Just for completeness, I was searching for BLDC, and found the Sieg
Super X3 uses a 1HP BLDC motor. But if you look at the schematics / part
list, they show it as being a 230V motor. Hmm, wonder if they boosted
the AC with a multiplier, then rectified it (PWM?).
look up "astro flight" in california. They make some pretty serious cobalt
magnet motors, brushed and brushless.
There's another US maker of high performance motors on the east coast, the
name slips my mind, but they clearly sell motors and gearboxes for RC
Wow. Astro 3220 Brushless Motor 4kW to 6kW
Windings are available for operation from 24 volts DC to 144 Volts DC
8 turns 96 volts 47 amps 750 in oz 7,500 rpm 5.6 Hp 90%
Assuming you're looking for something moderately priced and don't need
a low inertia, high performance motor, look at MCG and the Panasonic A
Bodine and Oriental Motor have a few choices as well, but I don't
believe anything as large as what you're looking for.
Do you need an encoder, or just the commutation feedback?
BLDC motors are essentially 3-phase permanent magnet synchronous
motors. The most common drive scheme uses Hall sensors in the motor to
tell the drive the relative position between the motor's windings and
rotor. The drive responds appropriately to run the motor at the
Minas As top out at 400W/100V, they do have a 750W/200V though...
Erk, they don't really ID the AC vs DC motors too well. They do have
some 590W 80vdc rated motors...

Baldor has some nice ones up to 3HP, but probably not cheap.
You know you need a special drive for them, right (not a regular SCR
drive intended for DC motors). The commutation is done externally and

Thanks to everyone that helped me get over the man-thing of
over-built... I don't see any brushless DC surplus, and their retail
price for 1HP is about the same as brushed DC.
I can't see a markedly superior performance of BLDC to PMDC.
