Description
Technical field
The utility model relates to a kind of draining pump field frame assembly, and particularly a kind of permanent magnet synchronous drainage pump field frame assembly mainly is applicable to washing machine, dishwasher.
Background technology
The drain motor of washing machine, use in dishwasher all adopts permagnetic synchronous motor at present, it is to adopt U-shaped structure iron core that this motor has individual outstanding feature, but the drum stand that cooperates with it is the centre bending structure, as shown in Figure 1, after the bending U-iron core is penetrated in the endoporus of drum stand.Because two end faces that drum stand contacts with the U-iron core are docking, there is certain slit in contact-making surface, causes easily the creepage distance between iron core and the enamelled wire inadequate in the more situation of enamelled wire winding, causes that easily motor punctures.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, breakdown characteristics strong, make assembling and be easy to the permanent magnet synchronous drainage pump field frame assembly, to overcome weak point of the prior art.
A kind of permanent magnet synchronous drainage pump field frame assembly by this purpose design; comprise stator core, drum stand, coil windings, terminal and protector; wherein; stator core takes the shape of the letter U; stator core passes drum stand; terminal is arranged on the drum stand; coil windings is wrapped on the drum stand; the lead-out wire at coil windings two ends is welded on the terminal; protector is fixedly connected with terminal or drum stand; its architectural feature be stator core the U-shaped bottom surface simultaneously and the first end face of drum stand and the second end face fit, the first end face and the second end face are in the same place being in contact with one another location overlap.
The front end of described the first end face overlap the second end face front end top or below.
The front end of the front end of described the first end face and the second end face is triangular in shape in the cross section that is in contact with one another, rectangle, ellipse, parallelogram or trapezoidal.
The thickness of the front end of the front end of described the first end face and the second end face is 0.1～3mm.
The front end of the front end of described the first end face and/or the second end face is the above veneer of one deck.
The thickness of described veneer is 0.1～3mm.
The front end of the front end of described the first end face and the second end face is triangular in shape in the cross section that is in contact with one another, rectangle, ellipse, parallelogram or trapezoidal.
The utility model is in the situation of the structural dimensions that does not change drum stand, by changing the drum stand interface into overlay structure by docking structure, thereby strengthened the creepage distance between stator core and the enamelled wire, improved the breakdown characteristics of motor, promoted the fail safe of product; Simultaneously, the highest number of turn of coil windings design can be promoted, increased the selectivity of design.
The utlity model has simple and reasonable, breakdown characteristics strong, make assembling and be easy to characteristics.
