Features of RWP Models

These models add a belt-type stepless speed changer to an RWM hollow-shaft geared motor. They are about 30% lighter and 20% smaller than our previous belt-type stepless speed changer (0.4-kW model).They can also operate at high torque while at low speeds (compared to the 0.4-kW model), not a traditional strength of inverters.
