Traditionally, it is implemented by several motors with complex transmission mechanism, which ...
A motor current calculation device (9) comprises a GND wire (94), a current detecting unit (95), a decision unit (96a), and a calculation unit (96b). A motor current (Im) that has been passed through a second fan motor (81) and a drive current (Id) that has been passed through...
Figure 11: Design a LabVIEW front panel to display waveform data and power calculation results. At this point in the measurement system, waveform data from the modules is used to calculate any power quality parameter desired. Some of these calculations are fairly simple while others are complex ...
PROBLEM TO BE SOLVED: To provide a motor-driven power steering control device capable of canceling an offset current generated by the switching of a driving method of a booster circuit for boosting a DC power voltage, and preventing the motor from being malfunctioned in switching the driving meth...
Before a fault current calculation can be performed, all of the possible sources of current must be identified. This can include some sources of current that may not have been considered. There are four possible sources of short-circuit fault current: On-site electric generators: These are close...
