ZFeng 900 Series 75Kw-T-P General Vector Variable Frequency DriveThe frequency converter is mainly composed of rectifier, filter,
inverter, braking unit, driving unit, detection unit, and
microprocessor unit. The core working principle is to adjust the
voltage and frequency of the output power supply by disconnecting
the internal IGBT (Insulated Gate Bipolar Transistor).
Specifically, the frequency converter first converts the input AC
power into DC power, and then converts the DC power into AC power
with controllable frequency and voltage for use by the electric
motor. Core Functions- Speed regulation function: The frequency converter can adjust the
voltage and frequency of the output power supply according to the
actual needs of the motor, achieve stepless speed regulation, and
meet the precise requirements of various production processes for
motor speed.
- Energy saving function: By precisely controlling the speed of the
motor, the frequency converter can avoid wasting electrical energy
when the motor does not need to run at full speed, thereby
achieving significant energy-saving effects. For example, in square
torque load scenarios such as fans and pumps, the energy-saving
effect of frequency converters can reach 30% to 60%.
- Protection function: The frequency converter has multiple
protection functions such as overcurrent, overvoltage, overload,
etc., which can ensure the safe and stable operation of the
equipment in abnormal situations, effectively protecting the motor
and frequency converter from damage.
Purchase SuggestionsWhen choosing a frequency converter, enterprises should
comprehensively consider factors such as the characteristics of
production machinery, the required speed range, the accuracy of
static speed, and the requirements for starting torque. At the same
time, it is also necessary to pay attention to the power matching,
environmental adaptability, and compatibility with other devices of
the frequency converter.If you have any technical questions or
