VFDS Manufacturer is a leader among variable frequency drive suppliers.
A variable frequency drive controls alternating current torque and motor speed in electro-mechanical drive systems. In layman’s terms, it is an adjustable speed drive that regulates the frequency and voltage to the motor. You can find variable frequency drives, or VFDs, in everything from small appliances to giant compressors.
VFDS Manufacturer is a leader among variable frequency drive suppliers. Our company concentrates on VFD design and VFD manufacture. VFDS Manufacturer is china VFDS Company located in Los angeles. Our main focus is creating the highest quality products. The main products single phase to three phase VFD, three Phases to three Phase VFD and so on.
For industrial purpose the power is to be delivered for larger distance hence AC power supply is required to drive the motors. The rectifier in a VFD is used to convert incoming ac power into direct current(dc) power. There are 3 pair of rectifier combination is used for converting 3 phase AC into DC Normally 6,12 or 18 diodes will be used to serve this purpose. Rectifiers can be built using diodes, silicon controlled rectifiers(SCR), or transistors to rectify power. After the power flows through the rectifiers it is stored on a dc bus. The dc bus contains capacitors to accept power from the rectifier and stores it and finally delivers that power through the inverter section.
Installing variable frequency drives (VFD) are one of the easiest ways to save a significant amount of the energy required to run fans and pumps. Most fan and pump devices are very inefficient when running at part-load conditions, so installing a VFD drastically reduces the energy consumed during those part-load periods. Over the typical life cycle, a VFD greatly reduces the total cost of operation.

VFDs typically run on single phase power and convert it to three phase power to the motor. Three phase is preferred for speed control as it is easier to implement and maintains near 100% torque at low speeds Bottom line. Buy a VFD, connect it to a 3 phase motor, plug it into 120 or 240 single phase outlet and you are good to go. BTW, I have a couple of Rob's units, one for my KMG and another for the 9 inch disk grinder. They are top quality and easy to set up and if you do have a problem Rob is always there to help.
All VFD applications require programming. You have to make it do what you want. Parameters like minimum and maximum frequencies, number of motor poles, maximum current, overload response, braking behavior, acceleration profiles, etc. must be set by the user to match your installation's needs. The voltage/frequency curve is user configurable too, which is very useful for your kind of application where you are operating outside the normal frequency range of the motor. Good VFDs come with a display that can be set to show the motor speed (or any number of other parameters). If I were doing this, I would use a 1HP 208V two-pole motor and a 1HP VFD with a 240V input.
One feature that is present in the Mitsubishi VFD and not present in cheaper units that I have installed is a braking resistor. These are used in applications where you want to use the motor as a brake to stop the machine or control the speed of a descending load. The bigger the resistor, the quicker the stop can be programmed in. You can eliminate coasting, even under significant load, when using a resistor. A unit without this resistor built in is quite a bit smaller in size and less expensive. Often an external resistor can be added to the cheaper units if you decide you want to add one later, but at least you aren't paying for it when you don't need it.
The variable frequency drive is becoming popular in setting up 3phase powered equipment. Most of the units are capable of producing variable frequency 3 phase power from a single phase source. The downside being there is a reduction of power rating. In other words, you would need a 5HP VFD to run a 3HP motor if the input is single phase. Now the beauty of using a VFD inverter is your ability to control motor speed. You can crank the cycles down so that the motor is barely turning. Or if you needed more speed, that is possible as well. Maybe even to the point of speeds that are dangerous. For instance, running a 60hertz motor at 400hertz.
