Analysis of high-speed rotary wireless power transmitters

Abstract

This article provides a review and study of the possible types of rotating wireless transmitter (RWT) constructions. The object of the study is the high-speed transmitters with a rotation speed of the order of 10 000 revolutions per minute and more. They are mainly used in number of innovative technologies for machining details of sophisticated shape and hardness. The paper examines the influence of centrifugal forces, speed, acceleration, mass and dimensions on the RWT. In order to clarify the advantages of the types of constructions, computer simulations were made using the software product Ansoft Maxwell, showing the distribution of the magnetic field and its intensity at the individual points of the RWT. This article revises four main types of the RWT constructions, along with the design methodology, mechanical and electromagnetic analysis.
