Alternative motor windings and drive schemes

[Clugh]

Chris, weißt du noch, als ich dem Typen aus Dresden sagte, er solle A-Serien-Magnete für einen 5025 nehmen, sie mischen und axial stapeln? Man braucht ein Verhältnis von 7/8, genau wie Dr. Gerlings ungleichmäßige Windungen zählen, wenn man den Schlitz teilt. Er hört nicht zu und hat das Material zur Hand, also weiß ich nicht, was man mit ihm machen kann. Er ist wirklich nicht daran interessiert, mehr mit dem Scorpio zu machen. Obwohl sie bereits für das gesamte Rohmaterial bezahlen, um das herzustellen, was sie bereits herstellen. Eine verschwendete Spielzeugkiste. Oder vielleicht ist er mit Reparaturen überlastet.

Es würde ohne Modifikationen auf den 5050 passen

Ich weiß nicht wirklich, was er so Besonderes für Scorpion getan hat, da das Testen extrem einfach gewesen wäre, da sie einen Leistungsprüfstand haben.

[Clugh]

Übrigens kann das Alphaeisen möglicherweise nicht mit dem EDM geschnitten werden, da es nicht leitfähig ist. Sie müssen es also möglicherweise mit einem Wasserstrahl schneiden oder fräsen.

I contacted VAC myself. The Talking on the German social media doesn't mean anything to US....

Danke

The enamel stripper was a solid purchase. I use it alot and it works well. It is very dependable and it does what it is supposed to do!

Integrity is everything. Not ever for a sale or anything else would I jeopardize mine.

As we can see the African engineer from the IEEE's rotor is laminated and segmented with dovetail locking for high speed retention. The optimal SRM rotor will typically have flussperren involved to lower torque ripple and increase static torque output. This is the 12N8P dc excited flux switch. No magnets! to optimize it all the "gimmicks" will apply.

[Clugh]

A laminated rotor in the case of an external SRM should actually look similar to a internal rotor stator with very short arms. Im my mind I know basically what it should look like. If you do research in the hammers you can minimize the noise inherent with SRM. The one I salvaged used and ABC windings system . In the DC flux switch six coils are armature coils like we normally wind LRK and the other six are the dc field coils. In control id imagine with a comparator or op amp you can set hysteresis so the field coils are always optimal to the armature coils .... It is common in industry to use tools like slot wedges to quiet the machine a lower its load amperages. They improve the "sinus" relationships within the power system.

You could ask Kosta about such a control.

Hi Ralph! see the slot wedges and ABC windings...for 220 volts.

Mehr SRM! And the controls. The laminated rotor is right here.👀 easy to show... This one had to be quiet and energy efficient because it was from a house hold appliance made to run all day. The inverter tracks the rotor with photo op and the trigger wheel appears to be set up in grey code which is going to be interpreted to hex or some binary decimal coding that correspond to a position reference data base in the MCU's registry.

Nobody was interested in it when I talked about it on the german social media years ago...



Danke,
Hubert

[Clugh]

Truthfully I could wind the DC excited flux switch machines right here.... I'm already ready with dovetail tooth detail to lock the slot wedges in. All it needs is a turned aluminum can and the end bells for the bearings.

Enjoy the GSM 👁 see itz hell there on every topic.....

Andreas has the right idea.... what a waste of time.

Evolve.....

LOCTITE^® AA 332 is an acrylic-based structural bonder for fast cure at high temperatures. The 2-step, activator-cured adhesive meets requirements for surface permanent magnet (SPM) bonding in electric motors, especially for high speed and temperature resistance in traction control windmills. It has a fixture time of under 3 minutes, a shear strength of 11 N/mm², and a temperature resistance of 180°C (356°F).

• Bonds metal-to-metal including surface permanent magnets (SPM)
• Temperature resistant up to 180°C (356°F)
• Thixotropic for ease of application
• < 3 min fixture time
• 11 N/mm² shear strength

[Clugh]

For now I plan to use a standard rectangular pm in the 50mm external rotor flux barrier machine. That is what is in a Kontronics pyro. They have no arch. U could think about and eazy snake line SmCo later. I have a 650 here with 2 loose magnets so I've had a chance to look at it. Nothing special but they are good and strong. The speed pilots can plan to have a lot of fun against Powercroco in speed events.

Hi Hubert ,
wow you are fast. About the apha iron. Some flywheel store alternator/motor we have designed with it. We seletct the stator in easy to cut parts , most rectangular , that we can easy glue toghether to get a first look alike stator . Next process was to grind the right designe with diamond tools to get a round and right for the flux designed stator. This ar so strong tha it can handle the power and run with very low loss. One reason to go this process was that we canˋt get such big alpha iron parts that have the size.
looking forward with the fluxbarrier design , itˋs great.

The special annealing makes the Durabar machinable. I believe a mini mill can process it. Just need to find the right spindle speeds and feed rates. The workpiece is always flooded with coolant in a real CNC milling station. A 4 axis attachment or a or indexer may help but the water jet can do it but it may still end up being made from several thick laminations. As thick as the jet can cut is cheapest. With VAC I inquired about VACOFLUX which was an alternative to plain silicon steel with 17% Cofe versus Ralph's 49% which is quite pricey for the performance. Hadn't hear back yet. About curie performance Depending on the circuit a SmCo in the same dimension may work since it has a little less energy to saturate the stator as quickly as an N50 Neo but it can survive 300C and continue on with adequate field to commutate. I had a conversation going with BOMA Tec that kind of got left on its ears professionally. They want dimensions but Im not ready to give any. The Flux barriers armature coils will have the iron added that was taken away from the adjacent teeth. I have the Dr's ratios I can extrapolate to a 50mm LRK 12 slot diy cut The thick teeth will be about a 1/3 wider that the adjacent which will be around a third thinner. The hammers on the thick teeth need to cover a pole pitch and the yoke thickness needs to be adjusted. Theres not alot different with it than the uneven tooth width approach. You know from papers Ive sent you what can be done with tooth tips even on a standard cut so it is no need to let Ralph see that. 👀 That's a secret weapon that is traditionally cut. and he's on patrol here...

