Two DC motors

[heirinchkkk]

Hi all!

I'm newbie and don't know how this thing can be done: Two DC motors with own drives. Speed needs to be adjusted from same potentiometer. Allso need to have integration (together for both drives). Speed difference between motors needs to be able to adjust. Hope you understand (...bad english!!)

Thanks

Sounds like what you want is master - slave system. The slave motor is some speed ratio to the master. Therefore if pot setting is adjusted both motors adjust but to the predetermined speed ratio. This speed ratio could be fully adjustable within the drives. I suggest you talk to your VFD Representatives. They should be able to help with the application.

Suggestion: This appears to be one control station controlling two motors each having its own adjustable speed reference setting. It appears that each motor will need its own feedback loop. The motor control drive manufacturer tech support could assist you with specifics.
