    How To Make A Up And Down Mechanism Like A Grabbing Machine By A Single Push Button

    If you want a motorized hoist for the crane, then this will entail a small reversible DC motor driving the drum, It might be a jump ahead if you can source out a suitable small crane that is already have the mechanical basics. M.

    Bypass motor on motor help

    It appears that you have the right idea, But that won't work, you have the field removed, this will not allow the motor to turn. You need to make the same electrical connection but with the field in place. Check continuity again with the field in place and try power again. The field consists of...

    How To Make A Up And Down Mechanism Like A Grabbing Machine By A Single Push Button

    Your right, it is a little vague! What actual part do you want help with? What mechanism is in place already or do you want help with the whole lift mechanism? M.

    Bypass motor on motor help

    Either attach directly to the motor or the red/blk red/brn wires. What continuity do you get across both the series limit switches? M.

    Bypass motor on motor help

    If those are the over travels in series with the motor, they each would require a reverse diode rectifier wired across them that when tripped would allow the reverse action to take place. Either that, or the opposite switch is stuck open. If you can take the motor off the limits and check...

    Hooking up deadbolt motor to TB6612FNG Stepper Motor Controller

    I would expect a DC brushed motor to turn when power is applied. with apply power across the two, what is the continuity across them? M.

    Bypass motor on motor help

    It doesn't have to be done with a fancy drawing package, just a hand drawn sketch of the wires and where/what/how they are connected . With wire colours. If you are not sure how to draw a certain component, you can google Electrical symbols etc. Telemecanique wiring diagrams M.

    Bypass motor on motor help

    I would have expected the motor and the reed switches to go back to the controller separately, as they appear to. The controller would need to be connected directly to the motor, or at least short the SW's out in order to run. What would be a good idea would be to draw it out diagrammatically...

    Bypass motor on motor help

    OK check the continuity across the two connections to the brushes, also check the leads from brushes to the circuit board. There is very little to go wrong, the motor itself looks in good condition. Barring a flaw in manuf. I suspect the fault is minor in nature. Bypassing depends on what the...

    Bypass motor on motor help

    If the red to blk shows open, then it does appear to be something in the motor, I would tackle taking the motor itself off if possible, and see if anything obvious, which sounds like a brush open circuit? M.

    Bypass motor on motor help

    A little late getting back but the red/blk (Brn/Red) appear to be the motor wires and the yellow/white are the reed switch inside for stop position. The motor wires will alternate polarity dependant on direction. See if you have continuity across the motor connections, I imagine the reed sw...

    Special Project with led and motors

    Wow, that PWM control shows as CAN$65.00! Roughly same thing on ebay is around $5.00. Maybe does not have the fancy knob and the switch, which can easily be added. They are all mostly 555 based and can even be put together one's self for ~ $5 also. M.

    Help Identify Component

    As already pointed out, it will show no continuity, it is a capacitor. A snubber is a term for a suppression device connected across an AC inductive device such as this case where it seems it could be across the contactor coil, the contactor or? It will operate without it, just that you may get...

    Help Identify Component

    0.1μf. Is this part of a relay/contactor coil snubber? If so the operating voltage of the circuit it is in will give you an idea of voltage rating. Do you suspect it bad, as it appears to be OK condition? M.

    Bypass motor on motor help

    I would check to see if you can remove the linear actuator for further testing, I am guessing that the cost is for replacing the unit as a whole instead of just the motor. See if you can identify any wires going into the motor directly, I see the motor is a 24vdc version so a large battery such...

    Bypass motor on motor help

    Usually with this kind of problem and very little to no manuf. data, you have to do a little reverse engineering and find out specifically what you have in order to pin the cause down. If you have not used this function, or very little, it is hard to believe the motor is shot. Linear actuators...

    Bypass motor on motor help

    That appears to be a linear actuator, normally they are DC motors, I am guessing the red and blk are motor, the other pair could be a limit sw, or? .Can you measure the resistance of the BLK/RED pair. If it can be determined which is the motor pair, you could apply an external DC voltage to it...
