Does your mag drill base get HOT?

Hi,


I got a Vevor mag drill for my home shop. I've used it a few times and it works fine. However, when the magnet is switched on it gets HOT (97 degrees F after a few minutes and 130 degrees F and rising after 26 min). This is WITHOUT the drill motor running. I Messaged Vevor and they said my drill is functioning as designed: "... the magnet is working is hot, can not touch, this is a normal phenomenon, please rest assured that the use."


Does this happen with other brands?


Thx,


ZLT

I would say it's normal for an import mag drill. I wouldn't consider 130 as hot .

My mag is American made with real copper windings. It will get a little warm when drilling hundreds of 9/16 or 11/16 holes.

The new ones probably use less windings to cut cost. They are using a high temperature lacquer on wire windings to use less copper and aluminum too.

No, a well-designed electromagnet should not get hot. Nearly all the energy should be converted to magnetic force, not converted by resistance into heat.
I have only used a few, one not even a Brand Name unit, and none got more than slightly warm.

'Course, this was in the Old Days, with Old Electricity (more from Nuclear and Coal-fired plants) so maybe that's the difference? :dizzy:

My Hougen has always gotten hot, if i leave on for an extended period of time. Mine is not too hot to touch, but substantial heat build up, not simply warm. It will heat up the 1” pad it rear on too. Isn’t it essentially a transformer?

I notice this with my toaster,,
Back 10 years ago,, the toast would get black,, from the coal fired electricity,,
Several years ago, our electricity switched to nuclear supplied energy,,

If I make toast in the middle of the night, after an evening of bar hopping,, I notice the toast has a glow to it,,,
Hmmmmmmmmmm,,

On a side note,, "FEELING" the base is not a good method to determine the temperature,,
The threshold of pain from heat is 120 degrees F,, which is not much,,
I guess it is time to get out the digital thermometer,,

Yep, my Vevor resting in front of the window is 20C (68 F). After 10 minutes on, but not drilling, it's 24C (75 F). After 20 minutes it's 27C (80.6 F) so it's not even warm to the touch since body temp is up around 98F. That's probably the longest I've left it on without being in use since I got it... I think that's kind of frowned on for the magnet.

Not exactly.... electromagnet...

I'm getting all kinds of ads from Vevor for "Hot Deals".... perhaps I misunderstood...

So, they do heat up. If one is drilling 100 holes in a drill press setup, then the magnet will likely not be turned off after each hole. Unlike moving it per hole.

Side note: I had an opportunity so demonstrate the power of electromagnets utilizing my Mag drill. It was in an 8th grade physical science class. We lifted a lab bench with it.

Yes, just as motors heat up slowly when running a long time...but the OP's unit is getting hot much faster than that.

Even with a similar unit, I have never felt the base getting hot enough to be noticeable... but I don't usually leave it on for extended periods of time. It did a lot of drilling when I was putting the 5/8" holes in the moldboard for the snow blade, but it was also shut off to move it between holes. I suspect that electromagnet is doomed to have a shorter than average life span. Keep it documented with Vevor so if it does let out the magic smoke early, you may have some recourse. It depends on how often you use them. I doubt I will ever wear mine out with only periodic use, but it sure is handy when you need it.

In my experience, Vevor customer service sidestepping product concerns is a “normal phenomenon” :laugh::laugh::laugh:

I am NOT a fan of vevor. I bought a 35 gal fuel caddy and the two bungs for the pump and fill weren't welded. Well after sitting over the winter I filled it up with gas. My $12k Bad Boy zero turn stopped about 30 feet after I filled it up. Had to flush out the entire fuel system, lost over 30 gallons of gas, lost the price of the pump.....vevor refunded me less than half of the cost of the caddy, for a defective unit! They WILL NOT stand behind their products. They lost a lot of money, because I made quite a few purchases that could have been from them.

Anyway, I never really paid attention to my Hougen, but I can't remember it ever getting hot to the point I would notice it.

My hougen came with a safety chain. I have used ratchet straps to support it in different positions, thin metal or non ferrous metal. So, there is a thought if you are stuck with it.

Mine get hot over a long time (hours) and it will be noticeably hot. No issues with holding, it is near 20 years old. It when in use it sits idle as much as it drill, if in drill press mode.
