Abstract
The utility model discloses a disc motor, which has a main shaft, a stator and a rotor. The utility model is characterized in that the stator fixed in a casing is in a disc shape, the disc-shaped rotor arranged on the main shaft is positioned on the side surface of the stator. The utility model has the advantages that the utilization rate of materials is high, the structure is simple, the mould expense is small, the slip ratio is big, the performance of speed regulation is good, the safety operation is assured, when the utility model is used in a fan, the mechanical loss is small, the efficiency of the fan is high, the utility model is particularly small in size and is thin in thickness, and the utility model can specially be matched with a thin air conditioning fan. In addition, the utility model satisfies the restriction requirement of the air conditioning fans of high rise building to volume and thickness.
Description
The utility model relates to the motor in the technical field of electric appliances, is a kind of disc-type electric motor of thin type.
Motor is to use electric equipment very widely.Existing motor all is radial structure usually, and the casing of a tubular is promptly arranged, and is rotor in the embedded son that sets of casing, stator.These existing motor, its silicon steel sheet utilance is low, generally has only 60%, and its reason is that leftover pieces are many.Production efficiency is low, because of stator, rotor core all need be washed into the disk shape, laminates and buckles and make.Operation is many, and die cost is big.Speed adjusting performance is poor, because of its revolutional slip little.During the variable voltage control operation, electric current obviously increases, and speed governing is not obvious again, and long-time running is unreliable, even can burn motor.Conventional motors is installed impeller by shaft extension, can not reach the requirement of blower fan thin thickness.
The purpose of this utility model provides that a kind of volume is little, simple in structure, the disc-type electric motor of thin thickness, the big good speed adjustment features of revolutional slip.
Technical solution of the present utility model is: a kind of disc-type electric motor, main shaft, stator and rotor are arranged, and it is characterized in that: the stator that is fixed in the casing is a plate-like, is loaded on the side that disc-like rotor on the main shaft is positioned at stator.
The flute profile of the stator described in the utility model, rotor distributes radially, embeds winding in the stator slot; Rotor is a cage type cast aluminium structure, and forms certain skewed slot.Stator, rotor expose, draught fan impeller and rotor direct connection, and the screw that a breasting stator axis is stretched the both ends of the surface setting connects with blower fan.The embedding filler is arranged between stator winding and casing.Certainly, also can adopt other suitable version.
The utility model has the advantages that: the stock utilization height, simple in structure, die cost is little, revolutional slip is big, good speed adjustment features, assurance safe and reliable operation, mechanical loss is little when being used for blower fan, fan efficiency is high, particularly little, the thin thickness of volume, can to aim at slim air-conditioning draught fan supporting, satisfies the requirement for restriction of skyscraper air-conditioning draught fan to volume, thickness.Be used to be applicable to air-conditioning, the building trade special occasions is transformed as market, hospital, reduces space requirement.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing is the structural representation of a kind of disc-type electric motor of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.In this embodiment, a casing is arranged, be fixed with stator core 2 in the casing, stator core 2 is a plate-like, is loaded on the side that disc-like rotor 5 on the main shaft 4 is positioned at stator core 2.Stator, rotor are selected for use good non-directional cold-rolling silicon steel band to dash volume and are formed, and the flute profile of stator, rotor distributes radially, embeds winding in the stator slot; Rotor is a cage type cast aluminium structure, and forms certain skewed slot.Form disc air gap, axial magnetic field between stator, rotor.Stator, rotor expose, draught fan impeller and rotor 5 direct connections, and the screw that a breasting stator axis is stretched the both ends of the surface setting connects with blower fan.Main shaft 4 is supported in the bearing 3.Use vacuumizing method between stator winding and casing, the embedding filler makes the electrical machine insulation reliable in quality, has improved the product degree of protection, has improved the radiating condition of grade.
