VFD manufacturers’ installation recommendations aside, how much voltage can a motor’s winding insulation really tolerate? The winding insulation system on existing general purpose motors may generally withstand pulses of 1000 V, which is totally inadequate for IGBT drives on 480 V systems. If the ac input voltage to the VFD is 240 V or less, the dc bus voltage is kept low and the magnitude of these “reflected waves” generally is not an issue.
Single phase to three phase VFDs are used to replace three phase service when only single phase is available. But VFDs can do lots more than just get you three-phase. There are cases where you will need three phase input to a VFD but these are super advanced and I will not get into these here.
The only problem is the small VFDs are only rated for about 3 HP, but check the amp draw on the motor, you might be able to squeak by on the amp rating, and it would also give you a lot more speed control. You might want to look at the insulation rating on the motor. Also, with heavy use, it needs to be an F rated insulation on the windings. The rating will be on the data plate.
Variable frequency drive (VFD) systems make use of a motor, operator interface and drive controller assembly. Motors used in VFD systems are normally three-phase induction styles. Single phase motors or synchronous may be used.

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.

I recently was doing some energy savings projections that involved looking at what would happen if I added a Variable Frequency Drive (VFD) to a pump serving a hot water system. In the course of doing that, I got to wondering if there had been improvements in VFD efficiency that I should take into account since the last time I researched drive efficiency.
Variable frequency drive - VFDs can be used to control the speed of a machine. There can be significant energy reduction if the machine is slowed down when it does not need to operate at full speed. For example, pumps operated so that they run at a speed dependent on the flow requirements will reduce the cavitation losses in the pump. If the pump is required to run at constant full speed, the addition of a VFD will actually waste another 5% of energy.
