Conventional planetary gears are used for heavy industrial applications, such as in the main engines of airplanes and power shovels. This gear system can be used for accelerators by installing an outring gear in the case of exchanging input and output. But a magnetic planetary gear can be used as an accelerator while driving the outring gear. This paper presents a performance characteristics test for magnetic planetary and differential gears for accelerators. It is shown that the gear ratio of such accelerators is larger than that of ordinary accelerators. The reason for this is that an outring gear is driven differently from a planetary gear. We deduce the best conditions for driving planetary and differential gears. For example, the sun gear speed Na of the output is 1050 rpm when the planetary gear speed Nb of the input is 50 rpm and the differential outring gear speed Nc is 200 rpm. Magnetic planetary and differential gears can be used for wind power generators and industrial clutches.
