<p>The submarine drive motor (1) has a pole wheel (4) and at least 2 signal sources (10,11,12,12') for detecting its rotation angle and/or revs and supplying corresponding signal information to a drive motor regulation device (7). The signal sources are arranged at spaced positions relative to one another, so that at least one of the signal sources remains functioning upon occurrence of localized interference.</p> |
