Abstract: Provided is a method for making a double-walled yoke that allows an inner yoke (4) and outer yoke (3) to be integrally joined to each other both easily and securely. Such a yoke provides an adequate cross sectional area for a magnetic path of the yoke while minimizing the weight of the yoke. A tubular member (14) destined to be form the inner yoke and a cup-shaped member (13) destined to form the outer yoke are both fitted on a punch (7) and a drawing process is executed by using an appropriate drawing die (8). The outer yoke may have a small wall thickness as long as it is capable of retaining its shape during use or supporting a bearing for the motor. The inner yoke is required to be relatively small in size as long it is capable of forming a satisfactory magnetic path for the motor. A satisfactory magnetic path can be obtained if the yoke is provided with an adequate wall thickness so as to provide an adequate cross sectional area for the magnetic path.
