This is the upgraded version from the previous successful H2205 motor. SE2205 Motor uses Strong Magnets, Imported Copper Wire, High Quality Bearings and 7075 CNC Material.
It assembled with Imported NMB Bearing and Copper Wire to maintain the quality. The motor has been balanced by Motion Balancing Machine so you will see the colored balancing mud in the motor.
There are lots of brands who claimed their motors are balanced but in fact it is only static balanced (this means just to filter the highly imbalanced CNC out), its balancing quality is far away from real Dynamic Balancing. If you do not see the balancing mud inside almost all motors, that means their “balanced” word is inaccurate.
Dynamic balancing is the most time consuming part when manufacturing a motor so factories don’t like to balance the motors due to the longer production times to manufacturer and finish these motors.