The Alpha iron is another soft magnetic that shows really great potential as a solid stack at a price point that CoFe simply could not compete. It is well over the head of the silicon saxony boy in Dresden with no degree. Occasionally you will read the blabber mouth blurt out about it on the German social media. Its funny because Ralph Okon and his silly friends truly know nothing about it so the comments never lead anywhere they just highlight how clueless the troop is because not one of them could comment from an iota of experience which is zero .

It is also something THEY cannot get readily in their hands. I have a special local supplier willing to work with me to supply the specially annealed ductile iron.

Chris, die Rotoren des Pyro und Scorpion sehen aus wie kaltgewalzter Stahl. Sie sehen nicht laminiert aus. Ist das richtig?

Danke,
Hubert

[Clugh]

HMM maybe Gerd is getting weary of the conduct which is clearly one sided with the ignorance . Im glad coz Micheal is on it bad. Had even posted YGE is the only choice but holds an APD in hand. Im glad RCU erase the turbine thread behind Ralphs link he left in my thread trolling at the beginning. 😄

Hey Ralph! It looks like Gerd doesn't want to hear about the Christmas ornaments in the Knocker thread!!! Guess you better stop camping here in my thread and get buzy repairing their motors in Germany!

interesting response from the moderator there....doesn't sound to Christ-massie does it?.

WOW!

Look! So you can see....👀

In America we are rebuilding a damaged pyro 650 rotor with loose magnets. In America we glue it with Loctite AA 332 not uhu endfest general construction epoxy or liquid steel like i have seen in some Shadetree repairs. The specifications of the Loctite permanent magnet adhesive is posted in post #2068. The original 650- 83 so it looks like a 10 turn 1.07mm delta at around 850 Kv according to Kontronics It is severely underfilled and the user want its just a notch faster around 880Kv so I have have some room for substantial copper. Around 11 to 12 turns in a YY 17 AWG should bring me in the ballpark which isn't maintained underload anyway. If im not mistaken you may lose 100Kv underload with the Kontronics motor and strands of 17 AWG 1.21mm . at UVW Is what I saw on the empiric bench @ 10 degrees timing on the castle. I don't know where the silicon saxony or Audiotroll gets itz information but a 10 turn delta in 16 AWG should work pretty well also. The AJ runs much slower around 650Kv if I'm not mistaken Id have to look at my notes. Since a pyro uses a rectangular magnet it is a easy candidate for Bomatec to provide a snake line pm. that will lower the load amperages. Whose to say a wire EDM cant post process this as well?? I'd imagine its still structurally fragile as compared to the solid pm. Better use a great adhesive that is going to hold. The F3A pilots all detest the standard steel bearings Power Croco scorpion comes with and Ralph still does not pot the windings with a thermally conductive epoxy that can withstand 180C* The steel bearings rob rpm and raise the temperature and load amperages. They also raise idle current amperages. All these things are additive and only lower efficiency of the machine. Since the steel bearings are not electrically isolated they generate noise and transmit triplen into the motor shaft that further shortens the steel bearings life. They are also not as quiet.

Good News from I care. They are sending the superchief 4 to 1 planetary gearbox. I'm only waiting to see if they can send the 8mm and 6 mm pinions and flange to fit the 600 pyro and also to fit the larger machines on the 30mm bolt circle. The P32 is probably already delivered to my other property. I'm off all week so I plan to get something done.

Thank you for you time and patience,

Das Problem mit ignoranten Leuten wie ihm ist, dass sie nicht erkennen, dass es beim Drehmoment egal ist, wer schwarz oder weiß ist. Um die 41-Pitch-Propeller mit 16.000 U/min zu drehen, ist ein bestimmtes Drehmoment erforderlich, das leicht zu berechnen ist. Powercroco-Motoren haben eine Drehmomentkonstante wie alle anderen. Sie haben auch einen Wicklungsfaktor. Wenn ein Dummkopf das anwenden könnte, könnte er sehr schnell feststellen, ob der Klopfer ausreicht, aber anscheinend ist ein Clan nicht intelligent genug, um diese physikalische Wahrheit zu erkennen. Sie stellen die besten Taschenrechner der Welt in Frage, weil sie sie ständig falsch verwenden. Sogar Gerben hat diese Fehler gesehen.

Die Frage, die Gerd beantworten muss, ist, ob eine Maschine der Ralph 50-Serie mit Direktantrieb 4,23 Nm bei 16.000 U/min liefern kann, im Austausch für 7 kW Verbrauch und 69 Grad Celsius. Ich werde die Katastrophe von Silicon Saxony nicht für Sie berechnen. Ich schlage nur vor, dass seine Freunde seiner alten Signatur folgen und aufhören, die schwarzen Trolle zu füttern.

[Clugh]

A much stronger geometry with a Pyro 1000 over a Knocker 5050. More iron here. You need thicker teeth like these to make torque.

Say cheese!!!
