Abstract
PURPOSE: To widen the limits of application to high-speed machines substantially by sampling commutator displacement signals with a period corresponding to a commutator rotating speed and by recording and indicating the result of such computation by the use of a suitable time scale.
CONSTITUTION: The continuous displacement signals of a commutator segment 1a from a position sensor 2 is sampled and A/D converted with a suitable period by the use of a position-specifying signal of rotational mark 1b from a mark detector 3 as a starting point in an A/D converter 4a. After stored in a memory circuit 4b, the output signal of said A/D converter 4a is processed by an arithmetic processing circuit 4c and outputted from an X-Y protter 4d by a suitable time scale. In this case, the displacement of each commutator segment 1a is distributed between its maximum and minimum values, and one rotation period of a commutator 1 in said X-Y protter 4d is the product of the total of commutator segments 1a and the time required for passing a pitch between commutator segments 1a.
