Embodiment 1
[0049] Such as Figure 1-4 , a winding frame for a slotless brushless motor, the winding frame is a cylindrical frame as a whole; the end faces of the two ends of the cylindrical frame are respectively provided with a plurality of circumferentially distributed wires for winding Wire slot 4 for coil 3;
[0050] The cylindrical skeleton is composed of a winding skeleton main body 2 and 2 soluble winding ends 1 [can also be a soluble winding end]; the soluble winding end is located at the end of the cylindrical skeleton.
[0051] The end of the soluble winding is made of a low-melting-point alloy; the low-melting-point alloy is an alloy with a melting point of 20°C-150°C.
[0052] The main body of the winding frame is made of metal or plastic.
[0053] Such as Figure 3-8 The inner end of the soluble winding end has a protruding part 6, and the end of the main body of the winding frame has a concave part 5 for inserting the protruding part.
[0054] There are 3 wire grooves, ...
Embodiment 2
[0072] Such as Figure 1-4 , a winding frame for a slotless brushless motor, the winding frame is a cylindrical frame as a whole; the end faces of the two ends of the cylindrical frame are respectively provided with a plurality of circumferentially distributed wires for winding Wire slot 4 for coil 3;
[0073] The cylindrical skeleton is composed of a winding skeleton main body 2 and 2 soluble winding ends 1 [can also be a soluble winding end]; the soluble winding end is located at the end of the cylindrical skeleton.
[0074] The soluble winding ends are made of plastic alloy.
[0075] The main body of the winding frame is made of metal or plastic.
[0076] Such as Figure 3-8 The inner end of the soluble winding end has a protruding part 6, and the end of the main body of the winding frame has a concave part 5 for inserting the protruding part.
[0077] There are 3 wire grooves, which are equally divided along the circumferential direction; as Figure 1-8 .

Embodiment 3
[0085] A method for preparing a slotless brushless motor based on the winding frame described in embodiment 1 and embodiment 2, comprising the following steps:
[0086] After the coil is wound on the winding bobbin, the bobbin wound with the coil is inserted into the ring-shaped fixed
[0087] In the sub, and then dissolve the soluble winding end, the main body of the winding skeleton, the coil and the stator are integrally formed,
[0088] Then take out the main body of the winding frame to complete the forming of the stator winding, and finally put it into the motor shell, install
[0089] Insert the rotor, the front and rear bearings of the motor, and the end cover to complete the assembly of the slotless brushless motor winding.
[0090] If the soluble winding end is made of a low-melting alloy material, the soluble winding end is dissolved by putting the enameled wire-wound winding frame into oil or water whose temperature is higher than the melting point of the low-melt...
