The $29.99 motor is 110VDC, not 260V so his reduction is much less.

also, the $9 motor does not have roller bearings.

Neither do the $19 or $21 motors.

So, the $9 motor is the 260 volt one, without roller bearings.

the $29 has roller bearings and is listed at 110 volts.

Also, the $9.99 motor is not speciffically listed as having dual
shafts although it does come up on the search for cual shafts.

$9.99 p/n 10-2167
$19.99 and $21 p/n 10-1783
$29.99 p/n 10-1573

Also, you are correct that the numbers don't add up.

the $9.99 motor is listed as a 2-1/4hp at 260 volts @ 5 amps
260 times 5 = 1,300 watts
1,300 / 748 = 1.73 hp

I'm kinda confused myself, but this seems like what we are talking
about.
