Prototype Design and Performance Characteristics of a Multispeed, Single-plane Magnetic Gear for Practical Application

摘要

We have investigated various prototype magneticgears in which the pinion and gear are separated by maintaininga gap. Such gears have the merit of eliminating contact, and theydo not need lubrication, both of which virtues are unobtainablewith ordinary gears. The present study of magnetic gears isintended to establish operating principles for gears usingpermanent magnets or electromagnets.In this report, I present the prototype development andperformance characteristics of a multispeed, single-planemagnetic gear suitable for practical use.Results show that it is reasonable to enlarge the intersectingzone of contact area in the case of kinematic motion or toenlarge the main contact zone for heavy load carrying.
