The DHB series dyno absorbed energy is converted into heat in two rotors which are located
external of the coils.
The rotors are designed with curvilinear cooling fins for fast heat dissipation into the
atmosphere.
This design provides the smallest physical size for air cooled eddy-current design dyno.
Simple construction and desirable speed-torque characteristics are adaptables to most
applications.

● High Stability
● Short Response Time
● Wide Power Range
● Long Service Life ; Easy To Service
● Good Heat Transfer
