Reducing cogging, transient torque, torque ripple

Measuring torque is essential for different kind of tests and applications. Especially in electric-machine testing, it is important to understand the effiency and dynamics. However, torque is not a static value: therefore, measuring torque with a high accuracy is crucial. A high-bandwidth torque measurement is also needed to understand what happens instantaneously. This could be: cogging torque for a steady state operation, torque response during loading Torque during control changes. But what happens exactly during the measurement and how can cogging torque, torque ripple and other characteristics be measured and reduced?

What is a Power Analyzer?

A power analyzer is used to measure the flow of power (w) in an electrical system. This refers to the rate of electrical transferral between a power source and a sink, hence the alternative expression of power as energy per second (J/s). Measuring power flow is a critical yet rudimentary process that can be carried out with consummate ease using a standard power analyzer. More advanced systems acquire electrical signals and carry out integrated calculations for additional, complex analysis.

Case Study: How to Future Proof Your Test Systems for Hyb

The concept of the automobile has evolved rapidly over the past decade. Sales of hybrid and pure electric cars have risen continuously, in parallel with an increasingly widespread use of electric motors in the automotive industry, both combined with conventional internal combustion engines and as stand-alone solutions. To keep up with such fast-paced evolution in technology, there must be an equally rapid progress and development in the analytical methodology used. A growing priority in automotive industry is now to not only optimise the individual components of the drivetrain, but to create more integrated systems of the components themselves.
