Hacker B50-8S Competition with Planetary Gearbox 6.7:1 Needle Bearing, # 10100901

The Hacker R&D department has achieved a small quantum leap in the development of the new B50 Competition motors. A previously unsurpassed high efficiency with an improvement of approx. 4% compared to the B50 motor was realized 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. These include the segmented high-performance rotors made of optimized magnetic material. The outer housing design with milled cooling grooves provides perfect heat dissipation with minimal weight. The integrated high-performance fan additionally cools the B50 Competition motors in the most effective way. The operating noise is also reduced to a minimum with asymmetrically positioned 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 stronger shaft with a 6mm diameter prevents vibrations at extreme speeds.

The front and rear end bells are bolted. In the geared motor versions, 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 output shaft and needle-bearing planetary gears.
