PURPOSE:To easily verify the computation result of numerical values and the result of operation of a generated force by comparing mutual forces of a motor which are found respectively on the side of a magnet and on the side of a coil in their combination. CONSTITUTION:Elements are assembled, individual conditions such as the intensity of the magnetization of a magnet, the magnitude of a current and the like are set, numerical values are computed, and the density distribution of a magnetic flux or the like is computed. The found density of the magnetic flux inside a magnet and a coil is multiplied by the current of the coil and by the magnetization of the magnet, and individual energies are computed. In addition, since conditions are different according to the kind of an electromagnet which is to be found, the individual conditions are changed, and the relative position of the assembled element is changed. After that, the density distribution of the magnetic flux is computed by calculating the numerical values, and the individual energies are then computed. Then, the difference between the energies which have been found in the first stage and the second stage is divided by a relatively moved distance, and a generated force is found. This operation is repeated a plurality of times by changing the conditions or the like as required. The operation result is verified by comparing the mutual forces of a motor which have been found respectively on the side of the coil and on the side of the magnet. That is to say, their coincidence is confirmed by referring to its accuracy. When they do not coincide, the cause is analyzed, and the operation is repeated. |
