PWM DC Motor Driver

As the title "PWM DC Motor Driver with Forward / Reverse and Breaking" this series is a PWM DC motor controller that can control DC motors with clockwise rotation and counter-clockwise and is equipped with a braking system. In a series DC motor control PWM DC Motor Driver with Forward / Reverse and Breaking use this system for SASL PWM DC motor rotation speed. Power driver in a series DC motor PWM DC Motor Driver with Forward / Reverse and Breaking uses mosfet IRF150. Then, to control the direction of rotation of DC motor in the circuit of PWM DC Motor Driver with Forward / Reverse and Breaking uses relays. Then the braking system on a series of PWM DC Motor Driver with Forward / Reverse and Breaking is done by a resistor that is connected to the motor using relays.

555 basic PWM controller

IC Timer 555 has a basic PWM controller with features pengendalianlebar 0 .. 100% pulse that is controlled using the R1, at the time of controlling the oscillator frequency relatively stabi so it may be used to build the Simple PWM controller. Frequency of Simple PWM controller 555 depending on the value of R1 and C1, values ​​shown R1 and C1 will form the output with a frequency of 170 to 200 Hz. Diode-diode used in the Simple PWM controller With this 555 can use a 1N4148.

R2, R3 and C3 form a giver triger circuit beginning at the reset IC 555 for 2 seconds. If you want to use a series of Simple PWM controller 555 with the V + not +12 V, it does not matter to raise tilapia R2 where (V + * R2) / (R2 + R3) is about 2, because it limits the signal level reset is 0.5 .. 1V. If you do not do that, then signal the kickstart to get too close to the limit reset signal reception.

Q output of 555 on the Simple PWM controller circuit 555 is used for driver PWM pulse, so that the discharge pin is used for transistor output driver instead. This is an open collector output, and is used as an active signal is low, so it can work. D3 protects the output transistor of the load induction. You may replace any suitable transistors for Q1, BD140 is 1.5 amps.

C4 and C5 is the power decoupling capacitor for the IC 555 on the Simple PWM controller circuit 555, which produce relatively large level of push-pull output stage.

PWM Motor Controller With Forward And Reverse

PWM Motor Controller With Forward And Reverse is circuit controllers for DC motors controlled by PWM technique . The series PWM Motor Controller With Forward And Reverse It can control the DC motor rotation direction. Speed ​​control by PWM technique through MOSFETs Q1 IRF150. Then to play with the directional control relay which is controlled by Q10 using control signals in logic 0 and 1. The series PWM Motor Controller With Forward And Reverse It requires 12 VDC supply voltage.

The series PWM Motor Controller With Forward And Reverse the above can be used to control large DC motor with maximum current consumption 10A. For further details can be viewed directly from the image above circuit.
