Answer 1

Concept: Principle of VFD

1. The design of VFDs comes in a variety of shapes and sizes.
2. The VFD's primary function is to convert a constant frequency and voltage into a variable frequency and voltage.
3. There is a change in the speed, torque, and direction of the inductive motor which gives us a variable result.
4. The motor's average speed can range from zero to one thousand revolutions per minute $100-120\%$ of its full rated speed.
