ZFeng 900 Series 450Kw-T-P General Vector Variable Frequency Drive
The frequency converter is the core equipment for motor control, which achieves precise control of the load by adjusting the motor speed and torque. It is widely used in industries such as industry, energy, and transportation. However, Frequency converters and motors are two core components closely related to modern industrial automation and power transmission systems.
The function of frequency converter on motor
Speed control
Principle: The frequency converter achieves stepless adjustment of motor speed by changing the power frequency of the input motor.
Advantages: Compared to traditional mechanical speed control methods such as belt drive and gearbox, variable frequency speed control has the advantages of wide speed range, high precision, and high efficiency.
Application: Equipment such as fans, water pumps, and conveyor belts that require speed adjustment according to load changes.
Energy conservation
Principle: When the load changes, the motor adjusts the speed through a frequency converter to match the output power of the motor with the actual load demand, avoiding the phenomenon of "big horse pulling small car".
Advantages: Significantly reduce energy consumption and improve system efficiency.
Case study: The cooling water pump in the central air conditioning system, which adjusts the speed according to the cooling demand through a frequency converter, has a significant energy-saving effect.
Soft start and soft stop
Principle: The frequency converter starts the motor from low frequency and low voltage, gradually increasing the frequency and voltage to accelerate the motor smoothly to the set speed.
Advantages:
Reduce the current surge during motor start-up and extend the lifespan of motors and mechanical equipment.
Reduce the impact on the power grid and avoid voltage fluctuations.
Application: High power motors with strict limitations on starting current.
Torque control
Principle: The frequency converter can accurately control the output torque of the motor to meet the torque requirements under different working conditions.
Advantage: Improve the operational stability and reliability of the equipment.
Application: Equipment that requires constant torque control, such as winding machines and elevators.
Protection function
Principle: The frequency converter is equipped with various protection functions, such as overload, overvoltage, undervoltage, overcurrent, overheating, etc. When abnormalities are detected, the power supply is cut off or the output is adjusted in a timely manner.
Advantages: Protect motors and equipment from damage and improve system safety.
