VFDs for electric motors
A variable frequency drive gives precise speed control, smooth startup, and lower inrush current for electric motors. This improves reliability and energy efficiency across industrial applications.

How to select a VFD for a motor
Match the drive to motor rated current first, then power, load type, supply voltage/phase, and required control mode (V/F vs vector). For hard-start and low-speed torque, vector control is preferred.

FAQ
Why is motor current more important than kW only?
Current is the key sizing parameter for reliable drive operation.
When should I use vector control?
For demanding startup conditions and stable low-speed torque.
What does smooth start improve?
Lower mechanical shock and reduced peak current.
Why does motor noise increase at low frequency?
Usually due to incorrect motor data or PWM settings.
