BRUSHLESS EVO3 #1717T delta w Graupner 97237

BRUSHLESS EVO3 #1717T delta w Graupner 97237 With the introduction of the new BRUSHLESS EVO 3 motors GM-Racing has succeeded in developing highly efficient motors which set new standards in terms of reliability and performance.

- Multiple extra-thick windings together with an extremely low-loss design and sintered neodymium magnets ensure enormous power and high efficiency.
- A thicker shaft provides for better true-running ofthe magnets.
- Cooling slots and an integral cooling fan keep the motors at reasonable temperatures even under the harshest competition conditions. The result is that the GM-Racing BRUSHLESS EVO 3 motors achieve constant levels of performance and efficiency which can only be reached briefly by brushed motors due to friction of the carbon brushes and subsequent overheating.
-BRUSHLESS EVO 3 motors feature sensors and a sensor connector, and can therefore beoperated in conjunction with GM-GENIUS speed controllers with or without sensors; it is possible to remove the sensor leads for even greater reliability. Numerous successes by our team drivers, also in sensorless mode, such as the A-Final victory in the first A-Final (run in the rain) by Marc Fisher, demonstrate how controllable these motors are when used with GM-GENIUS controllers even under difficult conditions.
- Variable sensor timing.
-High-performance ballraces for safe operation at high rotational speeds.
- The motors satisfy the DMC regulations, EFRA rules and the ROAR regulations (as of April 2007).
- Special extra-powerful plastic-bonded upgrade magnets are available as accessories: for competitions in which plastic-bonded neodymium magnets are prescribed or in which a different performance characteristic is desired, the upgrade magnets, Order No.97215.1, are fitted as a substitute for the original magnets. These upgrade magnets are a special development for GM-Racing, and are around 30% more powerful than bonded military spec. neodymium types; they fit both the BRUSHLESS EVO 3 and the BRUSHLESS EVO 2 motor. Rotational speed with these magnets is around 10 - 15% higher than with standard sintered neodymium magnets, combined with reduced current drain and slightly higher maximum efficiency. For thisreason these magnets are also a particularly good choice for slippery surfaces and 1 : 12 model cars.
