When you’re looking to control your electric motors, you have three main options: speed controllers, variable frequency drives and variable speed drives. Each has its own advantages and disadvantages, but most professionals agree that the variable speed drive offers the best results in the long run.
This article will detail everything you need to know about these drives and how they can help your business or home thrive.
Are VSDs right for you?
Before you make the decision to invest in a variable speed drive, there are some factors you will want to consider.
For example, if your business’s processes are not that sensitive, it might not be worth investing in an expensive VSD.
If your business is constantly changing what they do and how they do it, then a VSD may be right for you.
How Does a VSD Work?
A variable speed drive is a type of adjustable-speed electric motor controller which allows the user to adjust the speed of an AC induction motor. A VSD is a type of modern electric drive that regulates the voltage and frequency applied to an electric motor by varying the effective number of turns in the stator windings.
This, in turn, varies the magnetic field generated by the stator and rotor currents flowing through them. This alters torque output and rotational speed according to user demand.
When Do I Install My VSD?
Variable speed drives are used in conjunction with variable frequency drives. These two types of technologies work together in order to create a precise and efficient system for your pump. In order for the VSD and VFD to work together, the VFD must be installed before the VSD can be placed on the system.
The timing is important because if you install the VSD first, it will have no way of communicating with the rest of the system because there’s no power going through it.
What is the Maintenance on VSDs?
Variable speed drives, or VSDs, are used in many industrial processes in order to better control the speed of a machine. There are many different types of variable speed drives available, so it is important that you know what type you need for your application.
The most common types of variable speed drive maintenance involve rotating clutches and bearings. It is important for these parts to be checked because they can cause the VSD drive not to work properly if they are worn out or damaged.
If any of these parts fail, it will be necessary for you to replace them as soon as possible so that your VSD can continue running without issue.
What are the benefits of VFDs?
Most variable speed drives are designed for motors that run at a constant speed. VFDs can adjust the motor’s output frequency, which in turn adjusts the motor’s speed. This means that energy costs can be reduced, and less wear and tear will occur on the equipment. VFDs also come with other benefits, like improved torque management, smoother operation and lower noise levels.
Conclusion
So, if you’re looking for a new way to lower your energy bills or cut down on your maintenance costs, it may be worth considering a variable speed drive. While they may not be the most affordable option out there, they are certainly one of the most effective.
