B40 Competition Inner Rotor Electric Motors

Product Description and Features

The completely new external housing design features milled cooling grooves that provide optimal heat dissipation while maintaining consistently low weight. In addition, an internal fan delivers highly effective cooling. Operating noise is reduced to a minimum thanks to asymmetrically positioned air outlet holes.

This proven design is already successfully used in the Hacker C50 Competition series. The front and rear bearing shields are screw-mounted. A new segmented high-performance rotor made from optimized magnet material delivers exceptionally high efficiency. The B40 Competition is equipped with larger ball bearings than the standard Hacker B40.

This significantly reduces friction and extends service life. Furthermore, the larger 5 mm diameter shaft prevents vibrations even at extreme rotational speeds. In the geared motor variants, the shaft comes with an integrated pinion already fitted. The increased power output of the B40 Competition motors is supported by a robust gearbox with a 6 mm output shaft.
