RaserTech, brushless power from induction...

[zeropointbug]

Hey guys, check this out. RaserTech, a new motor licensing company, has a new type of AC induction motor that has PM brushless power density and efficiency, without PM (permanent magnets).

They have a 500hp AC motor that weights 147 lbs. Apparently, it uses magnetic resonance; I think i read that it pulses the motor and the motor self resonates at it's own frequency and creates a pure sine wave.

Anyways, this would mean really cheap electric motors for RC...

The power density allows 1500 watt motor for RC, and would weight 270 grams. They thing about this is that they would be alot cheaper, and more reliable. The controllers would be alot cheaper (simpler) also. The motor tech is rated 92% peak efficiency, 89% full load; the controller is 98% efficient also.

Just thought i'd show you another neat technology.
