This is the Scorpion V2 Series HK-2221-6 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!
