Please anyone, guide me how to make a high current DC motor controller using 8051. What do you mean by "high"? What do you mean by "control" - sounds like you're just talking about stop/go? the idea i have thought so far is to use a relay Yes, that could give you stop/go control; A second relay could add forward/reverse. connected to a pin of port of 8051 You could not connect such a relay direct to a standard 8051 pin (unless it's some special chip with specifically-designed relay-driving pins). Search for previous threads on using relays. if current is too large, will the relay work?? Of course, you would have to choose a relay that's suitably rated for the motor! Or look for a "Contactor" http://www.aaroncake.net/circuits/cntctcon.asp or any other method for it... There are chips specifically designed for motor drive, and discrete solutions, too!

| try these ics | 01/01/70 00:00 | |
| for drivers, there is, in my opinion, ONE source | 01/01/70 00:00 | |
| I would use a MOSFET instead of relay | 01/01/70 00:00 | |

| Well i think that Relay is Best Solution for you, | 01/01/70 00:00 | |
| Not suitable - no speed control! | 01/01/70 00:00 | |
| 800 A ??? | 01/01/70 00:00 | |
| Are you sure? | 01/01/70 00:00 | |
| High is relative | 01/01/70 00:00 | |
| you need a H-bridge as has been mentioned | 01/01/70 00:00 | |
| Topology is simple | 01/01/70 00:00 | |

| good info | 01/01/70 00:00 | |
| The +1 karma point came from me,... | 01/01/70 00:00 | |
| relay will work ,but | 01/01/70 00:00 | |
| better power amp | 01/01/70 00:00 | |
