I am planning on buying this. ampmodel.com
supposedly is uses PMW. I plan on feeding it 12 volts to make the PMW. now My main question is about PMW its self.
can PMW be used to power any type of electronics? is there any type of electronics PMW will break?
I'm assuming you mean PWM.
What were you thinking of powering?
Many devices don't like being turned on and off hundreds or thousands of times a second.
LEDs don't mind, neither do simple DC motors.

It's a voltage regulator. Switching regulators using pulse width modulation to regulate their output. However, that doesn't look like a switching regulator to me. It looks like a linear regulator, which generally aren't PWM-based.

That's a BEC: Battery Eliminator Circuit. You hook it to the battery of your radio controlled car/plane/boat to provide regulated 5V for the radio receiver. It has no control input. The output is always 5V DC.
Often the BEC is included as part of the ESC (Electronic Speed Control). The ESC takes pulse-width signals from the radio receiver and controls the speed and direction of an electric motor.
Are you sure you don't want an ESC instead?
I have a robot with a 12 volts battery, I'm trying to power all the 5 volts devices because the Ardunio cant handle all of it (servos,PING,Infrared Sensors,LED's Compass Chip,relays ,ect )
"Linear BEC" is either a typo, or the seller doesn't know what that means. That is a Switching BEC. The clues are the 'lm2596' switching regulator in the picture, the inductor in the other picture, the high voltage input range up to 30v (linear BECs do NOT like high voltage), the high amperage output. That said, unless I'm reading the wrong datasheet for that chip, I would not try to pull more than 3 amps out of it. It sounds like exactly what you need though and at a good price.

So "PMW" has nothing to do with PWM? What do you mean by PMW?
Yes, this will work just fine at powering several servos and assorted other 5V devices.
Nope, its definitely a switching regulator - its handling 25W on a tiny board dominated by caps and an inductor! You can even read the chip's part number, LM3596S,
LM2596
SIMPLE SWITCHER® Power Converter 150 kHz
3A Step-Down Voltage Regulator
General Description
The LM2596 series of regulators are monolithic integrated
circuits that provide all the active functions for a step-down
(buck) switching regulator, capable of driving a 3A load with
excellent line and load regulation. These devices are available
in fixed output voltages of 3.3V, 5V, 12V, and an adjustable
output version.
They are naughty to claim 5A output, its rated for 3A, 4.5A peak.
