|Home > Circuits > Other > Pulse Width Modulation DC Motor Control|
|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.|

|7400 TTl will also I think.|
|4011 for an oscillator??? The 4093 is much better with one Schmitt trigger on each input. Try and see...|
|I am looking for a 24vdc 25amp pulsed dc controller capable of 700KHZ. Is there anything out there like this?|
|I've seen Pulse Width Modulation circuits that use the 555 chip. Is it possible to use those circuits with multiple N-FET to control a 70 amp motor?|
|I have a fishing troaling motor. I would like to control the speed of the motor. Its operating voltage is 12 to 24 VDC. Will this PWM control work ? If not---can anything be done to make it work ? Thanks !|
|i'm making a coyote decoy, and want to put a decoy on a motor and control it with a remote control from a old car, where can i find a reasonable motor to turn appr 8-15 rpm's while using like two d size batteries.|
|i have an elevator final year project , and i want to select a dc motor. but the problem that i dont know how to control it. please can you help me. thanks|
|If 24 VDC 10 AMP motor is brushed motor, you need KDS24050E, if it is brushless motor, you need KBS24051. Kelly controller is good. Their controller improves the perfomance of my motor. You can try it. Their website: newkellycontroller.com|
|What is the best type of controller I can build for my 24 VDC 10 AMP motor? Im really wanting to know a most efficient design. Would it be a PWM integrated into an H-Bridge set up? Thanks all.|
|Definitely needs a freewheeling diode as someone else said. If there is no diode the drain voltage of the mosfet when it turns off will fly up high enough to avalanche the fet and make it run very hot. Diode will improve efficiency quite a lot. Use a schottky type for voltages up to about 50v.|
