Spur-Gear-System Efficiency at Part and Full Load [PDF]

open access: yes
A simple method for predicting the part- and full-load power loss of a steel spur gearset of arbitrary geometry supported by ball bearings is described. The analysis algebraically accounts for losses due to gear sliding, rolling traction, and windage in ...

A non‐intrusive method for friction and windage losses estimation in induction motors

open access: yesIET Electric Power Applications, Volume 18, Issue 10, Page 1347-1358, October 2024.
A new technique is proposed to estimate the windage and friction losses in induction motors. This method is completely non‐intrusive and only requires the nameplate data. Abstract In the in‐service induction motors (IMs), friction and windage losses (FWL) value should be determined non‐intrusively. Hence, in the in‐service IMs, instead of measuring FWL,
