Introduction to DC Drives
In this video we take a look at a small DC drive. It will show you the basics of how a drive is controlled and how it operates. This will be helpful for anyone entry level industrial electricians or engineers that haven't had any actual hands on experience with drives.

Introduction to Ice Cube Relays
Переглядів 46 тис.8 років тому
This is a basic overview of the ice-cube relays that an industrial electrician or engineer would be expected to work with.
Why do they have vacuum tube bases? Octal base tubes would fit in those. Hmmm.
Careful with the verbiage. The contacts don't change state from NO to NC. NO contacts close, and NC contacts open, but they don't go from NO to NC. That can be very confusing for someone just starting to learn about switching and relays and stuff I know it was for me.
Went to school there in 2008. Great ROBOTs , nice facility , good instructors and staff. Just as you would expect from FANUC.
How does this not have more views
I've got an old Manerick DC drive I've struggled to hook up (w/confidence) So I've settled on using A Variac auto transformer.. My question, why not use a Variac with contactor instead? Is my variac (with a bridge rectifier of corse ) bad for my 90volt DC motor? It's a Minarik blue label
Stranded that s me.. but I can't find any videos explains how a drive works to the extent I can grasp what and how it should be wired to the motor. My drive has brake ff and Rev btw
Your voltmeter was measuring over 90 VDC. Wouldn't that damage the motor? Can you explain what is happening. Thanks for this!
Over time possibly, but typically they can handle some over voltage. I guess the way I think of it is that whatever the rating is of the insulation inside the motor determines what it can really handle lol. Giving it more voltage from the DC drive makes the motor more powerful...Faster. plus it's fun.
Thanks bro.
Would you mind sharing a power schematic and control circuit so I could get a better understanding? Great video btw
Where do you buy the heavy duty rotary switches and the large indicator lamps?
In would try automationdirect.com . They have great prices.

great video, very clear walk through
Thanks, i do hvac and i see these relays in most units now. Now i can work on them without panicking when i see them.
Nice Video.
