With a long history of building some of the best performing ESCs on the market, HobbyWing enters the miniquad motor market with this new 2205 line. Thanks to Drone Eclipse for sending it over.

Summary

Given the long history of quality and performance in the ESC market by HobbyWing, I was very curious to see what thier first motor would do. As with some of the other motors to hit the bench recently, this one is still the integrated prop shaft, square magnet, and multistrand windings.  That being said the quality of the build is absolutely stellar.  Tolerances are tight, the motor is extremely smooth, and the machining is excellent.  The design also includes active cooling elements in the top of the bell.  The magnets are quite thick and quite wide, and the air gap is quite tight, so square magnets should not really be a loss here.  The base of the motor is well designed with plenty of clearance around and over the screw holes.  The two things that impressed me the most about this motor were the quality of the machining and finish, and the smoothness.  Clearly this is a well built motor, and it manages to come in at 28g which, while a few grams heavier than some of the competition, is a few grams lighter than some of the others.

Now on to the bench results!

Test Results

The design choices mentioned above combined with the claim by HobbyWing of N54 magnets in this motor really piqued my curiousity. Some interesting things here. The KV test right below the 2300kv mark, and for a 2205 this motor showed quite excellent response times. It showed almost identical RPM performance to the Tornado T1 2205 2300kv motor, but slightly better response times, especially on the heavier props.  Thrust lagged behind the Cobra Champion a bit on the heavier props, but response times are quite a bit better.  Essentially the XRotor 2205 performs on par with some of the top performing 2205 motors from the current batch on the market. Very solid performance across the board, especially on the heavier props.  This is a very solid first entery from HobbyWing
