Problems it solves
Why this model gets specified
Panel space is the constraint on small machines. BR100 delivers the same power output in a volume reduced by 30% compared with peers.
Dust and contaminants reach the electronics through the cooling path. A completely independent air duct with no vent holes on the upper chamber side and top keeps pollutants out of the component area.
Commissioning time eats margin. More than 80% of the control performance is available without motor learning.
Who it is for: OEMs building small water pumps, engraving machines, fans and conveyors who need a compact 0.75–11 kW drive.
