VFD

A variable frequency drive can serve many purposes in the operation of a business or industrial concern. It works with solid-state electronics and depends entirely on the components of the VFD.

The most common vfd is a voltage-source inverter, which converts the line input from AC to an AC inverter. Let’s examine some applications and why a VFD might fit your business well.

VFD Applications

Used primarily in manufacturing with rotating equipment, they are designed to eliminate amperage spikes when large motors are engaged for production. When selecting a VFD, finding the correct one for the process you intend to use it for is essential.

The VFD is installed to reduce the wear the motors experience, and having a VFD can extend the life of the motors it regulates through acceleration and deceleration. It is controlling the motors to work only when needed benefits a business here.

A fixed-speed pump, compressor, or fan creates over one-third of all electric power. The equipment seldom, if ever, works at maximum output. Installing a vfd can reduce power consumption by almost 50 percent, and that can represent a significant saving. Performance enhancement and tech development have led to reduced costs of VFDs leading to excellent efficiency of operation and lesser expenses for the unit itself.

Regulating Electrical Use

The VFD is constructed with circuitry to take a 60-hertz power line and convert it into current to supply power. Creating pulsing voltage, the current runs intermittently at the desired rate of speed.

Pairing your new vfd with motors that match the system will reduce power consumption for variable torque loads. Pumps, fans and blowers will see reduced energy use on a declining scale. You can reduce electrical usage by 40 percent, and more significant savings are created with every 10 percent reduction in motor speed.
