If you are someone who is trying to decide between a variable frequency drive and a basic soft starters for motors, then look no further. We will explain everything you need to know and hopefully, make your decision a little bit easier. As we all know motors require a lot of energy when they need to accelerate quickly to their maximum speed and both of these technologies can both be used to reduce the inrush of currents as well as limit torque. These properties do wonders in protecting your equipment as well as reduce heating. There are a few things to consider when trying to choose between the two and these include the application, system requirements and the cost.

Let’s start with basic soft starters for motors. They protect your motors from influxes of power and limit this rush. They give your motor that gentle ramp so it can achieve full speed without the damage. They are initially used at startup and can also be used in the stopping process. Some of the applications where you can use basic soft starters for motors would include anything where speed and torque control would be required; to reduce large startup rush of currents; if the mechanical system needs a gentle start; and if any pumps are used to eliminate pressure surges where fluid changes directions.

So what are the benefits of using a soft starter? Well, they are an economical choice when it comes to reducing inrushes; they are a great choice when you require speed and torque control. They are also compact which is great if you need more space as they take up less space than frequency drives.

Now let’s go over variable frequency drives and what they can do for you. They protect and control speeds in AC induction motors. They are also applied and the start and stop time and work throughout. You might have also heard them being referred to as adjustable frequency drives, they are the same thing. Variable frequency drives are mainly used in applications that require complete control over speed, where saving energy is the main concern, and when you also might need some kind of custom control.

Some of the benefits you will receive from using a variable frequency drive include a lot of energy savings; it has fully adjustable speeds; you can control the starting, stopping, and acceleration; it gives you a smooth motion; and it is versatile. Keeping in mind, it is a lot larger than a soft starter so if you have limited space, this probably isn’t your best choice.

Now that you know what they both are and how they can both benefit you, you will feel more confident in picking the right one for your workplace and business. Choosing the right one should be based on the needs of your industry and the needs of your specific application. You can easily find these both available online where you can find the perfect model for your industry.
