Consideration on the improvement of performance characteristics and application of the linear parametric motor

This paper describes the relationship between pole pitch length of the stator core and characteristic values of the linear parametric motor with open magnetic circuit. We made five motors of the different pole pitch length that there were the stator core width W = 34 mm constant. This time, static thrust and characteristic values of each motor were discussed. In addition, using the motor of pole pitch length 50 mm, the automatic door model was produced experimentally, and the velocity characteristic was examined.
