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.

DC motor driver with H-Bridge IC L293D

IC H Bridge DC motor driver L298 has two H-Bridge circuit in it, so it can be used to download the drive two DC motors. H Bridge DC motor driver L298 each can deliver currents up to 2A. However, in use, the H Bridge DC motor driver L298 can be used in parallel, so the ability to deliver the H Bridge DC motor driver L298 flow into 4A. The consequences of the installation of H Bridge L298 DC motor driver with the parallel mode, you need 2 pieces Bridge H L298 DC motor driver to control two DC motors using H bridge DC motor driver L298 in parallel mode.

H Bridge Pin IC L298 DC motor driver which is connected in parallel operation mode:
* OUT1 connected to OUT4.
* OUT2 OUT3 linked.
* IN1 is connected to IN4.
* IN2 connected to IN3.
* ENABLE ENABLE A linked to B.

OUT1/OUT4 and OUT2/OUT3 associated with DC motors to be controlled.

Please note that the output of the L298 does not have a safety diode. Thus, the need to add two diodes - flyback diodes, with appropriate current capability, at any point output.

Drive Stepper Motor with IC UCN5804

IC IC UCN5804 is designed specifically for the purpose of stepper motor drivers. Stepper motor driver IC UCN5804 with this very simple and uses only 2 additional components as current-limiting resistors which flows into the stepper motor, it also can be removed so that the stepper motor driver is a pure IC UCN5804 only use only. UCN5804 IC can be used for stepper motor driver with 5-20VDC voltage. Source voltage required for a series of stepper motor driver IC dengn this UCN5804 follow steppernya motor voltage. Picture a series of stepper motor driver ICs with UCN5804 in detail can be seen in the following figure.

Drive Stepper Motor circuit UCN5804

In the series of stepper motor drivers with IC UCN5804 above to run a DC motor takes 2 inputs ie, the input signal and the input logic stepper direction of rotation. The input signal is a pulse stepper with a certain frequency where the frequency of these pulses that determines the speed of stepper motor puter. Then the input logic is a stepper motor rotating direction input logic 0 and 1 that is given to the IC UCN5804 to adjust the stepper motor rotating direction.

Variable Speed ​​DC Motor Controller 12V

For more details can be seen from a series of Variable Speed ​​DC Motor Controller 12V follows.

Series Variable Speed ​​DC Motor Controller 12V This is one series that can be used to regulate speed DC12V motor with PWM technique. Series Variable Speed ​​DC Motor Controller 12V uses a 555 timer IC as a PWM pulse generator to regulate the motor speed DC12 Volt. DC motor speed control process performed by adjusting the potentiometer R1 lever which in principle is set High and Low pulse width of the PWM pulse.

Series Variable Speed ​​DC Motor Controller 12V above the power MOSFET drivers in the form of a IRFZ46N is directly associated with DC motors. Working voltage of this circuit can be adjusted according to needs-driven DC motor, this circuit can work from 3-18VDC.
