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.

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.

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?
