In 2007, a new market
brushless outrunner motors combined with a
high end planet gear.
In the past, this
area was reserved for the brushless
inrunners due to the required high rpm’s, which
outrunners couldn’t achieve, mostly limited by the controllers.
In the meantime, modern brushless controllers are able to drive outrunners at more than 30000rpm and therefore allow this new combination. Again, the outrunners beat the inrunners in many applications – especially when big props need to be driven at higher voltages. The result is a multiplication of the max. power throughput by factor 3 to 4 at the same motor size. Props which had been too large for a direct drive application with outrunners can now be handled at very low motor weight and high efficiency with this combination.
- Power throughput upto 2000Watts at efficiencies between 80 und 90%
- very low motor / system weight and slim outer shape (good for small fuselages)
- Usage of very big props for a very high efficiency of the whole system
As a reaction, Torcman decided to offer the TM350-20 (and TM350-12) as a special edition, combined with one of the best and established planet gears on the market, the Reisenauer Superchief. The Superchief is a very robust, low-noise and low maintenance gear which has proven it's quality over a long time period.
The well established TM350-Series has been completely redesigned for this application. The mechanical and electrical parts have been optimized especially for this gear - it can be directly mounted to the motor without additional flanges. Thermal conduction has been improved and convection is now supported by a cyclone shaped rotor back shield.
of applications is between 4 bis 12 Lipos
and props from 15 to 24
inches diameter at a power of 1200 to 2000Watts,
short time until 2500Watts (800 –
1400Watts for the TM350-12).
Examples and applications can be found on the webpage under "Fascination - Practical Samples".
