By changing the frequency provided by the frequency inverter, the speed of the motor can be adjusted. If we want to increase the speed of the motor, we increase the output frequency of the inverter. Voltage Control: Along with frequency control, the inverter also adjusts the voltage of the output AC.
Frequency Control: The frequency of the output AC voltage is determined by the switching frequency of the IGBTs in the inverter stage. For instance, if an electric motor is designed to operate at a synchronous speed of , where is the speed, is the frequency of the power supply, and is the number of poles of the motor.
A frequency inverter’s primary function is to manage motor performance by adjusting the electrical supply, but the way it does this can vary depending on the method of control used and the motor''s specific demands. Here''s a breakdown of how frequency inverters influence motor performance:
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).
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
A frequency inverter adjusts the frequency and voltage of AC power to control motor speed, making it ideal for industrial applications like manufacturing and HVAC systems.
