V70 series solar frequency inverter

What is a Drive?
A Variable Frequency Drive (VFD) is a type of motor controller that rotates the electric motor by adjusting the frequency and voltage applied to it. Other names for VFD include variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter. Frequency (Hz) is directly related to motor speed (RPM); in other words, increasing frequency causes the motor to rotate faster and changes its RPM.
If you need an electric motor to operate below its nominal full speed, use a VFD to reduce voltage and frequency according to the load requirements. Thus, a VFD easily increases or decreases speed via frequency and voltage to match our needs.

Why Do We Use a VFD?

1. Adjust motor speed (RPM) based on load
2. Extend the lifespan of rotating components due to lower startup speed
3. Reduce energy consumption, especially at low speeds
4. Enable braking with reduced losses
5. Connect to industrial networks such as PROFIBUS
6. Issue commands via PID controller
7. Control and command via computer interface
8. Reduce noise and vibration
9. Minimize thermal and mechanical stress
