B40 Competition inrunner electric motors
Product description and features
A completely new, external housing design with milled cooling grooves offers ideal heat dissipation with a consistently low weight. In addition, an internal fan ensures good cooling in the most effective way. The running noise is minimised by the asymmetrically positioned air outlet holes.
This design has already been used successfully in the Hacker C50 Competition series. The front and rear end shields are bolted together. Very high efficiency is achieved with a new, segmented high-performance rotor made from optimised magnetic material. The B40-Competition is equipped with larger ball bearings than the normal Hacker B40.
This significantly reduces friction and improves service life. In addition, a larger shaft with a diameter of five millimetres prevents vibrations at extreme speeds. In the geared motor variants, the shaft is already equipped with an integrated pinion. The increased power output of the B40 Competition motors is ensured by a strong gearbox with a six millimetre output shaft.
