Inverter drives, also known as variable frequency drives (VFDs), are essential components in modern industrial and commercial applications. These intelligent devices provide precise control over motor speed and torque, offering a multitude of benefits. Inverter drives improve energy efficiency by allowing motors to operate at optimal speeds, resulting in significant energy savings. They also enhance process control, enabling smooth acceleration and deceleration, reducing mechanical stress on equipment, and extending their lifespan. With advanced features like built-in diagnostics and remote monitoring capabilities, inverter drives facilitate proactive maintenance, minimizing downtime and improving overall productivity. Whether used in HVAC systems, pumps, fans, or conveyors, inverter drives offer a cost-effective and efficient solution for controlling motor speed and optimizing performance.

We offer a wide range of inverter drives available with different IP Ratings. See our guide for more information [https://uk.rs-online.com/web/generalDisplay.html?id=ideas-and-advice/ip-ratings](https://uk.rs-online.com/web/generalDisplay.html?id=ideas-and-advice/ip-ratings)

### How do inverter drives work?

Inverter drives are controlled by inputting specific frequencies or parameters into the device. This allows for greater control over your machinery and operations with more precision. Inverter drives are situated between an electrical supply and a motor, with the inverter allowing the power to be regulated to suit the application.

### Features and Benefits
- Control small appliances such as desk portable fans or pump loads
- Larger appliances such as high torque machine control
- Digital operation LED input screens (for easy parameter setting, input and monitoring)
- Compact and sleek design
- Easy installation
- Emergency stops
- Energy-saving

**Where might I use an inverter drive?**

Inverter drives are used in a wide range of industrial applications. Inverter drives are particularly useful for applications that require precise control of speed and torque with motors.

These kinds of drives are used in areas such as small appliances like simple fan and pump loads all the way through to high torque machine control applications.

**What is the difference between VSD ( variable Speed Drive) and VFD ( variable frequency drive)?**

VSDs change the speed-driven equipment while leaving the motor to operate at its full design speed.

VFDs control motor speed by varying the voltage and frequency applied to the stator of a standard AC motor. VFDs can vary speed control at start up, during the run, and at motor stop.

They can also be known as Variable Frequency Drives (VFD's), AC drives, Variable Speed Drives (VSD's), or frequency converters. They sit between the motor and the electrical supply and regulate the power which is sent to the motor. They are highly beneficial for energy saving as you can adjust the speed of the motor by gradually increasing or decreasing the power which is fed to it through the drive, ensuring better energy efficiency. For example, instead of applying full power to a motor during start-up, it can be supplied gradually.You'll find popular series from Eaton's offer here at RS such as the PowerXL DA1, DE1, DC1, and DG1 drives. Eaton drives come in a variety of power ratings and you can choose from 1 up to 3 phase types, with mounting options such as panel mount or DIN rail to suit your installation requirements.
