Considerations about motor noise level This post provides few considerations about motor noise level with respect to inverter supply. Noise might be considered as one performance criteria of the motor. Noise level of electric equipment is regulated by standards and regulations, often involving local law. Depending on the maximum level, Read more…
How are the motor load points defined? Customer is often interested in defining the performance (e.g. losses and efficiency) of a motor drive for specific operating points. But how are the motor load points defined? Over the years working with variable speed inverter fed motors I come across this topic. Read more…
Long motor cables Today we gonna talk about long motor cables and their impact on drive systems. In some projects the physical distance between VFD and motor as well as cable routing cause motor cables to be fairly long. This fact has impact on system design. The motor control might Read more…
