Correct name for a specific design of electric machine
Correct name for a specific design of electric machine
(OP)
Hi,
I thought this might be a good place to ask a question about a specific design of electric machine.
Trying to search online for information is difficult if you don't know the right terminology. For example, I could not easily search for information on matrix converters until I knew they were called matrix converters...
The design I am interested in would consist of a stator or stators with both an internal and external rotor. Therefore having two shafts. Mechanical power transmission can then be done between the two shafts at differing speeds & torques, modulated electrically.
This is similar to a coupled generator-motor arrangement but more compact.
Does this arrangement exist and if so what would it be called so I can do some more research?
Thanks, Ian

Hysteresis clutch?
Magnetic particle clutch?

The airplane engine community has tried for that for about 90 years, and have succeeded only once. (Tu Bear contra-rotating props work fairly well. The rest have failed to perform reliably.)

This is the successor company to the company that introduced them in the 1930's.
