Proper Installation and Maintenance Practices for Variable F
Proper Installation and Maintenance Practices for Variable Frequency Drives (2020) - The use of a variable frequency drive (VFD) to control the speed of an AC induction motor has numerous benefits, including energy savings, improved reliability, reduced equipment wear and tear, and more precise control of motor speed.
When operating, VFDs generate heat, and the output voltage waveform is not a true, clean sinewave. These characteristics present challenges when installing a VFD. However, following a few proper installation practices can help ensure successful operation. Most VFDs fail because of an improper installation and not because of a poor-quality product.
The following seven recommended practices will help ensure a successful VFD installation and optimal equipment life.
