What Is A Variable Frequency Drive
What is a variable frequency drive? Variable frequency drives are also known as variable speed drives, VFD's, adjustable speed drives, and inverters.
Variable frequency drives are solid state motor control systems designed to control the…

Yaskawa VFD Drives
Yaskawa VFD drives are designed to minimize harmful demand for input harmonic distortion. Yaskawa VFD drives up to 25 HP are available with optional 3% or 5% equivalent line impedance DC Bus Reactors. At 30 HP and above, Yaskawa VFD drives…

DC Variable Speed Drives
The first electric motors were designed and built for operation from direct current power. The following should be considered when choosing DC variable speed drives for production:
Wide speed range
Good speed regulation
Compact size…

Types Of VFD Drives
There are 3 general types of VFD drives:
Eddy Current VFD Drives
DC (Direct Current) VFD Drives
AC (Alternating Current) VFD Drives
Each of these types of VFD drives can be divided into different variations. Every type of VFD drive…
