HP 300/40

The HP 300 series are 8 pole brushless direct-drive motors. Due to the high number of poles, the resistance could be reduced and the torque could be increased. Thus we were able to produce a motor with low weight, high torque and impressive power. The speed resistant S-version has a kevlar armoured rotor, which can withstand very high RPM. These motors can be used together with gearboxes or as power units for ducted fans and boats.
