Abstract (en)
[origin: US7861340B2] A treatment bed has two lifting motors connected in parallel mechanically in the height-adjustable lifter. In order to load the lifting motors evenly and avoid torsions in the lifter, a balancing circuit that measures the supply currents of the lifting motors is provided. If a difference is determined, then the respective current is briefly interrupted several times until the magnitudes of the currents approach one another.
