The modern mechanic switches are improved concerning of old technology. We need however many times to replacement some old switch or to check currents bigger than the durability of certain switches or simple we need something with modern appearance. For he and different reasons is essential the up circuit. He is simple in the manufacture and the materials that use they exist everywhere. This based in the known 555, which drives a relay of which the contacts play the role of switch. The metal surfaces can have what form we want, but it should they are clean and near in the circuit. In order to it changes situation it suffices touch soft somebody from the two plates. Plate JF1 in order to the contacts of RL1 close [ON] or plate JF2 in order to the contacts of RL1 open [OFF]. The current that RL1 will check depended from his contacts. The Led D2 turns on when the switch they are in place ON and the contacts of RL1 closed.

The UDN2540B is a quad darlington power driver, manufactured by Allegro. Each output can sink up to 1.8A continuous. The typical applications include print heads, relays, solenoids, and stepping motors. It is a replacement for L6221A.

In this design we use two UDN2540B to drive two stepping motors at the same speed. Each motor can be independently controlled. The S1, S2 switches control the ON/OFF and the moving direction of Motor1. The S3, S4 control the Motor2, respectively.

The U1 MC14490 is a hex contact bounce eliminator, it uses to de-bounce the switches and the clock for operation of the chip can also be used to driver the motor phase generator circuit.

The U2 and U3 (74LS74) generate the necessary clock pulse to drive the motors, the U4 and U5 (74LS157) select the phase direction.

This control circuit is ideal for the accurate control of DC motors as well as other applications like lighting levels and small heaters etc. The circuit converts a DC voltage into series of pulses, such that the pulse duration is directly proportion to the value of the DC voltage. The great advantage of such a circuit is that almost no power is lost in the control circuit.

This circuit protects against overload and short circuit, PWM range can be adjusted from 0-100%, PWM frequency is 100HZ-5KHZ adjustable. Operation voltage from +8V~ 35V, minimum current consumption is about 35mA. Maximum current can go up to 6.5A. Efficiency better than 90% at full load.

The functions of three trim pots are as follow:

VR1: setting the minimum output voltage
VR3: setting the maximum output voltage
VR2: setting the output frequency.

The L6203 is a DMOS full bridge driver, which can handle the high peak current up to 5A and supply voltage up to 48V with RDS (ON) of just 0.3 ohm. The chip can run the motor at 4A continuous with proper heat sinking.

The above DC motor driver circuit is implemented with L6203 chip accompanied by a L6205 current controller. The current controller is used in this circuit as a pair of latching comparators. When the current through the motor reaches a level of approximately 1.57A (set by R7 and RCool, the IC U1 (L6506) starts turning off and on the U2 (L6203) at 20KHZ to keep the current below 1.57A. This is similar to fixed off time PWM drive. If the motor stall, the current goes above the 2.0A (set by R9 and R10) then the second comparator channel will toggle the enable line of U2 to actually disable the driver, this limiter will also turn on and off at a frequency of 20KHZ. In case the motor is continuously stalled then when the F1 PTC reset-able fuse reaches it cutoff temperature, it will then turn off the current to the motor to protect the chip from blowing out. With a 20KHZ chopping rate the maximum average running current is very close to 1.5A. It is suitable to most robotic or other applications using the medium size motor.

PWM DC Motor Speed Control Electronic Circuit

Circuit Description
This is a circuit for controlling the speed of small DC motors, it works nicely as a speed controller for an HO or N gauge model railroad.

Theory
The left half of the 556 dual timer IC is used as a fixed frequency square wave oscillator. The oscillator signal is fed into the right half of the 556 which is configured as a variable pulse width one-shot monostable multivibrator (pulse stretcher). The output of the one-shot is a variable width square wave pulse, the pulse width is set with the speed control pot on the control voltage input. The variable width output pulse switches the IRF521 MOSFET transistor on and off. The MOSFET amplifies the current of this signal so that it is powerful enough to control a small DC motor. The 311 comparator is used to cut off the one-shot via the reset pin when the control voltage is below a certain threshold, the 311 is also controlled by the speed control pot. The cut off circuit is necessary because the 556 one-shot circuit will always put out a small pulse, even when the control voltage is at zero.

