Operating temperature and speed SKF

2   Operating temperature is a function of the bearing load, size, speed and lubrication conditions. Lubrication conditions depend on the operating temperature, the viscosity of the lubricant and the speed. These interdependencies are dealt with by taking an iterative approach to the analysis, in order to achieve an optimum design for a bearing

Understanding motor temperature rise limits EASA

Tom Bishop, P.E. EASA Technical Support Specialist How do we know if a motor is operating within its temperature rating? The simple answer, and a good one, is that the National Electrical Manufacturers Association (NEMA) has defined temperature rise for electric motors in Motors and Generators, NEMA standard MG 1-1998. In this article we
