Hello, I am teaching myself electronics. I have been reading for several weeks because anybody can build an elementary circuit that turns on an LED, I just kept reading. Electronics is so fascinating and logical, but my simple brain can only handle so much and at last I have become motivated to build an H-bridge with some parts that I have. This is forcing me to confront several problems that likely have easy solutions. This is where my brain starts to fry, please nudge me in the right direction.
I want to operate a small MOTOR (1-6V operation, 3Vfree run Current, 3V 13000RPM free run speed, 3V 800mA stall current)
[1] The first question that comes to mind is, what metrics here are relevant for selecting complimentary transistors and diodes?
The transistors I have on hand are the S8550 and the S8050 (NPN and PNP) these parts arrived in a kit together so I am hoping they work for this. But I am learning so I don't want to build without understanding. TRANSISTORS are (2W, 5Vbase emitter, 20V collector emitter, 30V collector base.)
SO looking at this I am forced to wonder
[2] What metrics here are relevant to the motor and a 9 volt battery and what is not? You see this is a puzzle and the smoke issuing from my ears is my brain on fire, because it gets more complicated then this when I begin to factor in the inductive load to the diodes? [3] What motor metric offered above do I use to determine the proper diode? The diodes I have are IN4007 with a 1A forward current, 30A non-repetitive peak current, 5uA reverse current and a 1000V peak repetitive current
This in a nutshell is my problem; understanding the relationship between these 3 parts regarding their specs. I think I can solve for if I need a resistor: I am using a 9V battery. [4] I figure Once I have my components sorted out I can add up their voltage and subtract from the 9V battery to get the necessary Ohms for my resister?
