3-phase question

[speirmoor]

I used to stuff hand warmers in my gloves and boots, even in my pockets. I still use them in work gloves when working outside in the cold. The 7 volt stuff is probably useful for its portability. My loader's 60 amp alternator was hardly working. Yeah, they're a little too much for the bike now but LEDs will free up the amperage I need.
I wonder how the police bikes handled tube radios, emergency lights and siren?

What LEDs are you using? I need to get some if you have a link

 

[kommando]

But what is in the plastic bag to warm it up. Best not answered :}

Great products, great service:

If you are converted to negative earth, these are the stuff:

You can rewire the headlight hi low switch and use a negative ground led bulb. Not a big deal

On my G15 I have added a higher output stator and solid state regulator/rectifier. With a led headlamp there is plenty of juice left over to heat the heated handgrips I’ve installed.

I’ve taken to wearing a Alpinestars airbag vest which is warm enough to have reduced my need for the electric vest….. but I can’t seem to get on without the heated grips.

 

[hhh]

Note that the original rectifiers and regulators were solid state.

Good point...

 

[Elfix]

I moved to “Modern” solid state?

Note that the original rectifiers and regulators were solid state.

Semantically correct in that the original bridge rectifier (four discrete diodes) and Zener diode were no not tube devices and were in fact made of discrete solid state diodes.

In reality, "Solid State" today often refers to integrated components rather than discrete components such as resistors, capacitors, diodes, transistor, etc.

Calling an all-in-one rectifier/regulator solid state to differentiate from the bridge and Zener is fine in my book. I'm happy to just call it a voltage regulator too, even if that is inaccurate and I usually call the Tri-Spark version a MOSFET Regulator which is also inaccurate.

The modern regulator/rectifier is even solider.

Rock-solid state!

No, this is not semantics. This is a widely accepted definition: "solid state electronics are semiconductor electronics." This does not include resistors, capacitors or inductors or any other non-semiconductor based device. Tri-Spark manufactures MOSFET regulator/rectifiers, but I have no idea if they're all MOSFET based.

NON solid state voltage regulator.

 

[hhh]

That is indeed a non-solid state regulator. Just to be clear, this is the Commando forum, so all my comments are in that context. No Commandos were equipped with anything other than solid state rectification and regulation.

Correct. I was illustrating that the contemporary sales competition was using NON solid state.
For the purpose of defining to those folks reading this thread who are unsure why the term "solid state" was being used.

Lucas gets a lot of flack, but they were really the leading edge of modern and reliable electrics in the sixties (ok, maybe not their switch gear.) How many vehicles are running around now with their original 50-year-old charging systems still functioning?

Most earlier rectifiers/regulators are in-part SCR based. The input to a Tri-Spark VR-0030 is three individual MOSFET devices and since they are integrated circuits, they are not discrete transistors.

Semiconductors absolutely include transistors - nit-picking a sentence is not nice.

The term "solid state" meant something VERY different before semiconductors were introduced and it was applied to diodes and transistors initially to differentiate between vacuum tube diodes and triodes (same basic function as a transistor).

I agreed with you but language changes over time.

Some of the many definitions - this one from Merrium Webster (notice 2b):

1
:relating to the properties, structure, or reactivity of solid material
especially : relating to the arrangement or behavior of ions, molecules, nucleons, electrons, and holes in the crystals of a substance (such as a semiconductor) or to the effect of crystal imperfections on the properties of a solid substance
solid-state physics


2
a
: utilizing the electric, magnetic, or optical properties of solid materials
solid-state circuitry

b
: using semiconductor devices rather than electron tubes
a solid-state radio

Yes, and I contend that any switch gear exposed to the elements that still works 50 years later is very good. I rarely come across a pre-75 switch console that I can't make work right.

Interestingly, colleges were still teaching tubes and only touching on semiconductors in the late 60s/early 70s an our old motorcycles had solid state bridge rectifiers and Zener diodes. I rode to college on a Triumph 500, then learned all about tubes - only had one class in semiconductors and it was the only electronics class with no lab, so no hands on.

 

[hhh]

I was not nitpicking when I excluded passive devices from the class of semiconductors. They are discrete devices, as are transistors and diodes, but unlike transistors and diodes, they are certainly not semiconductors. "Discrete" and "semiconductor" are two completely independent qualities and an electronic device can be neither, either or both. Of course "solid state" used to only mean not liquid, gas or plasma, and it was used to distinguish from thermionic devices which makes perfect sense since in these electrons pass through a near vacuum, but in a semiconductor, they pass through solid matter. Some refer to tubes (valves for those in the UK) as "hollow state."
