Development of Tubular Linear Permanent Magnet Synchronous Motor Used in Oil-well Field
Abstract: The tubular linear
permanent magnet synchronous motor (TLPMSM) is developed to constitute a new
oil-well pump system named as linear motor-driven one replacing the normal beam
balanced pump system mainly in order to eliminate the damageable steel pole.
Its structure is determined based on the real drive demand and the
corresponding analysis results are given. At last a small prototyped TLPMSM
with stator outer diameter of 140mm, effective stator length of 864mm is
designed and manufactured to verify the theoretical analysis and investigate
the performance, and make preparation for the large practicable prototype in
the future.