Calibration
Adjust the 10K cutoff pot so that the motor is completely off when the speed pot is fully counter clockwise.

Use
Connect a source of 12V DC power to the DC power input, connect a DC motor to the DC motor output. Adjust the speed control for the desired motor speed.

Simple DC motor PWM speed control
Circuit Explaination:
The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, notice the diode) is constant and equal to 22Kohm (givin a frequency of about 1Khz, notice the hum).

When the potentiomenter is all up, the Rcharge resistance is 1,0 Kohm (the diode prevents the capacitor to charge through the second potentiometer section and the other 1,0 Kohm resistor) , and Rdischarge is 21 Kohm, giving a 5% on duty cycle and a 1Khz frequency.

When the potentiomenter is all down, the Rcharge resistance is 21,0 Kohm (the diode prevents the capacitor to charge through the second potentiometer section and the other 1,0 Kohm resistor) , and Rdischarge is 1 Kohm, giving a 95% on duty cycle and a 1Khz frequency.

When the potentiomenter is at 50% , the Rcharge resistance is 11,0 Kohm (the diode prevents the capacitor to charge through the second potentiometer section and the other 1,0 Kohm resistor) , and Rdischarge is 11 Kohm, giving a 50% on duty cycle and a 1Khz frequency.

The 555 provide good current capability to drive the mosfet fast and to drive a bipolar transistor.

I actually use this system to drive the DC motor of my small Rotary spark gap Tesla coil at variable speed

If you are disgusted by the 1Khz hum of the motor try to rise the frequency out of the audible range (replacing the potenziometer), but rembember that at higher frequency inductive reactance of motor rises so the the efficiency would drop.

Important:
Obviously the mosfet (or bipolar) must have enough current capability to drive the motor, so the drain (or collector) current must be equal to maximum motor current (at power supply voltage, when it is blocked). The snubber diode too, because it shorts the motor on the off cycle. Both mosfet (or bipolar) and diode have to be hooked (if you don't want them cooked Wink ) to a heatsink
if the max motor current is more than 100 or 200mA. I suggest to not stress to much the motor with too much work because it overheats both motor, transistor and diode.

If you don't want braking in the off cycle just place a resistor in series with the snubber diode, it should rise a bit efficiency but have more inertia when slowing the motor down. The value of the resistor must be R=V(breakdown transistor) / Imax, and the power should be 5W. Mosfets have internal zener diode, but don't count on it

555 Timer Pwm 12Volt 50Watt Motor Lamba kontrol

A Simple PWM Circuit Based on the 555 Timer
One of the most fundamental problems in robotics is DC motor speed control. The most common method of speed control is PWM or pulse width modulation. Pulse width modulation is the process of switching the power to a device on and off at a given frequency, with varying on and off times. These on and off times are referred to as "duty cycle". The diagram below shows the waveforms of 10%, 50%, and 90% duty cycle signals.

PWM D.C. motor drive Low loss speed control By 4093
Introduction

This circuit is a very compact switching regulator for small DC motors. I use it for my small printed circuit board drill
(18 Volt, 1.5 Amp), but it is suitable for many other applications (e.g. 12V DC halogen dimmer).

Circuit description

R1, R2, C1, D1, D2 and schmitt trigger IC1B build a 1kHz oscillator with adjustable duty cycle.
The output of the oscillator passes through buffer IC1B/C/D which drives power mosfet T1.

When T1 is switched on, a current will flow from the +Vmotor supply via the motor and T1.

When T1 is switched off, the motor current is interrupted; because the motor acts as an inductor,
it will try to maintain its current, which can flow through freewheel diode D3.

The avarage current through the motor depends on the duty cycle of the oscillator.

The circuit losses are very low, for my 1.5 Amp drill, no heatsink is required for T1.

