Hello, I have a 12V DC motor that draws 300mA. My power supply also Leifert 12V. Now I just want to build a voltage mollier diagram for steam regulator as possible, so I then use a potentiometer from 0 - 12V can regulate. Does anyone know how you can fix easily? A diagram would be nice too :) Thanks in advance :) iMoq Thread Starter 44665 Posts: 1 Joined: Saturday 3 December 2011, 07:18 Postal Code: 00000 Country: Germany / Germany E-mail
Hello and welcome to the forum, I would google times for a block as LM 317 and there are GNZ simple circuits in order to accomplish that. Even in the data sheet of component mollier diagram for steam should be able to find such an application. http://www.national.com/mpf/LM/LM317.html # Overview to regulate the desire from scratch, you should, however, give up. It starts so at 1.2 volts. Good luck and have nice weekend Lothar Addendum: or buy for 4 euros in Hong Kong completed: Bay Number: 360 414 755 775

Hello The desire to regulate from zero, you should, however, give up. It starts so at 1.2 volts. Not only that, but the upward direction is reduced, mollier diagram for steam the setting for the "own use" of the controller aka Voltage Drop or dropout voltage. The Linked Data sheet from National Semi they are with about 1.7 V at 200mA load current and at about 25 C. Realistically can also 2V or more depending on China supplier of LM317 (CDIL) and the load occur. So has the LM317 variant only an adjustment range of 1.2V to ca.10V. If it must be a linear regulator, the pin-compatible low-drop LM1086 would offer. What which argues against mollier diagram for steam a simple PWM, just because it comes to an engine? PWM provides higher torque at low speeds and in the lower setting mollier diagram for steam produces much less power dissipation than the variant with linear regulators, which would mean in battery operation much longer running times. After http://www.circuitlake.com/simple-pwm-c ... c-555.html is the fit not much more effort than a component LM317 with the necessary mollier diagram for steam protective circuit, instead of transistor Q1 and a low-loss MOSFET as BUZ11 or BUZ72. The "Bay" article has links to the Erfinderlein will probably contain such a PWM solution. Only because it was primarily designed for LED, is the question mollier diagram for steam whether there also necessary in Inductive load protection measures such as free-wheeling diode were used. The then must be externally yet retrofitted if necessary. mfg Leonard 44682

Also does not sound like an industrial application. I have understood that the questioner just love wants to change times with the potentiometer the speed. At best, inserted as a small DC-tool behind it. In my more than 3000 days of work as a moderator mollier diagram for steam in this forum after, you have to work out the details with such a request, slowly instead to put the questioner mollier diagram for steam equal with PWM on fur. A student who is not has relevant knowledge otherwise so overwhelmed-. A Grandpa as I might, too. So please in the future a bit slower with the horses. Greeting Lothar
