Thoughts on Induction motor bogging down

On my belt sander. Never used to do this that I recall. Sat a few
years, now it seems to bog down just sanding pine with moderate
pressure.
It is a 1/2 hp 3450 RPM. Not sure of the brand. Should I try blowing
out the dust?
Thanks, Tony

It's well worth taking apart something like that and cleaning out the dust.
I can't tell you (because I haven't counted) how many things I've been able
to fix by taking them apart, cleaning them, and then reassembling applying
proper lube where required.

So far nothing but a long list of engine regulations..not peek-worthy.

This reminds me of people wondering why they can't ski behind a 9

In fact, I will write a song about that tonight.

If, in fact, it's doing it now and not before, I'd check belt tension and

Doesn't take much over tightening of the belt to make a 1/2 hp motor complain..

If you are referring to the video comparison between the 225 HP 4
stroke and the 225 HP 2 stroke, I assure you that there is something
magical when it comes to a high HP 2 stroke engine and bottom end
torque.
Even a small 250 cc two-stroke dirt bike has capabilities that most
400 cc+ 4-strokers can only dream about.

That is... fuel consumption and pollution aside... there's always a
trade-off. I have no idea what Evinrude has done to the concept of two-
stroke engines to make them more palatable, but I am about to find
out.

Prop matching is still hampered by limited RPM ranges though.

My comment was directed at the application.

Sailboats (heavy load) require large props, often 4 blade, relatively
low RPM while ski boats (Light load) require smaller props, 2 or 3
blade and higher RPM.

Different horses for different courses.

Since California outlawed 2-stroke engines except foor leaf blowers,
and California represents in excess of 10% of the available market,
why would anybody pursue a
2-stroke product?

Shades of a Detroit mind set.

Keep building tin cans with bigger tail fins.

I couldn't agree more. But you're talking different horse-shoes for
different courses.

The prop geometry is determined by the power-band of the motor as well
as the load it is pushing.
There isn't a prop that does it all, hence controllable pitch props
(which, as I'm sure you know, are not the same as variable pitch
props). That holds true in all mediums, air, water, etc.

I think 2 stroke technology is much maligned because "they smoke".
I'll take a clean running 2 stroke over a beadly designed/running 4
stroke any day.
Then again, I still listen to vinyl, wear real leather and drink beer
from glass only.

....and.... two-stroke diesel is moving a shitload of freight around
the planet.

Do you have brushes ? Perhaps you have a problem with one or both.

Is the cord in good shape - it might have corroded over the time.

Strictly under peckered for the application.

You need at least 1 HP, better yet 1-1/2HP, 1800 for a belt sander
application.

A 1/2 hp 3450 RPM motor is not good for much more than cooling fan
duty.

In California?

Snow blowers are only needed around the ski resorts along with the
snow making equipment.

Translation:

Snow is restricted to the mountains.

Back pack mounted leaf blowers are a way of life.

Commerical yard service companies couldn't survive without them.

A lot of chain saws have larger engines.

If you limit 2-stroke product below 25HP, you have covered at least

A 1/2 HP induction motor is not really enough for a stationary belt
sander. And if it is actually 'slowing down' when using it, it is
likely that the squirrels have left the cage (so to speak). Besides,
for that job, a 2 pole motor sucks.

The whole point of a belt sander is that you set up an argument
between a motor and a brake. The motor is supposed to win by wearing
away your wood.

I HP minimum, or a quality 3/4 HP at -1800 RPM and pullied up to
whatever speed you want your belt to run at.

Lets see now, WestMarine(Retail)/PortSupply(Wholesale) based on the
left coast and Defender Retail/Wholesale on the east coast represent a
major portion on the recreational marine market in the USA and neither
represents Evinrude.

Sounds like a successful marketing plan to me.

The Japanese have been major players in the off shore market for
several years now.

More 2-cycle development seems like a good place to invest.

Check again. California has no laws or regulations that prevent the
use of two-stroke engines. Their regulations are performance
standards and any engine that meets them when tested per the
regulations is allowed. The CARB site contains numerous mentions of
compliant two-strokes.

Further, there is no exemption for leaf blowers, perhaps you are
thinking of snow blowers?

If you're going to spout off about California regulations, at least
LEARN WHAT THEY SAY first.

This is pretty much the case for chain saws and other small engines,
and there may be technical issues that make a clean small 2 cycle
impractical. Or maybe the manufacturers just can't be assed to do
anything about it.

Evinrude (or more precisely Bombardier) is using direct injection
(note--not direct _port_ injection but timed direct injection into the
cylinder like a diesel) to achieve clean enough combustion to meet
emissions standards. Supposedly their new outboards are cleaner than
the competing 4-strokes.

Note that this isn't your little 3 horsepower Lightwin we're talking
about--power output on current-production Evinrude outboards starts at
25 hp and goes up to 300.

Meanwhile in smaller outboards BRP seems to have only one model, a 9.9
HP four-stroke sold under the "Johnson" brand, that isn't a whole lot
more portable than a 25 HP Evinrude, so apparently they've also
decided to abandon the under 25 HP market (note that California regs
have a demarcation point at 25 HP, but I don't know if the
requirements change sufficiently to make under-25-HP engines more
difficult to bring into compliance than over 25).

Nope. If the two-stroke manufacturers can make the engines pass regs
they're welcome.

Yes, in California. If you don't like it take it up with CARB, I
don't make the regulations.

The low utilization and their use only in winter is the reason they
are allowed.

Well, this is a nice rationalization, however in the real world
several leaf blower manufacturers have been forced to exchange
noncompliant leaf blowers for compliant ones, and many localities have
banned gas powered leaf blowers outright. Further, in the real world
the California regulations specifically exempt snow blowers, so it
would appear that you are a bit confused on what kind of blower is
exempted.

