Description
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.
