Abstract
There is provided an electrical motor in which the dimensional accuracy of a stator is increased more easily, and the influence exerted on a magnetic circuit is kept as little as possible. In an electrical motor in which the statorformed with n number (n is a positive integer) of teethin a row in a straight line form is bent into an annular shape and the end parts thereof are connected to each other, the sum of opening angles θ of a cutoutformed between segments of the statoris made larger than 360 degrees, and a minute clearance is formed between the opposed surfaces of the cutoutwhen the stator is bent into an annular shape.
