Strict cascade power balance
Cascade Drive Efficiency
Combine one to five stage efficiencies from the same operating point. Calculate efficiency alone, output power from input power, or required input power from required output.
Cascade result
The identities follow directly from η=Pout/Pin for each consecutive stage with no unmodelled branch between boundaries.
The US Department of Energy’s Motor-Driven Systems guidebook shows that motor efficiency varies with load. Its motor and drive sourcebook advises using manufacturer drive efficiency as a function of operating speed or load. Therefore this calculator requires actual same-condition inputs instead of component-type defaults.
Removed claims: the former tool prefilled motor, gear, belt, chain, worm and coupling efficiencies and a typical-value table without traceable operating points. It also silently ignored blank, zero or >100% stages while still showing a total. All active stages are now mandatory and validated.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
