Robust resistor

A new hybrid farm vehicle uses 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 to a maximum power of 80kW

A new hybrid farm vehicle uses 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 to a maximum power of 80kW to allow remote working.

Braking is a mix of conventional friction brakes and regenerative braking. An REO water-cooled braking resistor handles emergency conditions. REO ensured that the resistor was able to dissipate the required electrical power in all conditions and that it is robust enough to be mounted on a vehicle.
