REO has a background in supplying drive peripheral components for use in arduous applications. One of the company’s recent projects has been to provide braking capacity for a newly developed hybrid farm vehicle.
The vehicle utilises 4 x 33kW motors to drive each wheel separately with active slip control on each. The unit also supplies connected equipment with a variety of AC or DC voltages up to a maximum power of 80 kW, to allow remote working.
As with most electrical and hybrid vehicles, the braking is a combination of conventional friction brakes and regenerative braking, with an REO water cooled braking resistor to handle emergency conditions.
For this project not only did REO ensure that the water cooled resistor was able to dissipate the required electrical power in all conditions, but that the mechanical construction of the resistor was robust enough to withstand being mounted on a moving vehicle.
