I need some information on the AT89C52 based DC motor control for the antenne positioner system. Its feedback control circuit to drive the motor . I will be gratful if some useful links can be provided with some circuit diagrams.
What kind of DC motor? Which voltage and current? Just forward and reverse or variable speed from 0 to 100% or any other range?
What type motor it is?... I did BLDC motor controller using PIC Micro... For that I hav used PIC16F873, Hall Effect sensors, MosFET Driver IC & MosFET Bridge... What else u need?.. K.Kumar
For DC motor control. H bridge is one, using PLL thats another option. For switching look up for PWM, but you must be sure to correctly saturate the transistors.
I built a scheme that controls the speed of DC motor through the PC, see the circuit. Everything was fine with power supply of the motor up to 30V. When I applied 200V everything burned. I didn't understand what happened - the two MOSFETs IRFP260N, the MOSFET driver L6384 and the uC are out of order. I didn't apply a load but this couldn't (...)
i am using l6206 for dc motor control and designed my circuit exactly its given in the datasheet of l6206.but i am getting very less current in the output pin though giving full current as input.what's wrong

Hi, i am new to control systems, I have to build a dc motor control system using a uC. Can someone please help with the steps i need to take to do so and also where i can find a good lecture on simulink. I have done a little bit of research and i know am going to be using a PID controller. Thanks
this looks similar to facilities of Microchip's Mecatronics board Mechatronics Demonstration Kit which uses ECCP (Enhanced Capture Compare PWM) to control a Brushed DC motor Have a look at the Mechatronics Demo Board User?s Gui
Hi, Speed control using resistors is not correct approach techincally because you are controlling voltage where as for DC motors you need to control current. So I think you should look for current control instead of voltage control(this is only AC motors). Thankyou
How to control a dc motor with pic usin ccs compiler ? what are the basics i have to know ? I have the basics of programming in ccs, and i know how a dc motor works, but i don't know how to control it with pic microcontrollers. how necessary is to use the technique of pwm to (...)
The most common form of relay based DC motor control is to use the relay to switch the motor contacts to control the direction the motor runs. Relays can also be used to control speed by switching contact between voltages to apply to the DC motor. Hope this helps. Tahmid.

Hi, I want to control a 4A DC motor in a bidirectional way with PIC16F877A however,I do not figure out the input pins 5,7 and some net sites it is stated that input for pin5 and pin 7 must be pwm, however, the square wave for these pins should be inverted form.(see that attachment) In datasheet, I can not see this explanation. I wrote fo
Hi all, I'm trying to control a simple DC motor using a motor driver chip (L298) through programming the PIC16F877 microcontroller. I'm trying to come out with a simple code which will move the motor by a quarter with respect to its initial position and then stops. I need this (...)

If the boat design will require an onboard microcontroller, then using 802.15.4, ZigBee, MiWi or similar transceivers might be the most straight forward method. As not-a-moderator mentioned you can use a simple ASK type TX/RX with proper encoding/decoding, however the depth sensor, servo and DC motor control would require additional sensors (...)

you can control the speed of a DC motor using PWM and 5KHz should be OK however, speed is not linear vers PWM width as you have to overcome the resistance of the bearings + load etc but is OK for simple applications for discussion of alternatives have a look at Microchip's motor control pages
I was wondering if anyone could suggest a robust DC motor control system capable of being driven via Radio control, capable of controlling 12 or 24 volts at currents up to about 60 amps, and is reversible
I have a mosfet that controls a dc motor. Without snubber, mosfet gets hotter and hotter. With a diode snubber, this time diode gets hot. I used a slow diode. I'll also try a fast diode but i wonder that does snubber helps to reduce the dissipated power or does it take it from mosfet onto itself? I mean, must i use a huge diode or can i reduce comp
