When the armature is held to prevent rotation, the bridge is balanced by means of resistors in the other arms so that no voltage appears across the output. When the armature then rotates the voltage across the bridge output is the back EMF produced by the rotation of the armature. A variable reference voltage obtained from the same D.C. power source is introduced opposing the back EMF and the resultant is used to control the current between the power supply and the bridge. The armature back EMF is thereby held by the bridge balance essentially equal to the reference voltage and if a heavy load is applied to the armature shaft the resultant bridge unbalance will retain the desired armature rotational speed constant irrespective of load changes, but variable directly with the applied reference voltage.,下面是Steam reforming catalysts for hydrocarbons and process for preparing the same* and steam reforming process for hydrocarbons专利的具体信息内容。
