摘要： In the field of stators including divided tooth-shaped iron cores and core back iron cores, a stator is provided in which the tooth-shaped iron cores and the core back iron cores can be easily connected to each other, and the tooth-shaped iron cores and the core back iron cores can be prevented from coming off in the radial direction. In the stator of the present invention, a yoke (24) is formed such that the circumferential width thereof is greater at a radial-outer region than at a radial-inner region, i.e., such that the distance (a) between yoke side faces (24A, 24A) gradually increases from a radial-inner region to a radial-outer region, and the distance (b) between two yoke side faces (24A, 24A) opposing each other and facing a space between the tooth-shaped iron cores (11, 11) that are disposed along a predetermined circumference with a predetermined interval is set to be a predetermined value over a range from a radial-inner region to a radial-outer region, or alternatively, is set so as to slightly decrease from a radial-inner region to a radial-outer region. A stator (10) is formed by inserting each of the core back iron cores (12) into a space between the tooth-shaped iron cores (11, 11) adjacent to each other. The present invention also provides a stator in which a packing factor can be increased and the magnetic flux can be made smooth, and a manufacturing method therefor.

摘要： A control command value map is formed with a voltage applied to a motor and an output torque as an output command value from a driver being taken on axes of coordinates, so that an output command value suitable for a power source voltage is easily and rapidly provided regardless of a variation in voltage of a motor driving power source by applying an output command value determined from the control command value map from an output command value determining means to a driving means. The motor can be driven based on such output command value.
