Product description and features
The Hacker A50-V4 motors are 14-pole external rotor motors whose efficiency has been further improved through continuous development. The A50-V4 series has a new rear end shield with a fan, which enables even more efficient internal cooling of the entire motor. The different lengths and windings enable precise adaptation to the model and allow a power range of up to 2000W.
