    Hello,

    I have arduino as PWM source signal,
    then I'm searching driver electronic schematic to control a DC motor 130VDC 12Amp.

    I using the powerful google search engine,
    then found a lot samples to driver DC motors 12vdc and 24vdc few amps.
    but not found for DC motor 130vdc 12Amp..

    I have few resources to burn transistors on trial and error,
    then looking a sample tested, functional and safe.

    I suppose many things, but I can not afford failure.
    maybe I need a driver for mosfet / IGBT

    This motor at 100% have 28800 RPM.

    I need control from 0 to 100% with powerful arduino pwm.

    I appreciate any related information.

    If you want to control using a simple approach without the need for a DC power supply per-se, is to use a descrete diode bridge with two of the rectifiers being SCR's this is very effective for full wave phase angle control.
    Another simple method is to use a full wave bridge, but place a phase angle controlled TRIAC before the bridge.
    At that RPM, are you sure the motor is not a Universal type?
    If it were, you could use the TRIAC direct, no bridge needed.

    I appreciate your prompt response.

    They are universal carpenter router motor.

    I need to control this motor with arduino PWM signal.

    I thought I have no electronic schematic
    about connecting PWM to SCR's.

    On a previous occasion I failed miserably,
    trying: controlling triac with pwm signal.

    With MOC3010 turn on/off as relay,
    I need more control as PWM signal.

    that is, for a suitable driver for the voltage and amperage.

    The would most certainly be a Universal motor (AC/DC).
    You may find it difficult to control down to a low RPM, however.
    With a Universal motor, to get accurate control, you most certainly will required a feedback of some kind such as a simple tach.
    There is a poster here, The_RB that I believe markets his design of one of these type of controls.
    SuperPID.

    Yes, I see this as proper, maybe perfect.
    But, I have no $ 131.75 for this.

    I need something like this example, which attached.
    perhaps with driver for mosfet,
    which driver mosfet and which mosfet driver use?

    I need an example.

    Also I would like to know more about what you say:
    "You may find it difficult to control down to a low RPM"

    ...you could explain to me*something about this?

    This type of motor is a series connected motor, Field in series with the armature, this type of motor normally operates in a run-away condition whose rpm is essentially limited by any load, windage or friction at the applied voltage.
    Like I mentioned, you are most certainly going to need feedback of some kind for precise control under load etc.
    One of the problems comes from the frequency of the tach, if a single pulse, at 28800rpm the frequency of the pulse would need to be monitored be every 2ms.
    At 100rpm the rpm would be only updated every 600ms.
    If using a DC supply with PWM control you may be able to get better control than possible with Phase angle control?

    I understand minimum PWM Base frequency close to 1 kHz.
    I want to live that experience. How I can do?

    I am interested in the phase control using pwm.
    I wish some examples, too.

    I'm lost in the desert (figuratively).

    By PWM control I assume you mean the control signal not the DC power technology?
    One paper on phase angle control is Fairchild AN-3006 and some Pic Micro app notes, AN-521 etc.

    I found this.
    http://www.ebay.com/itm/12V-24V-48V...345?pt=LH_DefaultDomain_0&hash=item53ff405f49

    I would like to know how it works.
    This is phase control? ...with DC or AC?

    This is a Chinese hoax does not work? ... or work fine?

    These typically use a 555 with a pot to control the output of a PWM power supply with single power Mosfet to vary the speed, very simple but also very little in the way of features.

    Then I need a schematic of this, but without 555 (PWM external).
    You can help to me with this?
