| 摘要 |
<p>The following invention refers to an apparatus for powering at least one electric motor (4, 6). The apparatus (100, 101) comprises at least one driving device (3, 5) of the electric motor (4, 6), a power circuit path (7) positioned between a generator (2) of power voltage (VCV) and the at least one driving device (3, 5), first means (8) inserted in the power circuit path (7) for enabling and preventing the powering of the at least one driving device (3, 5), a control device (10) powered by the feeding voltage (VCV) and suitable for controlling at least the first means (8). The apparatus (100, 101) comprises a protection device against the overvoltages (50, 60) comprising second means (COMP1, Q1) suitable for detecting a current that flows in the power circuit path (7) from the at least one driving device (3, 5) to the generator (2) of power voltage (VCV) and third means (Q2, OPAMP1) suitable ford absorbing the current detected (Iclamp). <IMAGE></p> |
