A duty cycle or power cycle is the fraction of one period in which a signal or system is active. Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. As a formula, a duty cycle (%) may be expressed as: Equally, a duty cycle (ratio) may be expressed as: where is the duty cycle, is the pulse width (pulse active time), and is the total period of the signal. … WebDec 5, 2024 · Conclusion. AGMA and ISO gear ratings can be executed with load spectra (duty cycles)—based on Miner’s rule—as explained in ISO 6336-6 (Ref. 1). Load spectra may be defined by different methods. In this paper, the ability to generate a duty cycle from a time series (time-torque-speed data) is explained.
