What is an AC drive?
Electric motors play a very important role in our everyday businesses and lives. They move and run basically everything we need for business or pleasure.
All these motors run on electricity. In order to do their work of providing torque and speed, they need the corresponding amount of electric energy. A motor's speed should match exactly what is required by the process.
Drives work by converting fixed frequency AC power into variable frequency, variable voltage AC power.
Here's how the drive does this:
1. Convert incoming AC to DC
2. Smooth the DC wave
3. Convert DC to variable AC
4. Calculate and repeat
