[@timc2219]

a 'stepper' motor is basically a solenoid motor, but doesnt have the losses from reversing the mass of 'pistons' or actuators... just curious as to the 'why' :) for a proof of concept thing, think it woulda been easier to have adjacent coils make the contacts- wouldnt need the rotary cam switch, and contact coulda been axial rather than rotary with the added drag... cool project though

[@garycallahan9307]

Great video! What a great project, and I loved the arcing on the cam tower as well.

[@repalmore]

I love your coil winding method. An engineer I was working with wanted a revolution counter and all kinds of ho ha. Your idea is so simple. I was wondering, could you put the a single cam lobe on the crank with the contacts arranged around the lobe? Keep up the good work.

[@carmelpule6954]

Robert Palmore That is a very good idea, apart from the fact that because the lobe is travelling at a high speed it will hit the contacts and high speed and it will cause them to spring or vibrate too much and due to metal fatigue they will probably be destroyed too quickly, This is why the make and break on the old cars had cams of a small diameter.

[@repalmore]

The gear ratio on the cam drive is 1:1. If the cam was mounted on the crank, it would revolve at the same speed it is now. Spring back and metal fatigue would be overcome by material selection and shape design. Yes, modern vehicles do have larger cams but this is for performance rather than durability (within limits of course). A larger diameter cam allows for faster lobe profiles allowing valves to open and close a little quicker. The surface speed is greater the larger the diameter. Even though the RPM are precisely the same, surface speed increases with diameter. Smaller cams have slower surface speed for a given RPM but do not allow for faster profiles limiting the speed of opening and closing the valves. So it boils down to at this point which engineering challenges do you wish to take on. Not the either one is that much better than the other. Best of luck.

[@heavycurrent7462]

@@8bitslime Absolutely wrong. With those inefficiencies, this configuration allows the perfect alignment of copper wires with magnets. This produces greater torque than a regular BLDC motor, WITH THE SAME AMOUNT OF COPPER AND MAGNET. Doing so, without iron cores too. That‘s why experiments are still going on on this type of configuration, since it weigh less and gives out greater torque.

+stereopolice First off, solenoid motors do not increase in torque as you overload them. Second, they have to be started by an external means. Guys, it has been figured out a long time ago that a rotor spinning inside a magnetic field is the superior way to build an electric motor instead using retarded solenoids..... It's been proven LONG ago that this is the best way. You get more torque as you overload the motor and the motor starts up when power is applied without the need for an external starter mechanism....

[@stereopolice]

+EETechs Yeah, the technology is so awesome, you'll find this motor on not a single airplane, ship, car, or spacecraft. It's been relegated to guys building tiny models to say gee wiz, listen to it click. Nah, I'll stick with the gas turbine as my engine of choice; or the turbo diesel, depending on the application.

You have built an electric motor not an engine. If you do this again; use the magnetic wire tables to design your solenoids. All the physics was done in the last century. Will save you a lot of design time. One thing is when you used copper pipe as the coil armature you reduced the coil efficiency. When you energize a coil it generates a induced field in the pipe which in part counters the coils magnetic field. Put a large diode on each coil. This will block the counter emf when the coils field collapse. May reduce the large sparkles.

+Collegiate Match Fishing The point is that there is not necessarily any practical application. It's an _exercise_ in applying different principles to an old machine to see what would happen. For example, I've seen another version of electric radial motor that has DC motors in place of the solenoids, all driving a large bevel gear. There is little logic in doing that, other than to see if it can be done. If it's a mechanical project, using solenoids makes it classroom-friendly as here's little noise and no exhaust.

[@No1sonuk]

+Collegiate Match Fishing I've actually just thought of a practical application: Simulating a steam engine on a model. Use solenoids in place of the pistons, and you can have an electric-powered "steam engine". Particularly useful for model boats, where the battery could be fitted into a fake boiler and be far safer than live steam.

ThreeDriv3rs Yeah maybe.

[@SamFisherK]

Hippy Lemonz but electro engines is already on the cars... but I dont like that it doesn't have a good engine sound and there are no gears to switch

[@HaloPwNnCrab]

ThreeDriv3rs I don't particular like that either but if they are going to add them, it better be for an actual purpose.

