Talk:Magnetic gear

Acceptance rationale
I view there being no likelihood of improvement in the Draft: namespace, and see a potential of greater than 60% for surviving a deletion discussion, so I have accepted it. It requires a massive clean up. Fiddle  Faddle  13:48, 7 April 2015 (UTC)

Possible errors
While reading up on second order magnetic gears, I noticed that the example table and the following bit of text seem to contradict each other.

“Since the number of pole pairs is twice the number of magnets, there must be an even number of magnets on both rotors.”

In the table, the number of magnets is 20 for the low speed gear and 14 for the high speed gear, but the pole pairs for these gears are listed as 10 and 7. Ten is half of 20, not twice 20.

Also, the example graphic doesn’t match either rotation mode listed in the table. The number of stator pieces (26) doesn’t seem to fit with either rotation in same direction or counter rotation of the drive gear for 32/8 poles on the low and high speed gears.

If the chart is right, the wording is wrong, or if the wording is right then the chart is wrong.

This is very confusing to those unfamiliar with magnetic gears and one or the other need to be corrected, or clarified. 50.229.82.74 (talk) 17:21, 24 March 2022 (UTC)

Cycloidal vs planetary drives ratio
I believe the following is wrong:

'there are "cycloidal drive" gears with a gear ratio similar to planetary drives, also called "epicyclic" or "eccentric" gears.'

Planetary gears are not eccentric gears.

Cycloidal drive ratios are not similar to planetary gears. A cycloidal drive will rotate the output shaft by a single gear 'tooth' for every revolution of the input shaft, completely different to planetary gears.

Eccentric gears are more comparable, but still completely different.
