ac against dc
ac against dc
(OP)
hoping for some sound advice, existing motors on a machine are all d.c. permanent magnet 2 hp controlled by regen drives (4 quad), taco feedback. the system requires the motors to change speeds via pid control. the motors dont hold weight i.e. a lift system. i am building a copy type machine but considering using ac, what type of ac controller should i use to give the same performance. should the ac motor again be 2 hp like the dc version
any help will be light at the end of the tunnel

If regen is for braking, describe the braking application and maybe there is a less expensive way to go.

AC Vector drives offer excellent speed regulation at lower RPM. How much can you afford? Servos will attain the highest speed regulation and torque at all speeds!
The knowledge center at www.drivesmag.com is an excellent resource for drive and motor issues.

My preference would be Eurotherm 690+ drives.
