Danfoss Variable Frequency Drives

What Is a VFD?

A variable frequency drive is an electronic device used to control the speed and torque of an electric motor.

Instead of operating a motor continuously at a fixed speed, a VFD can adjust motor operation according to application requirements.

This can provide several potential benefits:

• Better motor control
• Improved process control
• Reduced mechanical stress
• Potential energy savings
• More flexible equipment operation
• Monitoring and control capabilities

Danfoss states that variable-speed control can support energy efficiency and decarbonization in suitable applications.
