When the winding of the coil is θ = 60 °, the force (torque) generated at this time is reduced by about 13.4% as compared with the case where θ = 90 °. Then, unless the angle θ is 90 °, the force generated is smaller than that in the case of θ = 90 °, and thus the efficiency of the magnetic flux always decreases.

In addition, there is a problem that the manufacturing cost increases due to an increase in the number of manufacturing processes, the productivity decreases, and the unit price of the product increases, which lowers the economic efficiency.
