What pump for Continuously Variable Transmission (CVT) oil?
Good morning everybody. In the project I am working in we are planning to use a CVT transmission (it is not automotive). We need to pump its special oil through a cooler and throw it back to the contacting surfaces in order for reject the heat generated durting its operation. But, as this type...- laranjatomate

Sync/Async generator efficiency
Thinking better, I have found efficiencies in the 94-95% range for high efficiency asynchronous motors, while the async generators have shown up to 92% in the few catalogs I have found. That means some kW of difference. I found a catalog of Metalcorte (former Eberle) with open circuit and...- laranjatomate

Sync/Async generator efficiency
Right. That rough efficiency estimate is enough for my thermal load calculations. I have found few efficiency data and now I can deal with both generator and motor efficiency. Thanks. Dad, are there cakes, pies and panettones in Brazil? Pay attention, son: if there are not such things, we will...- laranjatomate

Sync/Async generator efficiency
Good morning everybody. I am responsible for evaluating heat loads inside the nacelle of a small wind turbine (100kW). That´s difficult to find catalogs which describe the mechanical efficiency for generators. These data are almostly available just for motors, either synchronous and...- laranjatomate
