Considerations on the Pole Pitch Length of a Linear Parametric Motor with an Open Magnetic Circuit

摘要

This paper describes the effect of the pole pitch length on the characteristics of a linear parametric motor with an open magnetic circuit. When the pole pitch length tau is 44 mm, the static thrust becomes maximum at C=148 mu F, with a maximum value of 14.1 N. The thrust-to-mass ratio of a motor with tau=44 mm is approximately 1.7 times higher than that of a motor with tau=70 mm.
