Abstract: PROBLEM TO BE SOLVED: To provide a slotless motor which can combine two or more unit coil bodies easily and correctly.
SOLUTION: Two unit coil bodies facing each other are combined in a circular form with different inner diameters to constitute two or more circular coil bodies. Each circular coil body with a smaller inner diameter is inserted inside the circular coil body with a larger inner diameter sequentially out of two or more circular coil bodies to constitute a stator coil. Then, the respective sums of horizontal widths of two or more unit coil bodies of U phase, V phase and W phase are made equal, so the intensities of magnetic fields of the U phase, V phase and W phase are balanced and the stator can be manufactured correctly in response to the designer's intent, and the assembly process can also be simplified significantly.
