Tips: Choose a VFD base on motor rated current
When a motor power is stated, it is always the mechanical power, shaft power i.e. NOT the input electrical power.
Variable frequency drives (VFD) are also (mostly) rated in terms of kW albeit it's wrong. Because VFD output is electrical (not mechanical). Mechanical power (i.e. motor shaft power) is always "active" power, where in electricity we also have reactive (doing nothing but losses) power. The apparent (total) power (stated in terms of kVA) is vectorial sum of active and reactive power components.
For all those facts above, ATO highly recommend to select a VFD by matching motor current. This is the right way. Despite mathematically correct, we wouldn't select a VFD for partial load of motor. We would simply go for motor nominal (rated) current.
Finally the answer is: choose a VFD output current ≥ motor rated current.
