How Variable Frequency Drives Improve Efficiency And Productivity ?

The use of Variable Frequency Drives (VFDs) is on the rise, as more businesses realize their benefits. In our previous blog post, we discussed how VFDs can reduce energy costs and improve productivity. In this article, we’ll take things one step further by delving into the inner workings of a Best VFD Australia—how it works and why it improves motor efficiency.

Reducing motor energy losses

A variable frequency drive is a device that changes the speed of an electric motor in response to signals from its controller. This allows you to operate at lower speeds for longer periods of time, which can lead to significant reductions in energy consumption.

A variable frequency drive works by adjusting the voltage applied to a motor’s stator windings so that they rotate at a precise speed–typically between 30 and 100 Hz (60 Hz being standard). This makes it possible for you to reduce your operating costs by reducing:

  • Motor energy losses – By lowering motor speed, you reduce heat generation within the machine as well as wear on moving parts such as bearings and gears. This results in less maintenance costs over time while also improving efficiency levels overall;
  • Power factor correction – When using more efficient motors with VFDs installed on site, there will be less demand placed upon utility companies’ grids due because less electricity is wasted through resistance within those systems;

Improving motor utilization

One of the most important benefits of VFDs is that they can reduce motor start-up time. When a motor starts, it takes some time for it to reach its rated speed and power output. This period of low efficiency is known as “stretching” and occurs when motors are first switched on or after an extended period of downtime.

The length of this stretching period depends on how much load there is on the drive system, but generally speaking you want it to be as short as possible so that energy consumption is reduced during those periods when your equipment isn’t producing any useful work (i.e., when it’s just sitting around).

Reducing magnetic saturation

Magnetic saturation is a problem that occurs when a motor is working hard and cannot produce any more torque. This can happen if the Motor is being used for long periods of time, or if it’s operating at higher speeds than normal.

Magnetic saturation can cause serious damage to your equipment, so you need to be aware of this issue and take steps to prevent it from happening.


VFD Australia  are one of the most effective tools you can use to improve the efficiency and productivity of your motorized equipment. By using this technology, you can reduce energy losses, improve motor utilization and reduce magnetic saturation in your machines. This means that you’ll be able to run them longer without having to replace parts or repair damage caused by overuse because they were not properly maintained in the first place!
