Filed: 1994-10-27
Abstract: PURPOSE: To reduce the stepping angle of a moving body by impressing drive frequency signals which excite waves having specific numbers of nodes in the circumferential direction upon electrode patterns provided at every specific number and, at the same time, impressing drive signals which are successively switched upon the electrode patterns. CONSTITUTION: Electrode patterns 301 are arranged at 24 deg. intervals and all of the numbers shown in the figure are connected to each other with the same number. The patterns 301 can shift standing waves which are excited by a vibrating body by five steps and, at the same time, excite excite vibration mode. The wavelength of the excite vibration mode corresponds to 60 deg. and node sections are positioned at every 30 deg. which corresponds to a half wavelength. Therefore, when the ratio of the number of phase changing times (p) to the wave number (n) is set at p:n=5:6, the stepping number of the moving body per one rotation becomes 5×2×6=60. Therefore, the stepping angle of the moving body per one rotation can be set at 6 deg.. Consequently, the stepping angle of the moving body can be made smaller.
