    Filter Disassembly/Replacement

    Thanks for the info, it makes sense it would be glued. Is ripping out the glued element a standard procedure or normally/ideally would you just buy a whole new flange and filter assembly pre-glued? Got it, just by brushing and scraping a little they were cleaning up quickly and it seems like...

    Filter Disassembly/Replacement

    Hello, We are reassembling a grout plant and have dust air filters on the bentonite tank that I'm trying to find clean filters for. See photos here: https://imgur.com/a/921odKm I took off two threaded rods running from the top to bottom of the filter thinking it would come apart and the...

    Masters Degree ME vs EE Advice

    Thanks for the reply, Mint. A mechatronics degree does seem good for me (and also lines up with SW's advice for robotics). I'll do some research for reputable programs. Maybe schools are limited on first glance since mechatronics has a strong hands/physical focus. This would be good for me...

    Masters Degree ME vs EE Advice

    SWComposites, thank you for the post. I'll work on a longer term plan before I decide to apply. MintJulep, this is an interesting concept that I wasn't even aware of. I like the idea and think it would be up my alley but it looks like tuition is 175% the cost of either the ME or EE masters...

    Masters Degree ME vs EE Advice

    Hi all, I got a ME undergrad degree and have been working on a small team as a mechanical engineer for 2.5 years. I have been saving for and wanting a masters for over a year but have been waiting for the "perfect time" to ideally go in person. After some thought over the last few weeks I...

    DC Motor - Using Resistor to Lower Battery Voltage

    We weren't able to locate a 96V motor in the range of 10HP. Multiple suppliers told me 96V motors are very very rare, and it was hard enough to find one at 72 so I believed them. Would I need to get one custom manufactured?

    DC Motor - Using Resistor to Lower Battery Voltage

    I see the charging issue, thank you for the detailed response. Unfortunately removing cells isn't an option as the 96V battery pack powers an electric locomotive and my 72V machine is an accessory that gets powered intermittently. I will work with our electrician to get ideas and potentially...

    DC Motor - Using Resistor to Lower Battery Voltage

    Hi everybody. Thanks all who replied for the helpful info. This is a good lead, for future applications these may be a way to tune the speed for optimizing hydraulic performance. Edison and crshears, thanks for reminding me about this. This is no doubt the simplest and best solution. Our...

    DC Motor - Using Resistor to Lower Battery Voltage

    Hi all, I'm a new engineer working on upgrading a one off specialty piece of equipment. I didn't cover DC motors at all in school and I'm looking for some advise/reflection with a DC motor system design. This machine was designed multiple decades ago and has had a few redesigns/upgrades, but...
