FAQS about DC Industrial Frequency Inverter
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 inverter speed regulation work?
Inverter speed regulation is achieved by changing the frequency of the power supply to the stator winding of the motor. First, the rectifier section converts the AC power supply to DC power. This usually involves a rectifier bridge, which converts the AC voltage to DC voltage.
How a frequency inverter can improve the power grid?
Improve the Quality of Power Grid: when adjusting the motor operation, the frequency inverter can reduce the impact of the motor on the power grid, and reduce harmonics and the peak value of the current, which helps to improve the power quality of the power grid.
What is DC to variable AC conversion?
DC to Variable AC Conversion: Converts DC power back into AC with adjustable frequency (0–250 Hz). Operation Benefits: Rated motor torque is available at low speeds. Starting current is significantly reduced, typically between 0.5 and 1.5 times the rated current.
How does a frequency inverter change the speed of a motor?
Speed Regulation Function: Frequency inverters can change the speed of the motor by adjusting the frequency of the power supply. This is very important for applications that require flexible speed control, such as in industrial production, where different production processes may require different speeds.
