FAILURE DETERMINATION DEVICE, DRIVE CONTROL DEVICE, AND FAILURE DETERMINATION METHOD - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18044822 Titled 'FAILURE DETERMINATION DEVICE, DRIVE CONTROL DEVICE, AND FAILURE DETERMINATION METHOD'
Simplified Explanation
The abstract describes a device that is used to determine if there is any failure in a rotating body. The device includes a rate generator that produces a sensor signal with a frequency that changes based on the rotational speed of the shaft. A frequency calculator then calculates the frequency of the sensor signal. Finally, a determiner analyzes the calculated frequency to determine if there is any failure in the rotating body.
Original Abstract Submitted
A failure determination device determines whether any failure occurs in a rotating body including a shaft rotatable by received power and a support mechanism supporting the shaft rotatably. In detail, the failure determination device includes a rate generator, a frequency calculator, and a determiner. The rate generator outputs a sensor signal of which a frequency varies depending on a rotational speed of the shaft. The frequency calculator calculates a frequency of the sensor signal. The determiner determines whether any failure occurs in the rotating body from the frequency calculated by the frequency calculator.
