How Variable Frequency Drives Enhance Factory Production

Those who are working in a factory or industrial automation industry must be aware about variable frequency drives, usually called VFDs. Variable frequency drives are known for best speed control and highly useful for operational facilities. Here, CM Industry Supply Automation – VFD & Servo Drive/Servo Motor expert mention some ways that VFDs can enhance complete factory production and efficiency.

1. Less Disturbances to the Power Supply Line

When utilizing an AC motor, the early start-up puts an enormous strain on the whole power supply line. This is not applicable with a Variable Frequency Drive as the voltage begins at zero and slowly rise up from there.

Fundamentally, rather than starting with a high bang like with an AC motor, a Variable Frequency Drive slowly and progressively picks up pace to simplify the strain on the power supply line. The difference is obvious, particularly among minor equipment like computers, which can drop offline when an AC motor begins up.

2. Good Adjustments

While a Variable Frequency Drive begins at a low speed, it can be adjusted more comfortable even from a distant location. It became possible with Programmable controllers that permit operators to remotely start the Variable Frequency Drive at a lower speed while picking up in power over time. For controller’s programmable applications are very helpful for adhering factory parameters.

Adjusting torque within time become easier too. Also variable frequency drive can be set to a particular torque limit for preventing excess currents and overloading. This gives protection against overuse, allowing factories to maintain their machines and stop fast wear and tear.

3. Control of Acceleration and Deceleration

The variable frequency drive offers good control over acceleration and deceleration to the operators. While comparing with an AC motor that starts up and utilizes tons of power and energy, a Variable Frequency Drive can begin at a controlled speed and gradually accelerate from there.

This conserves the motor’s strength and efficiency and save money in the long run. As for slowing and stopping, the ability of controlling this process with a Variable Frequency Drive means that mechanical stress cut down and the longevity of machine increases.

4. Cost efficient and energy saver

VFD offer maximum energy savings. The variable torque loads cut down complete energy usage and the lower the beginning speeds. As compare to AC motor which just operate at full speed, a Variable Frequency Drive is adjustable, cut down energy consumption and lower complete costs for factory operators.

VFD offer monetary saving and could reduce the requirement for costly components such as vanes and dampers in the factories. The ability of adjusting the acceleration and stopping VFD speed can also cut down the requirement for gearboxes that can cut down on space.

Sometime, an energy provider may provide particular incentives to industrial customers who utilizes variable frequency drives. All things considered, there could be huge financial gain for those who choose Variable Frequency Drive rather than an AC motor.


Remember that there are many VFD makes and models available on the market such as Lenze VFDKEB VFDSiemens VFDYaskawa VFDDanfoss VFD and more therefore there could be noteworthy differences in the complete quality and dependability of the drives.

Monetary savings cannot be the only factor to choose a variable frequency drive but can be a possible benefit. Hope now you feel more informed about Variable Frequency Drives advantages and how they can enhance your factory automation and processes.
