    Single phase motor

    If digital multimeter, select 200 ohm range and touch red and black probes together, you should get maybe 0.4 or 0.5 ohm reading. This is continuity ( continuous circuit) reading. So if one were to pick up a piece of wire off the workbench and place the probes, one each end, one would get the...

    Single phase motor

    Thanks for providing measurements. The answer to " the remaining wiring and their origin" is done using the multimeter, much the same as you have determined that the black on cap-1 loops to the cap-2 i.e. 0.5R reading. I can see from here that wiring disappears into concealed spaces. What you...

    Identification: MOSFET IRF520 type

    If any help.... I use either IRL3803...30v...0.006 RDS....140A (to220) Or IRL540N.....100V ...0,044 RDS...36A Either readily available Ebay or whatever......no too bad a price @ 10 units

    Is 24V AC dangerous?

    yes, did think about that. I guess one has to just assume sometimes.

    Sutibility of motor in fighting robot feather weight

    Even with the reduction gearbox the output is over 550rpm which I'm guessing would not be anywhere near requirement. You can work it out with a wheel of say 100mm diameter. Applying pwm speed control via a uC would be ok BUT your top speed would need to be assessed and applied to give maximum...

    Is 24V AC dangerous?

    Power supply input is 24v ac.... That seems strange .... no mains supply anywhere?

    Identification: MOSFET IRF520 type

    If you are using with Arduino then logic level would be necessary.

    Single phase motor

    "L" bracket and "Y" section of the switch (attachment 41930) appear to be burnt away....would that be a fair observation? Also could you provide these ...? Capacitor-1 Yellow to ...... Black to ........ Capacitor -2 Black to ...... Red to ........ Blue to ....... Readings Between Red...

    Single phase motor

    welllll....who knows:) Readings should be obtained with the multimeter on ohms x 1 range. If using a digital meter this would normally be the 200 ohm (lowest) range Anyhow, hold in there and we shall see. From closer inspection of the photos you supplied, the motor is more likely to be a cap...

    VU meter with zener diodes?

    Different color leds have differing voltage drops that you may be able to use to your advantage.

    Single phase motor

    Hi Lance, been busy...... Yes, if you know what to look for and you can follow a circuit diagram. See if I can find a basic one and you can have a try from there. To begin with, all ends will have to be disconnected from everything so I'd be inclined to do some marking of wires and even perhaps...

    Car horn as speaker for musical keyboard

    Must be surround sound as those mothers are noisy in any direction.

    Car horn as speaker for musical keyboard

    Most electric car horns operate by moving a metal disc which in turn opens and closes a set of pre-adjusted points, much in the same way as an electric bell. Speakers operate by applying a variable to a speaker coil that is surrounded by a magnetic field. Totally different principles.

    Capacitor for 240v 1/4 hp vintage lathe.

    In a standard run-of-the-mill connection plate, one would normally expect .... A1 and A2 to be the run winding Z1 and Z2 to be the start winding and centrifugal switch. Link between Z2 and A2 as a common point ( neutral supply) with capacitor connected across Z1 and A1. However........ the...

    Single phase motor

    Note:- the diagram on tha back of the wiring cover is the view from the exterior back of the motor, NOT internally. Also you may or may not have noticed, the way you show the photo of the terminals is upside down. There is also 2 versions shown , one with use of an overload(your motor) and one...

    Single phase motor

    Your last photos are different from the ones in post 4 above. You have taken away the black wire from T2, and fitted an overload wire, other red wire is missing alltogether. Do you have the wiring of the motor connected as in the last photo in #4 or is the last photo from some other time. Very...

    Sump pump backup

    Does not make sense. Can you try to explain what it is you are expecting to do?

    Capacitor for 240v 1/4 hp vintage lathe.

    Something does not appear correct there as there is no need for a start capacitor to go back to the reversing switch. Four cables yes, but 2 should be the run winding and 2 the start winding with the capacitor wired into the terminal block on the motor. Someone played with the wiring I...
