It's "Dr. _paralyzed_" actually. Not like with a PhD, but Doctor like in Dr. Pepper.
If it is a Himax motor, then it's dimensions best fit the 500 watt models:
HA3618 Brushless
500 Watts
• Designed as direct replacement for 500/550 type can motors - same diameter & mounting pattern,
• Direct replacement for B50S and Aveox 36/15 type motors,
HA3618 -This 500 watt motor is for midsize models weighing 48-62 oz for 3-D flight, up to 80 oz for aerobatic flight and up to 100 oz for leisurely flight.
HA3618-2300
HA3618-3000
HA3618-4500
That looks like one of the Model Motors MiniAC brushless motors, they have the blue anodized end caps, and carbon fibre casings. The only thig is that the MiniAC motors only come in the "300" sized versions, which are a fair bit smaller in diameter than the one you have there....
