This is the Scorpion V2
Series HK-2221-12 V2 brushless motor. Improvements include better cooling with
the integrated centrifugal blower fan, higher efficiency with a new stator
design and a new threaded-on flux ring for more solid
construction.
Scorpion HK Series Brushless Motors are built from the best
materials available, and are designed to provide both quality and performance at
an affordable price. Scorpion starts with high quality aluminum alloy parts that
are produced on the latest CNC milling machines. These parts are then gold
anodized to provide a beautiful, long-lasting finish. The stators are made with
0.2mm laminations to give maximum efficiency, and minimum Eddy current losses.
The stators are epoxy coated to prevent shorts, and are wound with wire that is
rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are N-50EH
style, which are rated for operation at 200 degrees C (392 F), making a motor
that is virtually impossible to burn up in normal use.
All Scorpion HK
Series 22mm motors come with 3.5mm male Bullet style connectors already
attached, and include a hardware package that contains 3 matching female Bullet
connectors for your speed controller and a cross style backplate mount with 4
screws. Since the HK series motors are primarily designed for Helicopter and
Ducted Fan use, they do not include a prop adapter. If you intend on running a
prop on this motor, you will need to purchase a prop adapter for a 3.175mm shaft
(1/8 inch).
Scorpion Motors are built to last, and are backed with a
2-Year warranty against defects in materials or workmanship. For the best
overall combination of quality, performance, and value, give Scorpion Motors a
try!
