薄形サーフェイスモータの試作  [in Japanese] Trial Manufacture of a Thin Surface Motor  [in Japanese]

One of the features of linear motors is that they can be driven directly with linear motion. This paper proposes a meal assistance apparatus which can be easily operated by hospital patients. This apparatus uses the scoop operation to the patients in order to assist the operation. This is driven by a direct-current surface motor (DSM). In this paper, we focus on three aspects of the DSM: (1) a 21-mm thin DSM was manufactured experimentally; (2) magnetic characteristics and magnetic circuit were calculated by the FEM, and it was designed in the most suitable way; and (3) the maximum static thrusts of the DSM in the x-direction and y-direction were 19.5N and 50.3N, respectively.
