How to Select the Right VFD for Motor Control

When selecting a Variable Frequency Drive (VFD) for your manufacturing application, consider the following product attributes. We’re standing by with answers to your questions and will guide you toward the right solution.

What Input Voltage matches your power needs?

The VFD must match the input voltage of your facility's power supply. Selecting the correct input voltage ensures compatibility and efficient operation.

What Input Phase (AC)?

The VFD's input phase (single-phase or three-phase) should align with your facility's power system. Choosing the right input phase is essential for seamless integration and optimal performance.

What Input Frequency matches the power supply?

Matching the input frequency of the VFD with the power supply frequency is crucial. This ensures that the drive can accurately convert and control the motor speed in your manufacturing equipment.

What is the Maximum Output Power required for your motor?

This represents the VFD's capacity to handle the power demands of your motor. Select a VFD with a maximum output power rating that exceeds the requirements of your application to avoid overloading the drive.

What is the Maximum Output Current needed?

Like maximum output power, the maximum output current indicates the drive's ability to handle the current demands of your motor. We’ll help with selecting a VFD's current rating that meets or exceeds the requirements of your gear.

What Output Voltage matches motor voltage?

The VFD's output voltage must match the motor's voltage requirements. Correct voltage compatibility ensures efficient energy transfer and prevents damage to the motor.

Single or three-phase (AC)?

The output phase of the VFD (single-phase or three-phase) should match the motor's requirements. This ensures that the motor receives the correct phase configuration for smooth and reliable operation.

Enclosure Rating needed for your environment?

The enclosure rating specifies the environmental conditions so the VFD may work safely. Consider dust, moisture, and temperature in your manufacturing plant when selecting a VFD with the right enclosure grade for dependable and durable operation.

Evaluating and selecting a VFD based on these attributes, helps us see that the drive is well-matched to your application. This gives you efficient operation and extended electrical equipment life.
