What size motors do people use and what have they gotten them off of or purchased them from, to make an extractor variable speed and reversible. and I am not talking about using a drill.

i was wondering if a ceiling fan would work, its reversible and variable speed, could probably hook a light dimmer switch on it to have better control of the speed. I have a 9 frame extractor now that is hand crank and not reversible. I bought it from dadant about 10 years ago. and really remember how much hand cranking sucks. and flipping the frames.

When using a ceiling fan, they make a variable speed switch you just wire inline on the plug.

Ceiling fans are reversible.  They have a reversible switch on them.   When you tear out the motor, keep the switch inline with the wiring.

I use a treadmill motor (or at least I will when I get the extractor ready for it). They're powerful, infinitely variable, and free for the taking. How many 1-2 year old treadmills do you see sitting out for the trash?

I think reversible is unnecessary, but variable speed is important so you can start slow while the combs are heavy with honey but crank it up when they are almost dry so you can get the last of it out quickly.

reverse would be good for tangental-basket type-alow basket to swing freely and basket will flop -changeing direction and -which side of frame is on the outside with rotation direction-years ago they made a 8 frame extractor (buy life time i think ) the thing is the size of  a 60 frame radial-antque these days-anyway this machine had this advantage -also they make this type of machine to extract MANUKA honey which is very low in moisture content and hard to extract--spins one way for short time --then spins another way for short time-baskets flop each time direction changes

Ron

You’ve got a 120VAC single phase AC induction motor here.  Fractional HP motors are not typically “capacitor start” but I can’t tell that without a picture of the whole motor.  A capacitor start motor will typically have a cylinder like metal bulge on it, under which the starting capacitor is located.  Assuming no bulge, a Grainer type controller would probably work.

However the one you picked is not the best choice.  The problem is that Grainer controller has a max current rating of 2.5amps, whereas the motor has a current rating of 4.6amps.  This means starting the motor might burn up that Grainer controller.

If you wanted to experiment, a 600watt light dimmer switch from your local hardware store might work as some others have suggested in this post.  A 600 watt dimmer is good to 5amps.  The problem with dimmers is they’re usually designed for resistive loads like light bulbs.  An AC motor is an inductive load that causes some lag in the current and this can mess up the Triac in the dimmer.  

I like Hardwood’s treadmill motor idea myself.  Treadmills use DC motors instead of AC motors.  AC induction motors are designed to run best at a fixed constant RPM.  That is because their speed is a really a function of the AC power line frequency (60Hz) and not the voltage.  When you just cut voltage by using a dimmer, the motor still wants to run at 1725 rpm (in this case).  However with less voltage, the motor makes less torque and it slows down due to the loss of torque.  You get the illusion of speed control because you’re losing torque.  

The DC motor in a treadmill would be a good match here since they have high starting torque and their speed can be controlled without a loss of torque.  You can buy low cost DC motors from places like www.surpluscenter.com for under $40, but they don’t come with a speed controller.  That’s why I really like Hardwoods suggestion!  You can get a free motor AND free speed controller from people adverse to exercise.   As hardwood says, it won’t be long now before they start putting them along side the road!

Nice work, Bee Bop

Thanks for the photos.

Another good performance feature about treadmill DC motors is they have a heavy flywheel attached to the shaft (see Bee Bops photos).  This should help smooth out any speed jitters of the extractor.  That is what inertia is used for.  The only downside is the weight of the flywheel; these can be hefty motors! 

If you don’t have a weight set and want to do some biceps curls, try curling a couple DC treadmill motors!  Especially the ones that are not permanent magnet motors.

Just get ya a good electric motor a hydraulic pump, valve block, flow control valve, hoses, a tank, and a hydraulic motor.  You'll end up spending alot of money but you'll have the only extractor that will do everything you want and never be over loaded.  Hehehe like i always say when in doubt overkill lol.  Not really an option but being a hydraulic man i've often thought about building such a contraption.

Sorry I didn't see this at first.  It won't work.  The control is a for a universal motor like a sewing machine motor.  Universal motors will have brushes and commutator.  You either have to run this single speed or get an inverter drive for it.  I would advise against and inverter drive on a heavy inertial load.  There is such a thing as a soft start which is like a fixed accelerating inverter drive but will come to full speed in about 10 seconds.  These drives are not going to be cheap if they are going to last.

For the hobbyist I would recommend that you do the speed variations with pulley drives and get the soft start with belt tension.

I don’t know Acebird.  Although Ron’s motor looks far older than I am, there is no identifier I see that says it’s a “Universal Motor”.  I stand by my assertion that it is an AC induction motor.  Universal motors do have brushes and commutators as you stated and that means they can run from AC and DC power, hence the term “Universal”.

The name plate on the photo though says “AC Motor” (not “Universal Motor”) and that normally means you’ve got an AC induction motor.  Invented by Tesla in 1892.  They have no brushes and instead rotate by magnetic induction from the stator to the rotor.  Hence they are called AC induction motors.

I think we both agree Ron’s motor isn’t the best motor for an extractor!  However you don’t need an inverter to run one of your universal motors.   The old drills from the 1970s used “universal motors” and controlled the speed via a rheostat.   A dimmer switch (Triac) is a modern day replacement of the old rheostat.  The rheostat worked, but the speed regulation wasn’t real good in those old drills, but it worked.

An inverter is an expensive piece of hardware and is used when you need to implement speed control on a AC induction motor WITHOUT the loss of torque.  This is how most electric cars are powered.

I still think Bee-Bop has the best idea for a home made design!

Bluebee my reply is to the question about the drive control that was selected (to be used on a universal motor)  The motor in the photograph is an AC motor and not a universal motor.

It is possible, I don't know for sure but it would seem to me that having a DC power source they would use DC motors.  Otherwise they have to chop up the DC into AC on the power end.

Sorry Ace, my mistake, I didn’t read your response as closely as I should have.  You did say Universal controller, not motor.

AceBird, you’re right, both AC and DC motors have been used in the past to power cars.  They are both WAY more efficient than an internal combustion engine (if you don’t count the loss of efficiency burning coal to make electricity).  The reason modern electric cars are using AC induction motors is cost and reliability.  AC induction motors are very simple machines and have no brushes to wear out.  They can run trouble free for decades.  You can create DC motors that are brushless too, but the costs of rare earth metals (and IP) for the PM magnets are prohibitive.

The downside to going with a AC induction motor for a car engine is the need for a 3 phase inverter to control the frequency and the voltage amplitude of the power being feed to the motor.  This allows you to control the speed of an AC motor without the loss of torque.  

Ace, are you going to build yourself a home-made extractor at some point?  Sounds like a fun project.

I saw one a couple of months ago that was made from a vacuum cleaner motor, and a dimmer switch.  To make it reversible he simple twisted the belt.  Changing the path of the belt from a circle pattern to a figure eight.

Acebird's comments are worth noting. There are a variety of AC motor types available.  A shaded pole type AC motor requires a capacitor and is not easily made reversable, if at all. Some AC motor require a capacitor to run and others just require one to start.  Be careful before placing an order for one.  Plus torque rating is also worth considering. Some AC motor types have poor starting torque capability.

So I finally got my DC motor and controller, bought a treadmill off craigslist for $25.00 and stripped it. the only thing I have to do now is get a bushing for the pulley that was on the roller and attach it to the handcrank shaft.
