Fixed electromagnets will not have this effect. However, it should also work to some extent.
Note that at the maximum RPM - 3400rpm, the magnetic field changes 13,600 times per minute, at the moment the inverter is set to 42Hz which gives 2400rpm which is almost 10,000 anyway.
I'm afraid the electromagnets could get hot. After all, each switching on and off causes a "current-voltage" surge, but I may be wrong.
This solution would significantly reduce the size of the machine.
