| Often, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter approach works well, it generates heat and hence wastes power. This simple pulse width modulation DC motor control eliminates these problems. It controls the motor speed by driving the motor with short pulses. These pulses vary in duration to change the speed of the motor. The longer the pulses, the faster the motor turns, and vice versa. |

| I have a small gas turbine turning a 28 volt generator/350 amps. I would like to use this to power a DC motor with some kind of speed control that I could install on a go-cart or other small vehicle. Does anyone have any suggestions or help? Thank you, Bruce | ||
| Can anyone tell me using (appropriate terminology) how a microcontroller could be used to control the speed of a dc motor? Please would be very helpful as i have my exams coming up soon and i do not want to fail Technological studies. | ||
| -.- this is all baby stuff, anyone help me design an effective H bridge pulsed motor control for a 140 amp / 24v 4hp motor? Must be able to sync 2 together for 2 motors (forward and reverse). | ||
| i m doing a project with using a 7.2V batery and i need a 3amp motor driver. can anyone help me figure out how the motor driver should built? | ||
| I have a golf buggy with 2 motors driven from separate smit triggers but a common oscillator, one motor runs faster than the other. Is there something I can do to slow one down easily. | ||
| The circuit can be better if the MOSFET is replaced to higher current ratings, maybe 30A or 50A. | ||
| hey, if you are looking for a pwm dc motor control. you can find it at. www.circuitspecialists.com look for kits. it works a lot like this one works. | ||
| There are enough PWM circuits around the internet based on the 555 for anyones handy use. Size the output transistor ( ideally a power FET ) for whatever you are driving, and limit the supply to the 55 to about 15vd max, Its not too particular about it's supply being ' well regulated' the whole point of it's design! | ||
| I, am pursuing a project regarding speed control of DC Motor using PWM technique. We have been told to do the needful circuit using 555 Timer. Can you please help me out ?? | ||
| i need a pwm switch to control my hho cell i need to feed it with some where between 5 to 15 amps . is there away it can be built to take care what i want (Editor's notes: Good luck with that: http://www.aaroncake.net/forum/topic.asp?TOPIC_ID=7606) |
