Latching relay (start - stop) Circuit Wizard simulation
Переглядів 2 тис.Рік тому
This circuit uses a normally open (N/O) push-to-make switch to latch the relay on and a normally closed (N/C) push-to-break switch to reset the latch. When the start switch is closed, the coil is powered and the relay contacts change position. When the start switch is released, the coil remains powered via the relay contacts until the stop switch is pressed. NO SOUND ON THIS VIDEO

WEG CFW300 VFD failure on surface grinder
Переглядів 375Рік тому
Is this a common fault? The VFD is just over 2 years old and appears to have failed. It spins the motor up no problem but appears to indicate an output frequency of 60 Hz (contrary to the programmed settings) and has an intermittent fault on the screen. I've tried reseating the internal interconnect between the display and main board but the fault remains.

Harrison 14 inch swing metal lathe for sale
Переглядів 1,1 тис.Рік тому
Posting this video to help a couple sell this lathe on behalf of their elderly father. The sale is genuine and the lathe appears to be in good vintage condition. The lathe comes with a 4 jaw independent and 3 jaw self centering chuck, fixed steady rest, travelling steady rest and at least two faceplates (I think). The lathe is housed in a home workshop with reasonable access via a tarmac driveway.
HSS shell milling cutter | Adcock Shipley 1ESG vintage milling machine
Переглядів 874Рік тому
A short video showing my Adcock Shipley 1ESG milling machine in action. I'm using a HSS shell milling cutter (on a 40 international taper shank) to machine some scrap mild steel that will be made into replacement jaws for the milling machine vice. In this video clip I'm taking it easy with a depth of cut about 3 or 4 mm and 20 mm wide. I'm applying soluble cutting oil with a hand held sprayer a...

Milling through cast iron vice | Adcock & Shipley 1ESG milling machine
Переглядів 688Рік тому
A short video (no narration) showing a HSS shell mill being used to mill through the body of a cast iron milling vice. The vice is being milled down and will be converted into fixture for a surface grinder. Spindle speed is about 200 RPM and feed rate is about 20mm / min (0.8 in / min). Feed rate can be increased without excessive vibration. There is some vibration on exiting the cut and I inte...

It is currently fitted with a virtually brand new and not cheap single to 3 phase vfd and 3 phase motor. I am considering all *sensible* offers with or without the vfd and motor in the deal. I have other motors if needed. The back gear works well and is not damaged. The lathe bed is marked in places ...
Black and Decker 6" Junior Bench Grinder Polisher (Vintage - possibly 1950s/60s?) NVR upgrade
Переглядів 3572 роки тому
A random look at my vintage bench grinder / polisher which may date back to the 1950s / 1960s. As you can see from the video, it is in excellent cosmetic condition and full working order. The original rubber coated / sheathed wiring was deteriorating and so it was trimmed back to the windings and new tails fitted. You'll also note that I added an NVR switch which I consider to be much safer tha...

      Too many to have them all in series. You could split them into 3 parallel branches of 4 resistors each. Other conditions also possible. Each branch would need its own current limiting resistor. To calculate the resistance and power rating you'd need to specify the LED forward current.

    When you are calculating the energy stored in the coil, as you assuming that it is oscillating at the coil’s resonant frequency? Because a coil’s voltage and capacitance varies depending on the frequency of the LC circuit and it only achieves it’s maximum energy storage value when it is oscillating in resonance.

    In practice, I found it difficult to get reliable values for the inductance L for solenoids. The iron losses are highly dependent on frequency, which is not well definable for this switching circuit. If there is a better way, please let me know

    • @PizzeyTechnology
      @PizzeyTechnology 2 місяці тому

      45W if I remember correctly. However, I don't think the wattage is important for this switch as there isn't a lot of thermal mass to the connector. I believe I could solder the same switch using my 15W iron.

      @@PizzeyTechnology I tried something similar the other day with no luck. I didn't hold the wire and terminal; they were simply floating in the air about an inch from where I held the wire in a vice. I think I need to hold the terminal better so the soldering iron can touch it better and let the heat sink in. It's not the soldering iron; it's my technique.

Should i use LCR meter to measure the inductance of motor? Is that a correct way? If not then can you calculate the Energy from the spike using oscilloscope? Thanks.
