Single Phase VFD with 220V input/output

Note that this speed control method works by weakening the motor so that the load forces the motor to operate at a reduced speed. If the load varies, the speed changes. If the load drops to zero, the motor goes to full speed. Without a load, there is no speed variation.

When to use a Soft Starter or an AC Variable Frequency Drive

6/10/2014†∑ Is there a rule of thumb limit to how fast you can run a three phase motor? If a 2 pole motor runs at about 3500RPM, and a four pole runs at 1750 here in the US on 60hz, are the 50 Hz motors standard speed options something like 2850 and 1425? Or is there some way to make a 3Ph motor run at 3500 rpm on 50Hz?
