Inrunner B40-9S Competition + 6,7:1 Kv 4690

Product description and features

A completely new outer casing design with milled cooling channels allows perfect heat dissipation at very low weight. In addition, an internal fan improves cooling. The asymmetric air outlet reduces the level of noise to a minimum. We are already using this design on the C50 competition very successfully.

The front and rear bearing plate is attached with screws. A very high degree of efficiency is achieved by a new, segmented high-performance rotor from optimized magnetic material. The B40 competition comes with larger bearings as the regular Hacker B40. This significantly reduces friction and improves the lifetime. In addition, a larger sized shaft with a diameter of 5mm prevents vibrations at extreme speeds.

On gearbox motor versions, the shaft is already equipped with an integrated pinion. The increased power output of the B40 competition motors is obtained by a strong gearbox with 6mm shaft.
