Description
Technical field
The utility model is related to technical field of motors, more particularly to a kind of cooling system, specifically a kind of be used to cool down
The system of motor stator.
Background technology
The loss that motor is operationally produced translates into heat, in order that the temperature of motor is heat-resisting no more than being insulated from
The corresponding limiting temperature of grade and guarantee motor safety are reliably run, and the type of cooling should be taken it is effectively radiated.Cause
This, the design of electromotor cooling system is critically important in motor technology.
Motor cooling be primarily referred to as using some cooling means and some media to the stator winding of motor, rotor windings with
And the cooling of the progress such as iron core.At present, the conventional motor type of cooling is broadly divided into two kinds of air cooling and water cooling.
Air is cooled down, and is referred to that air is sucked by the fan of rotor both sides, is discharged by designed air channel outside motor, and will
The mode that heat is taken away, wherein, hot-air through motor outside aerial cooler cooling after be re-fed into motor reuse.Due to
The heat transfer coefficient of air is relatively small, therefore cooling effect is unsatisfactory.
At present, the cooling medium that existing motor is applied, about 50 times of air most strong with the cooling capacity of water, cooling
Significantly, in addition, water also has inexpensive, nontoxic and nonflammable feature to effect.The conventional water cooling system of motor is direct
Water channel is opened up in motor case, by being cooled down to motor case, so that next heat not broken belt will be conducted through in motor
Walk.Gap of the heat of motor internal between motor stator core and motor case, is conducted to casing, then again in casing
Water cooling, heat is taken away, or is directly outwards radiated by casing.So, the conduction of motor internal heat is limited, no
The heat that motor operation is produced can be taken away rapidly, electric built-in temperature drop is not got off, and causes copper olse to increase, electric efficiency drop
It is low.
With it is industrial and it is manufacturing develop rapidly, requirement of all trades and professions to power of motor and output torque is also increasingly
Height, therefore, a kind of more efficiently type of cooling be current this area in the urgent need to.
