The Scorpion HK-45 series motor* is designed for
using on 700 class helicopters running on 12-cell Li-Po power. This
motor represents the most technologically advanced power source ever
offered for a 700 class electric helicopter and also produces 20% more
torque than the Scorpion popular HK4035 series motors and exceed 89%
efficiency.
Each of the new HK-4530-540KV Limited Edition motor is
wound with a single strand of 1.5mm wire for the highest possible
efficiency. This motor is capable of running continuously at an input
power of 4800 watts at 115 amps, and can handle peak inputs of 11000
watts and 250 amps for 2 seconds.
Scorpion Competition 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
Electro-Coated 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 custom manufactured to be able to withstand
high temperatures, making a motor that is virtually impossible to burn
up in normal use.
Scorpion Motors are built to last, and are
backed with a 2-Year warranty against defects in materials or
workmanship. However, due to the high RPM of these motors, and the fact
that we cannot control the installation and setup, the bearings are not
covered by the 2-Year warranty, nor is any subsequent damage caused to
the motor by a bearing failure. Bearings are a normal wear item, and as
such, need to be maintained and changed periodically. For maximum life,
make sure that a sufficient gap is left between the pinion and main gear
during motor installation to avoid binding, and put a small drop of oil
on each bearing every 5-6 flights. It is the responsibility of the
pilot to ensure that the bearings are maintained properly.
For the best overall combination of quality, performance, and value, use Scorpion Motors in your helicopter!
