CNC Milling Machine for Drilling Drive Control Circuits

Motor driver board for CNC Machine L297, L298 author conducted with integrated 3 axis control circuit for each engine used. LPT parallel port that communicates with the computer is done via the ULN2803 circuit and built on PC849 opto...

For controlling the motors I’m using a chopper controller that works with L297 and L298 ic. The components therefor I’m going to pick up a few control print I received (see below). Rik The reason that I do not use print as they are is because if you adhere to a stepper motor that immediately begins to turn and the steering is not really universal.

Handmade Coil Transformer Winding Machine
Once so I thought was an issue SMPS transformer to wrap a simple mechanism how the board would say they engaged in this business to the machines spinning wheel trying to do was hard :) get ready for some research I did after my curiosity went past a few documents at the scene of As I wanted to share, maybe the winder who want to make our readers who may be knows, maybe I can do it :)
Top of assembly. The base timber is a piece of laminated plywood. Angles are two pieces of junk (they were a tower, are galvanized to fire). drive shafts are printer, easily findable in any junk computer that fixes printers. The good thing is that these axles are steel, but it is not a very hard steel. Can you easily work with it.

DC DC Abwärtswandlerschaltung 600W 60V Eingang zu 12V 50A Die Eingangsspannung des 600 W DC DC Buck Converter-Schaltkreises beträgt 35V ... 60V DC. Ausgang 12V 50A LM5116 für die Steuerung des DC DC Buck Converter ist in der Lage zu verwenden Einstellbare Betriebsfrequenz von 50 kHz bis 1 MHz verfügbar Stromgrenze, Soft-Start usw. Es hat eine Menge Funktionen. Die Ausgangsleistung der 12 V 600 W 50 A DCDC Converter-Schaltung ist sehr hoch, diese Leistung kann durch die Kombination von zwei Einheiten des gleichen LM5116-Synchronbetriebs bereitgestellt werden. LMC555C LMC7101 integrierte Schaltung. Mit Volllast (25a-50a) und Kurzschluss, Hitzetest mit 35V, 48V, 60V Eingangsspannung. PCB-Design der DC-DC-Konverter-Schaltung PCB Größe ist sehr klein im Vergleich zu SMD-Materialien, ist es möglich, dicker dünn von den Nubes zu machen und die Verpackung mit Kupferbändern zu machen. Wirkungsgrad der BSC123N08NS3 und BSC047N08NS3 Die Kühlung der MOSFETs erfolgt wahrscheinlich auf der Platine und der Lüfter oder der Kühler wird installiert. Es gibt detaillierte Zeichnung (ing.) PCB-Zeichnung und Gerber-Dateien
