In a brushless motor, the magnets are one of the most important components. The 2 key parameters for motor magnets are the magnetic strength and the maximum temperature rating. Most magnets that are commonly used in brushless motors are either with a temperature rating of between 80 to 100 degrees Celsius, which is between 176 to 212 Fahrenheit.

The magnets used in Scorpion motors are the finest available, with temperature rating of 200 degrees Celsius, or 392 degrees Fahrenheit! This allows them to operate in the most demanding conditions without the worries of having them demagnetize due to overheating.

These are the same magnets that are used in the construction of the Scorpion HK-4025 series motors, and supplied with the Scorpion HK-4025 motor kits. The magnets are simply the best magnets available for motor construction.

These magnets are sold as replacements for Scorpion Motors or kits, or for motor scratch-builders that want to have the best magnets that are currently available. Since these magnets have a curved profile, they are manufactured in 2 varieties: one with the North Pole on the inner surface, and the other with the South pole on the inner surface. Because of this, the magnets are sold in matched pairs with one North and one South pole magnet per pair. The magnet with the North Pole on the inside is designated with a red stripe on the ends.
