Question

No motion has she now, no force identify figure of speech

Answer 1

may be the figure of speech is inversion

Answer 2

Irony. In the poem, the speaker describes his beloved as possessing 'no motion or force' and that she is 'revolving with the Earth around the Sun'.

It basically means that she is actually dead and the speaker cannot be with her.

The speaker's beloved was connected to nature deeply while the speaker was not.

Hence, there is a mismatch here in what is being said and what is being meant. That is why, it is an example of Irony.