[@Macjohn1419]

Wow! You guys took off on my idea long ago. However, my idea was for 4 or 6 cylinder reciprocating engine built around a cam shaft and designed like an internal combustion engine and it would also produce pressure and vacuum in the cylinders with valves. Great job.

[@pl6867]

This is a 'motor'. Not an 'engine'.

[@E9X330]

Uhhhh what

[@pl6867]

This is not a "radial solenoid engine". It could be a radial solenoid motor, however, if people actual knew what they're talking about. There is good reason that 'rocket', 'jet', 'gas', 'diesel' and 'steam' ENGINES are actually called ENGINES. Not "motors". In a nut shell, 'motors' convert ACTUAL Power into motion, thus the name, 'motor'. Electricity is ACTUAL power, that's also why they call them 'Power Companies', and not 'Engine companies', which consume FUEL to produce motion. Engines convert POTENTIAL power, AKA FUEL, thus Fuel companies, into motion or heat. That's why they call it a Jet engine, or Rocket engine, and so on.

[@E9X330]

Paul List and thats why motorbikes are actually called enginebikes Oh wait

[@bait28]

dicyonary definition, motor and engine are interchangeable

[@pl6867]

Interchangeable as species and genus at best. Sure, 'Man' is 'Animal' but Animal does not define Man as such. Motor is Genus, Engine is Species. You can use Motor for nearly anything that moves, including Engines, but you can't properly do so with the term Engine. They are not conversely related. Motor converts Energy into motion, while Engine uses Fuel to produce Energy to produce motion. So while many do interchange Motor and Engine freely in conversation, they are as wrong as to freely interchange Energy and Fuel. 'Motor' from the Latin: Motum, to move 'Engine' from the Latin: Ingenium, to create or make. This is an electric Radial Solenoid Motor, because electricity is ENERGY, not FUEL.

Brilliant work. Absolutely enjoyed watching this. Very well done. Thank you very much for this.

[@digranni128]

more loss of time 😞

[@YOAWCo]

Love the spark coming off the cams

[@pologamero2648]

Really love the sound. Its like old WWI engines

[@chrisofnottingham]

A really interesting idea, and I like how you have use a cam and mechanical contacts rather than a whole bunch of sensors and silicon.

[@johnthrelfall5]

Great project! Well documented with the video. Good comments from viewers. This video clearly demonstrates some of the basic principles of radial engines.

[@rickautry2759]

You REALLY are needing capacitors across those points. No more pretty blue sparks, but the contacts will last a lot longer that way, and it'd push the efficiency up a notch. Beautiful machine work, and I was happy to see you wind your own coils instead of dropping another 50 bucks at RS for third-rate parts. Very cool.

[@jimbass7867]

Very nice job with limited tools. You give me inspiration.

[@davewhitegas2415]

Excellent work. It goes to show what a person can do with determination toward an end goal. Keep up the good work and God bless.

[@manuelcoronado3633]

Estimado Tonella he visto todos tus videos y te felicito sinceramente he sacado probecho de tu experiencia mediante tus videos mil gracias ,por tus sugerencias practicas, seguire valiendome de tu conocimientos,,,,,, saludos, desde monterrey nuevo león mex.....

[@steinie44]

Very nice job. Did you put diodes across the brushes? They cut down the arcing produced by counter emf.

[@DualDesertEagle]

To me, videos like this prove that most of an engine's noise is created by the mechanics. Even tho the combustions are louder they only make up a small portion of the whole sound.

[@jboshoff4048]

+REALDualDesertEagle remember this thing is unlubricated. Lube would make it more silent.

[@maxcurrent485]

Maybe, but maybe not as there is a shot of some 3in1 machine oil in there if you watch carefully. Graphite might be best on some of it though. It won't pick up dust and dirt like oil.

[@mabblers]

Great job friend. Excellent work!!!

[@fredfarnackle5455]

Very good job! Well done. Lots of ingenuity and hard work - and it works!

[@oxenforde]

That is silly, whimsical, and wonderful.
