Description
Technical field
The utility model relates to the double-deck stand structure of a kind of motor, belongs to the electromechanics technical field.
Background technology
Because the loss meeting produces heat, untimely the distributing of this heat influences electric property and is easy to cause motor by scaling loss the motor stator and rotor when operation.Conventional motors adopts the air/water cooler cooling, its Heavy Weight, and overall dimension is big; And air/water cooler places the bottom or the top of casing, and the motor heat is to a direction transmission, the heat transfer circuit path length, and thermal resistance is big, and radiating efficiency is lower.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of motor double-deck stand structure, its good cooling results and compact conformation.
The technical solution of the utility model is as follows: the double-deck stand structure of a kind of motor, comprise airtight casing, end cap is installed at two ends at casing, the rotor that stator is set in casing and rotates with respect to stator, fan is installed on rotor, described casing is the double seal core structure, the axle of described rotor is by stretching out in the end cap inner bearing of casing two ends, in the cavity of described fan between casing and end cap, in the interlayer of described casing ventilation duct is set, the import of described ventilation duct and outlet are stretched out from the two ends of casing interlayer, the import of described ventilation duct is near fan, in the interlayer of casing, 4 dividing plates are set along the direction that is parallel to it, be respectively first dividing plate, second partition, the 3rd dividing plate and the 4th dividing plate, wherein an end of second dividing plate and the 4th dividing plate is provided with breach, the 3rd dividing plate is provided with breach away from an end of the breach of second dividing plate, and the both sides of described first dividing plate are provided with cooling liquid inlet and cooling liquid outlet respectively.
Adopt technique scheme, electric machine stand is the double seal core structure, ventilation duct is set in the interlayer, in the casing interlayer mobile cooling fluid is housed during the motor operation, the heat that motor stator winding and iron core produce reaches the interlayer casing by heat conduction and is taken away by cooling fluid, the heat that rotor winding and iron core produce is also taken away by cooling fluid by the ventilation duct that circulated air enters in the interlayer, thereby realizes the heat exchange of motor.Because cooling fluid is surrounded motor stator core equably, the heat transfer efficiency height, motor circumferentially has a narrow range of temperature.This structure casing can effectively reduce overall dimension, and the tight Minato of structure alleviates complete machine weight.
In technique scheme, described cooling liquid inlet and cooling liquid outlet are positioned at the top of casing, also are provided with leakage fluid dram in the bottom of casing.
Beneficial effect: the utility model is reasonable in design, simple in structure, implement easily, good heat dissipation effect, casing are in light weight.
