Technical field
The present invention relates to motor cooling technology field, particularly a kind of thermal diffusivity motor.
Background technology
Motor can produce substantial amounts of heat when running at high speed, and motor must be cooled down at this time, to avoid because
Accident caused by motor temperature rise overrate.And as the lifting of power of motor density, requirement of the motor to heat dissipation are also got over
Come higher, the loss of especially centralized winding electric machine rotor is big, and the heat of generation is big, and magnet steel demagnetization easily occurs, influences electricity
The use of machine, and reduce the performance of motor.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of thermal diffusivity motor.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of thermal diffusivity motor, including stator and rotor, the stator outside are provided with tubular element, are opened in the tubular element
There is the oil cooling chamber of annular, be provided with the tubular element into oil outlet, wave groove is provided with the oil cooling chamber.
As a preference, oil cooling chamber is divided into several shoe cavitys by the oil cooling intracavitary equipped with separating part, described
Opening is left on separating part makes each shoe cavity be interconnected.
As a preference, the opening of the separating part is located at separating part end, and the opening of the adjacent separating part
Stagger position.
As a preference, convex ribs are provided with the tubular element, the end set of the convex ribs has mounting hole.
It is described that oil outlet edge is provided with plane circle as a preference.
The beneficial effects of the invention are as follows：The motor coordinates the wave groove of oil cooling chamber to set by setting oil cooling chamber in tubular element
Meter, substantially increases the heat dissipation effect of motor, improves the work efficiency of motor, improve reliable under motor high-speed working condition
Property.
