Teledyne LeCroy’s MDA8000 series of motor-drive analyzers performs three-phase power-analyzer static (steady-state) calculations, dynamic three-phase power and mechanical motor analysis, and ...

Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

As we've discussed in the last two Code Calculations articles, when calculating the total load on your system, you must first identify specific types of loads. Then, you can calculate each load. For ...

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it’s ...

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is The flux-oriented control (FOC) is a commonly used ...
