Brushless Outrunner Motors

Scorpion Power Systems specializes in the design, development and production of premium Brushless Outrunner Motors. Each part of a Scorpion Motors is designed from the ground up by experienced and passionate engineers with the best quality components available to provide power, efficiency, and reliability which is a grade above the rest!

Our motor magnets are custom manufactured from a select premium supplier to be able to withstand the high temperatures associated with high performance applications. The copper wire we use to wind the stators is covered in an imported enamel coating which is rated to 250+ degrees C (482 F), so it can take the heat and keep on performing. Our premium imported 0.2mm Stator sheets provide the highest torque per amp ratios, and best top end performance capabilities. Our imported bearings are of the best quality providing long lasting and reliable run time operation. For everything else, we utilize aviation grade 7075 aluminum and other materials that are CNC machined in-house and anodized for a fit and finish that is second to none.

With a motor and service of this caliber, you would expect to pay an ultra-premium price, but with our efficient manufacturing procedures and streamlined distribution chain, Scorpion motors retail for very affordable prices making them one of the best overall values on the market today. Combine that with our fast production times, customization options, and fantastic customer support, the value of choosing Scorpion Power System will be worth it everytime.
