Pre-drive test of an implemented novel Radial-Gap Helical ROTLIN machine

摘要

The future trend of mechanical systems is to substitute most of them by Permanent Magnet (PM) and/or Electromagnetic based ones. This paper presents an extension research on Design, Modeling, Simulation and Implementation Based Control of a novel ROTLIN (Rotary-Linear) Radial Gap Helical Machine. This is an hybrid of Magnetic Screw with a Synchronous Motor by modifying the design concept. The implemented machine is comprised of Stator, Mid-Layer Rotor and Inner Layer Translator, and tested as a high thrust force actuator. In the pre-drive tests, the back-EMF was measured and a relative rotational speed derived; Encoder signals and Position tracking were confirmed as well. The PD controller combined with DOB was designed but could not alleviate all vibrations in position response. The Pre-Drive Tests were conducted and Open Loop V/f control was used for preliminary experiments, consequently the Rotary and and relative Linear motions were confirmed.