And what does the size of chain saw engines have to do with anything?
If they're larger than 25 horsepower it might make a difference under
the regulations but beyond that I fail to see your point.

Lew, you're talking through your hat.

Evinrude seems to have pushed that rope successfully. So do several
other manufacturers by using catalytic converters, stratified charge,
and other technologies.

I'm sorry, but I still don't understand your point. There are no
exemptions to emissions laws in California based on "size".

Which has exactly what to do with your assertions concerning "size"?

Maybe you should start.

The bottom line here is that you have some kind of perception of the
California emissions regulations which is at variant with the reality.

The exemptions are spelled out in the regs:

2401(a)(37)“Small off-road engine” means any engine that produces a
gross horsepower less than 25 horsepower (at or below19 kilowatts for
2005 and
later model year), or is designed (e.g., through fuel feed, valve
timing, etc.) to
produce less than 25 horsepower (at or below19 kilowatts for 2005 and
later
model year), that is not used to propel a licensed on-road motor
vehicle, an
off-road motorcycle, an all-terrain vehicle, a marine vessel, a
snowmobile, a
model airplane, a model car, or a model boat. If an engine family has
models
below 25 horsepower (at or below 19 kilowatts) and models at or above
25
horsepower (above 19 kilowatts), only the models under 25 horsepower
(at or
below 19 kilowatts) would be considered small off-road engines. Uses
for small
off-road engines include, but are not limited to, applications such as
lawn
mowers, weed trimmers, chain saws, golf carts, specialty vehicles,
generators
and pumps. All engines and equipment that fall within the scope of the
preemption of Section 209(e)(1)(A) of the Federal Clean Air Act, as
amended,
and as defined by regulation of the Environmental Protection Agency,
are
specifically not included within this category. Any
compression-ignition engine,
as defined in Section 2421, produced during the 2000 and later model
years shall
not be defined as a small off-road engine."

209(e)(1)(A) exempts "(A) New engines which are used in construction
equipment
or vehicles or used in farm equipment or vehicles
and which are smaller than 175 horsepower."

2403(b)(5): Engines used exclusively in snowthrowers and ice augers
need not certify to or comply
with the HC and NOx standards or the crankcase requirements at the
option of the manufacturer.
(6) Engines used exclusively to power products which are used
exclusively in wintertime,
such as snowthrowers and ice augers, at the option of the engine
manufacturer, need not certify to or
comply with standards regulating emissions of HC+NOx or NMHC+NOx, as
applicable. If the
manufacturer exercises the option to certify to standards regulating
such emissions, such engines
must meet such standards. If the engine is to be used in any equipment
or vehicle other than an
exclusively wintertime product such as a snowthrower or ice auger, it
must be certified to the
applicable standard regulating emissions of HC+NOx or NMHC+NOx as
applicable."

The full text of the regulations can be found at
http://www.arb.ca.gov/regact/sore03/2fro.pdf and
http://www.arb.ca.gov/regact/sore03/1fro.pdf.

If you can find anything in either of them that exempts leaf blowers
please do let us know.

You might also want to inform the leaf blower manufacturers, as they
have been laboring under the misconception that in order to do
business in California they had to make special "CARB-compliant"
models ("CARB" is "California Air Resources Board", not an
abberviation for "carburetor") and I'm sure that they will be happy to
know that they no longer need to do so due to your impeccable legal
scholarship.

Seen what? Evinrude E-Tec? West is a Mercury dealer, Mercury and
Envinrude are competitors.

Regardlss of the reason, they are banning them, which is contrary to
your contention that they have a specific exemption.

Which has what bearing on the existence or lack of same of laws?

They're already "back in California".

There's nothing difficult about that. Most types of engine that run
on fossil fuels can be made to run fine on hydrogen--some can even be
retrofitted without much difficulty, and for many applications
fuel-cell electric also works fine.

The problems is the development of propulsion systems, it's the
distribution system and handling the transition.

As to where the hydrogen comes from, any technology that can produce
electric power can be used to produce hydrogen.

Maybe to the tune of "you can't roller skate in a buffalo herd"?

Naw, we're talking stink boats<G>.

Here in CA, they were banned when it was discovered they were a major
source of pollution in the water table because of the additives in
gasoline.

Most affected were the smaller applications.

Jet Skis, outboard engines, lawn mowers, etc.

These days, strictly old technology with a finite life span..

SFWIW, trucks used to move containers in/out of the port of LA/Long
Beach harbor have been identified as a major source of particulate
pollution.

Most of these trucks are about a half a step away from the junk yard
since they are usually retired over the road machines, many
approaching a million miles of service.

L/A has simply enacted legislation outlawing vehicles past a certain
age to operate.

The trucker's associations are objecting, but they will lose, it's an
air pollution issue.

Think the first cut was 1989 vehicles.

Penske would never bought Detroit Diesel if they didn't have a new
4-cycle program ready to go.

All the major diesel players have moved to turbo, 14:1 compression
ratio, and electronic fuel rack to comply to the new rags.

It's a whole new ball game.

It becomes a real PITA for a sailboat auxiliary.

I'll have to learn Spanish first.

Most of the cities banning leaf blowers are doing it for noise
abatement, and they do have a point.

Most of those cities affluent enough that any increased lawn service
costs due to not being able to use leaf blowers will get lost in the
wash.

When the guy walks by my window operating his blower, I simply have to
momentarially halt any phone conversations.

As far as the rest of it is concerned, don't expect 2-cycle engines
back in California any time soon.

Now if we could just get focused on a much more difficult problem of
developing propulsion systems that reduce the carbon footprint by
reducing the use of fossil fuels.
