释义 | > as lemmasdynamo-electric machine The full name dynamo-electric machine was given by Siemens in 1867, to distinguish his invention from the magneto-electric machines previously used, in which the electric current was generated by means of a permanent magnet.

Thompson early in 1882), the use of the word has been extended so as to include all forms of these machines: see quot. 18842.extracted from dynamon.dynamo-electric machine dynamo-eˈlectric adj.
