Force Characteristic Analysis of Airflow Type Linear Pulse Motor by Permeance method |
| Abstract |
Linear pulse motor (LPM) be suitable a field where smooth linear motion of high precision is required, because it"s structured with minute teeth pitch in airgap of between and stator and mover(forcer). Force and position of LPM are effected sensitively by the teeth pitch, air gap, permanent magnet and excitation current. So, LPM is much important to analyze the force characteristics. This paper was applied to permeance mothed for force calculation at airgap. The airgap of LPM is maintained from the pressure generated by an air-bearing. Simplified airflow and permeance methods will be used to calculate the air gap under static conditions. Therefore, the maximum available force is then derived using the coenergy method with variable air gap, also normal force and linear thrust was acquired from variable minute displacement 1[㎜]. |
