The present disclosure teaches a system for co-planar arrangement of multiple power absorption units for vehicle testing, which is generally used as a dynamometer. The system may include a plurality of power absorption units for example, two or three eddy current brakes co-planarly arranged and connected to a shaft via a pulley-and-belt system. The shaft may connect to an axle hub of a vehicle, directly or indirectly. In one embodiment, the shaft may connect to the axle hub via a universal joint coupler and a hub adapter. In some embodiments, each of the eddy current brakes may include a rotor, a plurality of coils surrounding the rotor, and a plurality of brackets attached to the coils. A load cell may be attached to one of the brackets to measure a torque or force. One or more bearings may be attached to the eddy current brakes or the shaft.
