摘要:
A rotor core has installation portions in which first magnets, which are permanent magnets, are arranged. The installation portions are larger than the first magnets. The first magnets are divided into a first group and a second group. The first magnets in the first group are fixed to the installation portions to be offset in the positive rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles. The permanent magnets in the second group are fixed to the installation portions to be offset in the inverse rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles.

A digital data producing system includes a keyboard, a mouse, a data saving memory for saving sets of produced digital data, an additional character string memory for storing at least two sets of additional character strings, and a data file name assigning section for assigning to the sets of produced digital data a data file names produced by selecting one set of additional character strings from among the at least two sets of additional character strings stored in the additional character string memory in accordance with instructions input using the mouse when a naming rule is selected and serially adding members of the thus selected set of additional character strings to a basic data file name. According to the thus constituted digital data producing system, it is possible to simply assign to sets of digital data correlated with each other file names composed of, for example, a common character string plus additional character strings to clarify the correlation between (among) the sets of digital data.
