I think that DC motors are cheaper to control and more accurate for speed but more expensive than AC motors and have larger size for same power output.

Certainly DC drives are cheaper to control, AC drives are cheaper to buy in any size bigger than 1/2 horsepower (~374 Watts)

Personally, I like the Siemens Micromaster 420 inverters, they are only single quadrant, but so much fucntionality in such a small box ! RS232 interface as standard, RS 485 as an option. Absolute magic.

We're using the 1.5kW and 5.5kW units.
