An unrivaled level of efficiency with an improvement of approx. 4% compared to the B50 motor could be achieved with many innovative detailed solutions in design, technology and quality.

During the development phase, numerous innovations were introduced and successfully implemented on various components of the motor concept.
This includes the segmented high-performance rotors made from optimized magnetic material. The outer housing design with milled cooling grooves offers perfect heat dissipation with the lowest weight. The integrated high-performance fan cools the B50 competition engines in the most effective way. The running noise is also reduced to a minimum with asymmetrically mounted air outlet holes.

The B50-Competition is equipped with larger ball bearings than the Hacker B50. This significantly reduces friction and optimizes service life. In addition, a larger shaft with a diameter of 6mm prevents vibrations at extreme speeds. The front and rear end shields are screwed together. In the case of the geared motor variants, the shaft is already equipped with an integrated pinion. The increased power output of the B50 Competition motors is ensured by a high-performance gearbox with a 6mm shaft.
