Liquid control resistance for electric motor - uses electrolyte circulated between electrodes by turbine and governed by flow-restricting slide

摘要

The resistance has an electrolyte ina container (10) and two electrodes (31A,B) - one connected to a supply and the other connected to the device being controlled, e.g. an electromotor. A diver circulates the electrolyte. A channel-like circulation space is bounded by a lower electrode (31B) between an input end opposite a supply column (31C) and an output end provided with a blocking slide (31D) of adjustable height. The driver is a turbine that can pump the electrolyte into a distrubtor (14) to which the supply columns of the electrodes are connected. A flap (21) sets the electrolyte's flow rate and is located on the suction side of the turbine. A device (54) controls the position of the slide (31D).
