Variable Frequency Drive (VFD) Repair & Services
Why Use Variable Frequency Drive (VFD) From the last several years, Variable frequency drives (VFD) is becoming the demanding preference for many industrial processes that need to make use of motors with changing speeds. VFD is one kind of motor a controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. There are different names for a VFD such as variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, Microdrive, and inverter.Reasons to use VFD : It helps to Red...

How to Build a Variable Frequency Drive for a Three-Phase Motor?
The VFD or the Variable Frequency Drive can control the speed of the 3-phase motor. The VFD can increase the efficiency and performance of the motor and provide for energy bill cost reduction. The drive, when applied and installed, reduces the jerks that occur when the motor is started. VFD panels provide easy control of the drive.Built of the VFDThe VFD controls the AC or alternating current rotational speed, as it can control the frequency at which electric power is supplied to the motor. The 3 basic components of the VFD are the rectifier, DC bus, and inverter.The electric current tha...

Advertising on a budget -- Part 3: Frequency, frequency, frequency
This is the third article of a three-part series. I'm illustrating the marketing challenges of, a small business. If you don't remember anything else about marketing, remember this: Frequency is king.The more often you can get your name in front of your potential and current customers, the more likely you will make a sale.Depending on what study you look at, people need to see your message anywhere from three to 27 times before they act upon it.And, if you want to brand your business, then you need to get it in front of your customers as often as possible.How do ...

VFD Variable Speed Frequency Inverter
In variable frequency speed regulation system, slow down and stop of the motor are achieved by gradually reduce the frequ

How does Variable Frequency Drive Work? Its Uses
Using VFDs have a number of economic benefits despite the fact that they generate a large number of heat and harmonics. It has 3 main components – the input section, which regulates the flow of AC into the system, the Rectifier converts the AC c to DC and the Inverter section will convert the DC back into controllable.Benefits of VFDsAs mentioned in the previous paragraph, using VFDs has numerous economic benefits. The primary reason why VFDs are preferred is because of the speed control which the devices offer. This was machines can be sped up or slowed down easily. The accelerati...

Open Loop Variable Vector AC Frequency Drive
SD300 series open-loop various vector AC frequency drive is a high-performance generic vector frequency drive,it is a new generation technology upgrading products in SINOVO. The AC frequency drive with the new characteristic appearance design and use the unique way of control to achieve a high-torque

Close Loop Vector Variable Speed Frequency Inverter
Closed-loop vector control uses a vector algorithm to determine output voltage, similar to the open-loop control. The difference of the key is that closed-loop vector uses an encoder. Encoder feedback, paired with the vector control, means 100% of the motor’s rated torque is available at 0 rpm.

Radio Frequency Identification - Industry to Witness Huge Growth 2023
Radio Frequency Identification Global Market- OverviewRadio frequency identification, or RFID, is an advanced technology that comprises small tags which in purposes is to transfer the signals. This RFID devices are extensively used in retail sector which are used as remote scanners to detect the RFID tags deployed on individual products, allowing them to register a variety of information, including quantities of inventories and trace the product in various location. Considering, the technical aspects the RFID are categorized based on low frequency which transmit the signals 30KHz to 500KHz, ...

high-frequency inverter rectifying part increase rectifier
 When consumers buying high heeled Tank, they frequently face the option between frequency inverter and high-frequency inverter. For the purposes of inverter producers, clearly, they believed to be their own good. Supplying frequency inverter manufacturers state high-frequency inverter reliability and stability; large frequency inverter manufacturers state high-frequency inverter to conserve space, comparatively low price. In reality, the frequency and high-frequency inverter ultimately is better, it's hard to generalize, and also we could say benefits and pitfalls. Users should fully u...
