How many types of vfds are there?

Frequency converters are generally divided into four types: mini, general, vector, and special. Mini frequency converter: more suitable for customers who make small equipment. Mini frequency converters are characterized by exquisite appearance, easy operation, light weight, compact design, and excellent performance, suitable for some customers who make small equipment. General frequency converter: fully functional, powerful and stable, suitable for driving conventional loads: such as mechanical processing equipment, Roche blowers also need general frequency converters. Vector frequency converter: performance is better than general frequency converter, suitable for some loads with large inertia and requiring low-frequency and high-torque starting (to ensure that the load can run at low frequencies). Special frequency converter: Special frequency converter is aimed at specific industries.
