Product overview
The Scorpion HK5-3220-955kv is a BLDC motor intended primarily for the SAB RAW 420C helicopter, developed around guidelines supplied directly by SAB Factory. Its stator measures 32 mm in diameter and 20 mm in thickness, with 12 stator arms and 10 stator poles. The electrical construction uses a 5+6 Turn Delta winding and 1.05mm motor wire, with a motor Kv of 955KV RPM/Volt. An internal fan and an external centrifugal fan provide airflow through the motor for cooling.
Installation space must accommodate a 40.95mm x 45.98mm motor body and a 4.98mm x 22mm external shaft; motor weight is 189g. Continuous ratings are 65 Amps and 1500 Watts, while the 90A and 2000 Watts peak ratings each apply for two seconds. The specified LiPo cell count is 6s; higher counts require appropriate gear ratio adjustment. The package contains one motor, three female 4mm connectors, three heat-shrink pieces and one hardware/accessory pack. Weight including packaging is 210.6g.
