There's obviously no way to be sure without having one to actually test, but I'm doubtful. It might be able to handle 150A continuously for a few seconds, or maybe even half a minute, but I personally can't see that being a genuine continuous rating. 150A is a LOT of current; you'd need at least 8-gauge motor wires to actually handle that (120A is about the limit for 10-gauge). I'd say the 150A is likely to be a short-term rating, but I could be wrong. No way to know until it's tested.
Northy; most people using sensorless setups right now are using either Neu, Medusa or Feigao motors. Neu are the creme-de-la-creme of brushless motors, being really efficient, but also quite expensive (you can also buy Tekno-Neu motors, which are specifically designed for car use):
http://www.neumotors.com/2008/Root/Site/Welcome.html They're around the $250 mark for a "1515" class motor, which are suited for truggies and monsters. The "1512" class motors are good for buggies, and more more like $220. Not good for us brits.
Then there are the Medusa "Afterburner V2" motors, which are excellent:
http://www.medusaproducts.com/motors/036-V2.htm They come in various can lengths (and of course, winds) and are almost as efficient as Neu motors, but considerably cheaper. A 60mm Medusa motor is equivalent to a Neu 1512 in terms of power, but comes in at around $130. Not bad.
Then there are the Feigao motors, which you should stay away from. They're cheap, but very inefficient and poorly made. If they don't overheat on you, the rotor will separate or the can will fall apart, lol.
Castle will be bringing out their own motors very soon, though, which are based on the Neu design. They'll be just as efficient and well made, but built tougher with larger bearings and a stronger can. They'll have 1515 and 1512-sized motors coming out, and should be around $150. I'm picking one up myself lol.
Basically, there's a wide price range of motors out there...it just depends how much you can spent. A bit of efficiency goes a long way.
Sorry for the essay...I get a bit carried away with this stuff!

From Slovakia? I'd never have thought he wasn't English, by the quality of his text.
