2025. The first second-generation test prototype goes to our sales team. After trying it, they are blunt: not enough of an improvement.
That prototype changed the body structure to a split housing, so a repair replaces only the damaged part. But we do not freeze the design there: the second prototype changes the inside of the tool.
The motor comes first. We fit a high power-density brushless motor: pure copper windings, N45SH high-temperature magnets, FOC vector control. The gears are now 20CrMnTi alloy steel, carburised and hardened, in an aluminium-alloy gearbox housing; the bearings and cells are upgraded too.
With this version we also set ourselves a rule: motor ratings are never overstated. What the rating plate says is what you get.
For stores and users this rule saves trouble: you can sell by the rating plate and work by the rating plate, and no inflated number will catch you out.