PWM Motor Speed Controller - DC Light Dimmer by IC LM324

Introduction

A pulse width modulator (PWM) is a device that may be used as an efficient light dimmer or DC motor speed controller. The circuit described here is for a general purpose device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or 24 Volt systems with only a few minor wiring changes. This device has been used to control the brightness of an automotive tail lamp and as a motor speed control for small DC fans of the type used in computer power supplies. A PWM circuit works by making a square wave with a variable on-to-off ratio, the average on time may be varied from 0 to 100 percent. In this manner, a variable amount of power is transferred to the load. The main advantage of a PWM circuit over a resistive power controller is the efficiency, at a 50% level, the PWM will use about 50% of full power, almost all of which is transferred to the load, a resistive controller at 50% load power would consume about 71% of full power, 50% of the power goes to the load and the other 21% is wasted heating the series resistor. Load efficiency is almost always a critical factor in solar powered and other alternative energy systems.

One additional advantage of pulse width modulation is that the pulses reach the full supply voltage and will produce more torque in a motor by being able to overcome the internal motor resistances more easily. Finally, in a PWM circuit, common small potentiometers may be used to control a wide variety of loads whereas large and expensive high power variable resistors are needed for resistive controllers.

The main Disadvantages of PWM circuits are the added complexity and the possibility of generating radio frequency interference (RFI). RFI may be minimized by locating the controller near the load, using short leads, and in some cases, using additional filtering on the power supply leads. This circuit has some RFI bypassing and produced minimal interference with an AM radio that was located under a foot away. If additional filtering is needed, a car radio line choke may be placed in series with the DC power input, be sure not to exceed the current rating of the choke. The majority of the RFI will come from the high current path involving the power source, the load, and the switching FET, Q1.

PWM motor speed controller
Description.
This circuit is designed as per a request made by Mr Vinoth from India. His requirement was a 12V/5A DC fan motor controller. I think this circuit is sufficient for this purpose. Quad 2 input Schmitt trigger IC CD4093 is the heart of this circuit. Out of the four Schmitt triggers inside the 4093, U1a is wired as an oscillator with adjustable duty cycle. The U1b, U1c, U1d buffers the output of the oscillator to drive the switching MOSFET Q1.The MOSFET drives the DC motor according to the switching pulse obtained from the oscillator. When R1 is varied the duty cycle varies and so do the speed of the motor. Diode D3 acts as a freewheeling diode.

Some Power PWM Drivers For Electric DC Motors

1. Warning!
The author makes no warranties that this document is free of errors! Be very careful if connecting these circuits to larger lead accumulators! Very high short circuit currents could be dangerous and destroy and burn your circuits! It is highly recommended to first test the circuits with a current limited power supply and a small motor!

2. Introduction
PWM (Pulse Width Modulation) is an efficient way to vary the speed and power of electric DC motors. Here two drivers are described for 24 V (15 V to 30 V) motors with a maximum current up to 80 A. These drivers can for example be used to vary the speed of small electric vehicles. The first driver use a power PROFET transistor switched at 500 Hz and the second use a power MOSFET transistor switched at 20 kHz. The second method is preferred due to its higher frequency.

Speed Controllers
V3.03 5-Oct-2005
1. Introduction
The purpose of a motor speed controller is to take a signal representing the demanded speed, and to drive a motor at that speed. The controller may or may not actually measure the speed of the motor. If it does, it is called a Feedback Speed Controller or Closed Loop Speed Controller, if not it is called an Open Loop Speed Controller. Feedback speed control is better, but more complicated, and may not be required for a simple robot design.
Motors come in a variety of forms, and the speed controller's motor drive output will be different dependent on these forms. The speed controller presented here is designed to drive a simple cheap starter motor from a car, which can be purchased from any scrap yard. These motors are generally series wound, which means to reverse them, they must be altered slightly, (see the section on motors).

Below is a simple block diagram of the speed controller. We'll go through the important parts block by block in detail.
