Product overview
The SkyRC X2205E Motor, product code SK-400021, combines a 2400KV motor and electronic speed controller in one propulsion assembly. Its integrated architecture saves installation space and simplifies soldering and wiring. The assembly weighs 38g, measures 34mm long and 28mm in diameter, and uses a 3mm shaft. Four mounting holes provide frame attachment points. Its construction includes 14 rotor poles, a stator specification of 12, NMB bearings and 0.2mm silicon steel laminations, with balance calibration for concentricity.
The integrated controller has Oneshot and damping light enabled, and a twisted signal cable reduces signal cross-talk. The assembly supports 2-3S LiPo batteries, with no-load current specified as 0.9A at 12V and resistance as 0.065Ω. Its electrical ratings include differing burst-current figures: 25A for the ESC and 20A (MAX) in the motor specifications. At 100% throttle, the performance figures are 20.4A current, 244.8W power, 2.64G/W efficiency and 17486RPM speed; additional figures cover 25%, 50% and 75% throttle.
