Remote Control 2 Motors - wiring help please :-)
August 18, 2020 - 6:31am

 Sorry about the diagram, trying to remote control 2 motors using a YK04 receiver, powered by 5v, 100k resistor, and STP36NF061 Mosfet. 9v battery to power the motors. Think have the 1st one ok, but unsure on adding the 2nd motor. 

Please any help be greatly appreciated..

Sorry. If mat trouble you once more. Never done any electrical work like this. The projects taken over 3 weeks to come up with to design the prop, then this on top. Heads in bits. So really appreciate your time taken out.

Could you be so king as to clarify a few things please?? As on the added drawing in baby terms :-)

Again appreciatedsbell drawing V3.PNG

No figured out the green lines, Just a reed switch i forgot :-)
August 18, 2020 - 9:32am

Yes now undersatnd the green intersections, but if wanted to add a reed switch or just a standard push button switch, and a led to show when system is on or off please????

Sory for my confusing diagram, 

First, you are absolutely right about the pinout of the mosfets.

Second, take a closer look at the point where the resistor R1 and the gate of the mosfet gets connected, saw a dot that means those two lines are connected. Otherwise its not connected.

Third, RED is positive, Blacks are Negative, some of the greens are negative and some are connection between components. let me explain,

The green wire coming from the source of the mosfet, has to be grounded.

The two wires from D0, and D1 gets connected to the gate of the mosfet.

I hope the image below will clear your doubts,

What type of motors you are using? if its a heavy duty one you need to add two diodes from drain to source

Again can not thank you enough, brilliant.

The motors are just small 3-9v actuators 

 

Best wishes

Those will work just fine without a diode.

mosfet failing
September 13, 2020 - 2:20pm

Hi, Strange used now 3 STP55NF06FP Transistor N Channel MOSFET.  As per diagram.Was given a few receiver transmitters, when testing see which of them are working and matching them up, the mosfets failing. Using 12v N type remote battery for the receiver, a 9v PP3 to power the motor. Cant figure it, 

Would then a diode be needed? if so could you please inform me if should be put on G D or source?

Thanks again

The circuit is ok but I could not see any snubber circuit for the MOTORs.

The major problem of a MOSFET that they are very sensitive when compared with Transistors. The connction with the Mosfet is need to be protected by a freewheeling diode. You can try adding single Diode 1N4007 in each Mosfet. Add the annode to the MOSFET drain and cathode to the Source. It will protect the MOSFET from failing.

A generic 1N4007 Diode for each Mosfet would be sufficient

Yes, debasis is right. Since your circuit does not use any freewheeling diode, I checked for snubber circuit. Snubber circuit was not there, so I asked you to put a simple diode of 1N4007. Use diode rather than snubber because diode will solve the purpose and relatively cheap and simple to use.

Call upon your services once again. Think i have lost the plot??
September 23, 2020 - 12:23am

Hello.

Again added diodes as explained. Have now tried 10 STP36NF061 Mosfets.

Mootor just runs, removed all connectors to the receiver, no difference. If have just the Drain to motor + positive. The touch the Source with the negative, motor just starts up again. Assume the mosfets are faulty? 

Thanks again

Having removed all connectors, 

them - from motor to drain, + battery to + on motor, - battery to the source, motor just spins.

Thank you

Try checking the MOSFET with a multimeter, in continuty mode.

1. Connect the meter's negative (-) lead to the 'Source' of the MOSFET.

2. Hold the MosFet by the case, nad don't touch the metal parts of the MOSFET.

3. With the meter positive lead touch the MosFet's Gate.

4. Now move the positive probe to the Drain. You should get a low readin, because the internal gate capacitance of the MOSFET is now charged by the meter and the device is now ON.

Such a simple test is not 100% -- but is useful and usually adequate.

Tested against a working mosfet, proved pretty good. :-) 8 out of 10 were bad :-(  The company needs me to send back, as think im trying to pull a scam :-(TEST.JPG

Thank you. Just seen some magical effects that has taken me away from my usual magic. As you know electronicts is not something i have encountered.  There is a few projects trying to figue out, thats a deep secrect, long past. Two of them by watching and banging head against wall have figured out. This is NOT! for profit but to learnand try to understand the mechanice. Did purchase 1 plan from a supplier, but the cost involved to post to UK, could nt relly justify. So again i much appreciate every ones feed back..

I am withing a few associates that are my magic mentors shaed my projects with them only, and have credited both the forum and those involed from this forum. Again thank you. With what i have produced has brought magic back from the early 1900`s. Long forgotten Unlike our tv Dynamo, Blain etc. I go back to the late long forgot classics as people you dont know in my feild as Slydini, a true 1900`s magician.  Again thank you for time and patience
