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 include 3% impedance as standard. Some Yaskawa VFD drives include a dual diode bridge rectifier which can […]
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 and light weight Ease of control Low maintenance Low cost In order to determine if DC variable speed drives have the […]
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 system runs an electric motor and a speed control unit. VFD drive technology in today’s […]
AC variable frequency drives are also known as VFDs, VSDs (variable speed drives), AFDs (adjustable speed drives), inverters, and micro drives. AC variable frequency drives are used in AC Servo Systems, Air Compressors, Conveyor Systems, Lathes, Mills, Plastic Extrusion, Slitter Lines, Food Processing, Waste Water Treatment Systems, Submersible Pumps, HVAC Fans and Blowers, and many […]
Over the past decade, energy saving VFD drives have allowed to become a cost efficient way to reduce power costs and increase system production efficiency. Approximately one third of the world’s electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. These fixed-speed applications don’t always require the full […]
Eaton VFD troubleshooting begins with technicians working with the VFD in production. Eaton VFD troubleshooting can be time consuming, so manufacturers tend to keep spare Eaton drives on hand for production lines that cannot afford downtime. When Eaton VFD troubleshooting cannot be resolved in the plant, technicians in the field are known to send their Eaton […]
HVAC VFD repair should be taken with extreme caution. HVAC VFD repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing HVAC VFD equipment. Many HVAC VFD controllers have an internal DC bus that […]
The practical requirements of a modern DC VFD are extremely diverse. A DC drive should be full of features and easy to use which sometimes, isn’t a simple task. The challenge is to find an innovative solution which excels in both, and the solution, is the ABB DCS800 VFD. The ABB DCS800 VFD offers a […]
When choosing VFD manufacturers for motor speed control equipment in production, it is recommended by Precision Electric to choose VFD manufacturers who offer extensive technical support for their products. Precision Electric recommends using VFD manufacturers in the United States, such as ABB or Lenze Americas. VFD manufacturers in the United States such as ABB and Lenze Americas have a […]
Eaton’s SVX9000 VFD (variable frequency drive) is the compact, modular solution to adjustable speed applications. The SVX9000 VFD enables a broad range of new application capabilities, and option cards allow the to configure the VFD to meet any requirement. With its wide voltage range, high overload ability, and user-friendly alphanumerical keypad, SVX9000 VFD Drives are the smart decision for every user. There are just three […]
Shipping a VFD (variable frequency drive) safely is important because electronic components can be easily damaged due to poor packaging. When shipping a VFD, the first step to safely package the VFD is to locate an appropriate size box for everything you intend to ship. When using larger boxes, keep in mind this will mean higher […]
Approximately one third of the world’s electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. This proves that significant energy efficiency improvement opportunities are available by applying variable speed drives to electric motors. Variable speed drives have over the past decade allowed to become a cost efficient way to […]
