Medical devices and US 220V electrics

No, reality. No one makes/sells 240V lawnmowers & snowblowers here, because they would require outlets that most houses lack.

(If I was building myself one it would have a 3-phase motor with the VFD back at the garage.)

My lawn guy uses gasoline >:-} ...Jim Thompson

If you have 240V (or 120V) you also have three phase feed nearby. There is nothing that says you have all three (of the phases), in any of the above cases.

Why go to all that work? Just use a rotary phase converter (an idling three phase motor) to get the third phase. Personally, I wouldn't go near such a snow blower. Gasoline works great. OTOH, I would never go near a snow blower again (or snow that needed a snow blower).

This medical device...

is at Ironwood Cancer and Research Centers.

I don't believe it plugs into an outlet >:-}

I visit it daily for 15 minutes to get my dose of RAD's. In fact the form on the table is my personal molded shoulder and head restraint so I don't try to move ;-) ...Jim Thompson

And it always starts in subzero weather, does not need you to keep fresh gas, never needs the oil changed......

A rotary converter is *easier* than a VFD? Not in my book.

That reminds me of my first job in the industry. We built CAT scanners as shown by the renderings on this page:

The rendering in the left panel shows the operator's table. The rightmost device on it is a plain old camera for snapping pictures.

Our CAT scanner used 220V. That said, the room that housed it was custom built for it. The room that houses your medical device was probably also custom built for it.

Thank you,

Gas? Oil? WTF are you talking about.

Of course it's easier. It's just a motor. It's done all the time for surplus woodworking machinery. VFDs are expensive.

I *have* an electric lawn mower, think it is only 1kW or so, the kind you need to push (or pull) what is the problem? Now much snow here lately (last 10 years or so that I can remember), eh make that last 40 year, eh make that last 60 years... Oh well.

Those electric movers are OK, just plug it in and it works. Cleaning it after mowing is most of the work.

The nice feature of those small movers that you cam easily carry them from one place to an other, while gas powered devices needs to be dragged from place to place.

At power levels around 1 kW (1.5 hp) , the current drawn from 230 V is only 5 A. Since the mover are double insulated no protected ground

sufficient.

I also have a snow blower with an engine with several horse power engine. Even so, it sometimes has problems handling thick snow. To do it electrically would require a 3 x 16 A 230/400 V socket somewhere in the house (not that uncommon here, but perhaps not outdoors). Anyway, the thicker cable would be awkward to handle, especially at cold days.

There is a guy in a boating group here who uses 4 of those lawnmower type motors to replace a diesel for his boat, and it actually works.

Mixed results, but it works. Huge batteries, converter.

A dinky 18" mower and a HUGE yard don't mix, IMO. Also, be sure the blade stay sharp and you don't let the yard go (vacation, monsoon week, or whatever). Tall, wet, grass won't be fun.

The reasons I want to be rid of gas mowers....

Such as the one at the Dayton Hamvention for $20.... Electronics are cheap; iron, copper, bushings, and frames cost. And a FVD is far more capable....

Why on Earth would you want to do that?

Electronics aren't cheap. Surplus motors are.

Hi, Nice discussion is going on. But according to me before selecting any medical cable you have to first go through its quality & material & how much I know medical cables from Peter's Technology is one of the best choice among all. Thank you.

Hi, Nice discussion is going on. As I haven't worked with NEMA 6-15 220V but ac cording to me before selecting any medical device you have to first go thro ugh its quality & material. You have to choose medical devices by checking it's certifications like FDA registered, ISO certified, CSA recognized. How much I know medical devices from Peter's Technology is one of the best cho ices among all. They have got so many trusted certificates for their qualit ative medical devices. Thank you.

Is this a business plug ?
