Getting beyond numerical results for testing electric and hybrid drive trains

摘要

Since significant efforts are now focused on more efficient electrical machines and drives, evaluating motor efficiency has become extremely important. The main issue, however, is how to implement an accelerated procedure that obtains the motor or drive efficiency for all operating points safely, accurately and rapidly. Ordinary test methods only offer inadequate numerical results. Here, HBAA discusses how to get beyond numerical results To get beyond numerical results, all electrical, mechanical and physical signals must be acquired simultaneously at high sample rates, coupled with advanced real-time custom analysis and fast data transfer to automation systems, making it possible to perform electric motor and drive efficiency mapping accurately and rapidly, as well as almost any type of advanced analysis.
