Variable Speed Drives, which are also known as inverters, allow the user to adjust the speed or output. Variable speed drives provide the user with precise control by allowing the AC power to be converted to DC.
With variable speed drives, it helps to reduce unnecessary wastage of electrical energy from the applications.
So, how do variable speed drives operate?
Variable speed drives are controlled by inputting specific frequencies or parameters into the device that allows greater and precise control over the machines and operations.
Variable speed drives are usually placed between an electrical supply and a motor, with the inverter allowing the power to be adjusted to suit the application.
Variable speed drives can be used widely in various applications, from small applications such as desktop fans to industrial applications. It is particularly useful for applications that require precise control of speed and torque with motors.
Some variable speed drives are very compact and sleek, making installation at ease. Some may have built-in security features such as automatic restarts after power failures, emergency stops, or safety self-diagnostics that allow the user to identify and prevent any workplace accidents.
