Technical FAQs 4

What is a frequency inverter?

The frequency inverter is a power control equipment that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor power supply.

How does a frequency inverter control a motor?

By adjusting the output frequency,the frequency inverter directly controls the motor's rotational speed. Lower frequency=slower motor speed.Higher frequency=faster motor speed. Why go through all this trouble to control a motor?The benefits are substantial:

Can a frequency inverter run a motor above 50Hz?

While most motors are designed to operate at a frequency of 50Hz, there are many situations where higher speeds are necessary. Frequency inverters provide the flexibility to run motors above 50Hz, allowing for increased operational speeds and improved performance in certain applications.

How does a frequency inverter convert fixed power to variable power?

The process of converting fixed power to variable power involves three key stages: Rectification (AC to DC):The frequency inverter first takes the incoming Alternating Current (AC)power and converts it to Direct Current (DC)using a component called a rectifier.This DC power is stored in a DC bus (a set of capacitors).
