What are the application scopes of VFD and soft starter
Frequency converters and soft starters have different application scopes and characteristics in motor control:
Application scope of frequency converter (VFD)
Industrial automation: Control motor speed in production lines, assembly lines, etc. to optimize production processes.
Pumps and fans: Regulate flow and pressure to achieve energy saving.
HVAC system: Control fans and pumps in air conditioning and ventilation systems to improve energy efficiency and comfort.
Elevators: Achieve smooth acceleration and deceleration of elevators to improve safety.
Electric vehicles: Regulate the drive of motors to control acceleration and deceleration.
Food and beverage industry: Used in mixing, packaging and transportation equipment to ensure production efficiency.
Application scope of soft starter
Motor starting: Used for smooth starting of high-power motors to reduce starting current and mechanical shock.
Pumps and fans: Avoid water hammer effect and vibration of fans during starting.
Conveying system: Smoothly start and stop conveyor belts to protect equipment and loads.
Elevators and cranes: Control the starting and stopping process to ensure safe and smooth operation.
Agricultural machinery: Such as starting of pumps and fans to protect equipment from overload damage.
Summary
Inverter: Mainly used to adjust the motor speed and torque to achieve efficient control.
Soft starter: Mainly used to reduce the current shock and mechanical shock when the motor starts to protect the equipment.
Both can be selected and used according to specific application requirements, and can even be used simultaneously in some systems.
