The Use of Computational Fluid Dynamics in the Thermal Design of Rotating Electrical Machines

open access: yesActa Polytechnica, 2000
Thermal constraints impose limitations on the power capability of many electric motors and generators. However, inadequate data on ventilation air flows and convection heat transfer coefficients hamper the design process.

Calculation of oil volume and simulation of oil injection lubrication for high-speed helical gears based on image recognition technology

open access: yesJixie chuandong
ObjectiveAt present, there is a relatively sufficient analysis of oil injection lubrication for spur gears, but there is limited research on the commonly used helical gear oil injection lubrication for high-speed gears, especially in calculating the wind
