The best way of covering many of the above mentioned topics is efficiency mapping and dyno testing or dynamometer testing.Everybody wants to increase the efficiency of their systems.Having the raw data is important for this,because if something goes wrong you can reference previous tests and also perform in depth analysis in a post processing program such asnCode GlyphWorksor MATLAB.Furthermore,this is of the utmost importance fordynamic testing,because when carrying outdynamic loading or testing drive cycles,if you don’t have the raw data,you can get some weird inaccurate efficiencies。
When they start testing they will have a set DC bus voltage,followed by a set speed。
They will then load the machine with a certain torque.You will do this for all of the desired torques and speeds available in the range of the machine。This will then give you the efficiencies for all desired set points,and you obtain an efficiency map.These points will be taken at a specific temperature range.Sometimes you have to wait for the machine to cool down in order to take a measurement at a set point.This is whereHBM’s eDrive测试系统can save a lot of time for customers because taking test points in a number of cycles rather than a number of seconds will have the machine spending less time heating up。
Often,people will test the limits of the machine,and basically blow them up;or attempt to.They will push to achieve the maximum speed to know the mechanical limits of their machine.The ability to trigger and have a buffer of data will allow researchers to understand not only where themachine failed failed。
