CHARACTERISTIC ANALYSIS OF AN ARC TYPE LINEAR PULSE MOTOR

아크형 직선 펄스전동기의 특성해석

In this paper, the characteristics of an arc-type linear pulse motor(ALPM) with permanent magnet are analysed using analytical and 2-D finite element method. To verify the analysing method. An ALPM which can be used as actuators of servo systems is designed and constructed. The stator of the ALPM has a permanent magnet and 4 pole exciters in order to provide a detent and thrust force. It's rotor radius is 70 mm and average torque of 60 $N{\cdot}cm$. The test results of the prototype ALPM have reasonably good agreement with those of analytic solutions.
