Magnetization Fixture Design of Magnetic Gear Using Soft Magnetic 3D Printing

Abstract

Gear transmission system has been widely used in industry for its mechanical gears possessing the characteristics of low cost and large torque transmission However the industry's requirements on the precision and maintenance of the transmission system are increasing day by day This research investigated the integrated magnetic ring that could be magnetized had the characteristics of polar anisotropy and skewed magnetic poles and manufac-tured based on soft magnetic 3D printing technology A new configurated sample of a skewed magnetization fixture is formed by 3D printing which is featured with low magnetizing energy consumption Under the condition of the same number of magnet-izing current turns after magnetizing the magnetic flux density of the new configur-ated magnetization fixture was 53% higher than that of the traditional silicon steel sheet one Then the magnetized magnetic ring was applied to the concentric magnetic gear to achieve a design that could reduce the torque by 36% and finally the proposed design was further verified with experimental results
