Gemfan 2206 2300kv

Tested KV:2170kv
Stator W:22mm
Stator H:6mm
Last year Gemfan offered a series of motors based on the RCINPower GT line, which were some very solid performers.  With the changes in motor market recently Gemfan has reworked their line with a new manufacturer and an upgraded stator size. These 2206 motors are excellent build quality.  The machining is beautiful and the tolerances are very tight.  This motor uses multistrand wire in the windings, thick arc magnets, and a very tight air gap. The motor has a fairly unique shaft design with a 3mm steel shaft that goes from the bottom all the way through the center of an aluminum prop adapter that is machined as part of the bell. The steel insert is actually visible at the top of the prop shaft.  Given the 3mm shaft I was a bit surprised when I put this motor on the scale.  For a 2206 motor it's very heavy, coming in at almost 34g with 45mm of wire. That puts it into a weight class with 2207 and 2306 size motors, which is going to be a tough sell. Overall though, the motor is very well made, and beautifully designed.


Probably the most interesting thing here is that the KV tested significantly lower than the stated KV, coming in at just under 2200kv.  The results here reflect that, with good efficiency, but at the expense of top end due to the lower KV.  On heavy 5" and light 6" props, that basically puts it on par with the top performing 2205 2300kv motors but with improved response times and slightly improved efficiency.  That also means that this motor can be loaded up quite heavily without a downside, pushing even midrange 6" props without much trouble at all.  Given the weight of the motor, that probably puts the ideal application in the 6" range.
