Rotary UPS edits?
[edit]Your edits to the UPS article have been removed, though not by me. Please explain how a motor-generator system does not use kinetic energy to provide backup power. When the supply motor turns off due to loss of supply power, the generator keeps turning for a while because of... what?
A synchronous motor is also a synchronous generator. They are basically the same device and the only difference is how the field is excited, with generators usually self-excited or with permanent magnets, but motors can use that too. A synchronous motor instantly becomes a generator if supply power is lost, as long as some method of field excitation is still possible.

The definition of a rotary UPS is: it produces power using a "Rotating" machine (synchronous motor) to produce power. The motor / generator can be supplied with power by any number of devices, including batteries, or kinetic energy. How this power is supplied does not define what a Rotary UPS is, as the article describes. The article is fundamentally flawed and incorrect.
One company produces a rotary UPS which depends on a kinetic rotary device. I can only assume a representative of that company has written the section of the rotary UPS.
