With the new BRUSHLESS Dr. SPEED motors GM-Racing has succeeded in developing highly efficient motors which set new standards in terms of reliability and power.
Multiple extra-thick windings together with extremely low-loss construction and sintered neodymium magnets for enormous power and high efficiency A thicker shaft ensures more accurate true-running of the magnets Cooling openingsmaintain favourable motor temperatures even under ultra-harsh competition conditions BRUSHLESS Dr. SPEED motors feature sensors and a sensor connector, and can therefore be operated with GM-Genius speed controllers with and without sensors. This means that the annoying sensor leads can be eliminated for even higher reliability Variable sensor timing High-performance ballraces for high revuluttions The motors comply with DMC rules and EFRA rules.
