Hello -
We've had a few discussions regarding brushed vs brushless motors. The most important point I remember was that brushed and brushless ran at similar energy efficiencies under load. I'm wondering about efficiency with respect to size and weight. Let's compare this brushless motor http://www3.towerhobbies.com/cgi-bin/wti0001p? <http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLWY0&P=7> &I=LXLWY0&P=7 to this brushed motor http://www.andymark.com/CIM-motor-FIRST-p/am-0255.htm Both are in the 300 watt range. At 12v, the unloaded brushless motor, rotates at 32k rpm and the brushed motor at 5.3k rpm. Of course, the brushless motor would need a lot more gearing to make it usable in a tank. That aside, could I expect roughly the same performance from both motors ? It's hard for to believe that because the brushless motor is 1/14 of the brushed motor weight and 1/7 of the volume. Is there another factor (besides cost) I need to take into account when comparing a brushed to a brushless motor ? Thanks, Doug -- -- You are currently subscribed to the "R/C Tank Combat" group.
