I have a 24 volt 25 watts 8 amp DC motor. How can I possibly control its speed and direction?

Please help...

Thanks

 

Your best bet is to use a PWM method to control a DC motor. There are a lot of options out there. You can design the circuit yourself using a microcontroller or buy a kit.

 

Thanks for the reply k-young!

I bought this motor driver ( K243) http://secure.oatleyelectronics.com/files/K243notes.pdf ,but I want to replace the potentiometer that controls the direction of the motor (When the potentiometer is centered the motor does not turn....Rotating it clockwise makes the motor turn one way...anticlockwise..the other..).

I want the direction of my motor, to be controlled by my arduino micocontroller. Do you have any idea how?


Hope for your support,

You can buy a digital pot and control it with the Arduino.

 

From the data sheet, it looks like the board will accept standard R/C type signals as inputs. Can't those signals be simulated by your Arduino?

Look at this...... http://www.horrorseek.com/home/halloween/wolfstone/Motors/svoint_RCServos.html#DrivingTheory

 

Thanks for the help guys!

I'm thinking of using a digital pot to be controlled by my arduino microcontroller, but it would be much better if my arduino microcontroller can directly control the direction and speed by sending pulses.

http://secure.oatleyelectronics.com/files/K243notes.pdf ( K343 data sheet):

If I connect the SIG ( k243 motor controller) to the digital pin of my microcontroller and GND ( k243) to the GND pin ( microcontroller) and send pulses, would that possibly work? Can I control the direction and speed of the motor?

Help…

 

Read the item on Page 2 of your data sheet that has the header "1-2mS (Radio Control) INPUT". That should shed some light on the capability of the controller.

Interesting you are asking this question here when 10 years ago you had the same discussion on an Arduino forum.
What has happened in the last 10 years?

That post here was 10 years ago too.
