For example China Patent No. ZL 96219006.3, name is called the utility model patent of " motor cooling of small food crusher ", disclosing a kind of inside that comprises is provided with the support of the series excited machine of fan and the small food crusher of bottom, series excited machine is inner or outside at the end cap of commutator end, or be provided with axial flow or centrifugal fan in the end cap inside of clutch end, support arranges ventilation hole on the band eaves, and lower ventilation hole is set in bottom.Although this utility model is provided with fan, but the passage of its cooling blast exists unreasonable structure and inefficient defect, reason is: the series excited machine of this patent is the same with general series excited machine, the cross section of its stator core is also to be designed to routinely rectangle structure, the cross section of casing inside is circular configuration, due within rectangle structure fits over circular configuration, there are four spaces between circle and rectangle, namely four straight flange directions at casing and stator module have produced four gas channels, again because general series excited machine becomes symmetrical a pair of winding by stator design, therefore four gas channels only have two to be of practical significance, two remaining gas channels just play the air draft effect, rotor and stator winding are not produced to the effect directly cooled, not only cause the air-flow waste also to make electric machine temperature rise raise, performance index and the life-span of motor are reduced greatly.
Summary of the invention
The utility model technical issues that need to address are, the series excited machine cooling blast that overcomes prior art wastes because fault of construction exists and makes the too high defect of series excited machine temperature rise, provide a kind of gas channel to the series excited machine fan to be optimized and reasonable disposition, what series excited machine ventilating system efficiency was improved optimizes structure.
The purpose of this utility model is achieved by following technical proposals:
oneplant optimizing structure of series excited machine ventilating system, comprise motor component and fan part, fan part comprises the movable vane wheel and determines impeller, motor component comprises casing and is located at rotor assembly and the stator module in casing, stator module comprises stator and lower stator skeleton, lower stator skeleton is provided with a pair of stator winding caulking groove, it is characterized in that, be provided with baffle plate in lower stator skeleton both sides and stator winding caulking groove position at an angle of 90, baffle plate is sector structure, the internal diameter adaptation of the external diameter of sector structure and casing, the argument of sector structure is 70～110 °.
Electric machine rotation drives the movable vane wheel and rotates, the movable vane wheel rotates the air-flow formed and enter vertically casing after determining the impeller guiding, and blow to rotor and stator module, the major part of air-flow flows to the gas channel between stator module and casing, owing at position, stator skeleton both sides, baffle plate being set, baffle plate covers in two in four passages between stator module and casing, only stay two passages, these two passages face toward a pair of winding of stator module just, and the stator winding topmost thermal source that the motor feels hot just, therefore, cooling blast is just in time to carry out cooling facing to the thermal source that the motor feels hot, so cooling effect is remarkable, air-flow can not waste yet.
As preferably, the outer rim of described sector structure radially is provided with the wedge structure of inclination.
