Slotless resolver, method for manufacturing same, and wiring tool used therefor

A winding tool used in a method of manufacturing a slotless resolver, the winding tool comprising:

• a shaft;
• a winding cylinder having the shaft inserted into the winding cylinder and maintained on an outer circumference surface of the shaft at a specific interval;
• and
• a plurality of first slot pins and second slot pins detachably combined with the shaft through the winding cylinder along an outer circumference surface of the winding cylinder at a specific interval and spaced apart from one another in a direction of the shaft.

A method of manufacturing a slotless resolver, comprising steps of:

• preparing a winding tool comprising a shaft, a winding cylinder having the shaft inserted into the winding cylinder and maintained on an outer circumference surface of the shaft at a specific interval, and a plurality of first slot pins and second slot pins detachably combined with the shaft through the winding cylinder along an outer circumference surface of the winding cylinder at a specific interval and spaced apart from one another in a direction of the shaft;
• forming winding patterns in the first slot pins and the second slot pins of the winding tool by winding input windings, sine output windings, and cosine output windings on an outer circumference surface of the winding cylinder;
• removing the first slot pins and the second slot pins by separating the first slot pins and the second slot pins from the shaft and the winding cylinder;
• and
• obtaining the winding patterns having a cylindrical shape by pulling and removing the winding cylinder from the winding patterns in the direction of the shaft.
