Hi all, thanks again for any input.
I have been asked to look at this starter as motor starts ok, but when switches over to run motor stops and starter just hums.
First of all like I’ve said in previous posts I haven’t had a lot of experience with motors/ starters etc
Am I right in thinking this...
Have had a Makita BHP458 (non-brushless) hammer drill for years, I love it, it's pretty indestructable and the torque's great, but the chuck's finally going.
They seem to be moving to brushless motors now (for most of their combi drills). I've only recently bought a battery SDS drill (after 2...
Im designing a product that has an analog electrical system in which i have multiple fans.
im thinking of using a Reed switch to let me know if my Fans are working.
My thought was that when a motor is spinning, it is creating a magnetic field that would close my reed switch. if...
Hello, I've found an old motor originally designed for operating jealousies.
Could you help me read and better understand the following schematic?
As far as I understand, it is a single phase induction motor, there is 47 uF capacitor connected to it in order to start.
There are 3 contacts...
I am starting to get into brushless motors but am still having a hard time understanding all of the terms. I am reading books on electric motors and wiring but still need some additional clarification. I am purchasing this brushless motor: Amazon.com: DYS D3548 1100KV Brushless Motor Outrunner...
I am building a motorized easel for large format paintings that do not exceed 100 lbs; average probably more like 50 lbs max. My rough 3D diagram does not show the motor or pullies, etc, but I hope you can get an idea of where these things would go. Motor mounts on the bottom. Cables will...
Good day everyone
This is my first thread here, and I'm writing because I have a problem which I'm not sure how to solve. Since its company money, I just want to make sure that the conclusion to the problem is correct.
We have an autoclave that works at 121 celsius to sterilize with steam. Its...
I purchased a bench polisher which looks to have come from China. It says its 220v single phase and should work fine in the UK. The power cable has 4 wires in it so I'm confused how to wire a standard UK plug. I have attached a photo of the cable.
Any advice would be much appreciated.
I have a two value capacitor motor from china photos will includes i believe there country runs 220 standard single phase and I am in USA
Sn: it did spark accidently when i hit black wire on another wire and kinda started
I have been asked to run a supply for a single phase, 3.2a extract fan (systemair AW500E4).
Is it a requirement, recommended or just good practice to include thermal overload protection in such a situation?
hi guys i have an issue with one of two motor running star delta for a concrete mixer one motor is pulling out more current than the other one almost 10A difference (1st=39 , 2nd=48) knowing that the 2nd is rewinding both motor are same company
Hi, Minor time DIYer mostly doing little fun projects, so my skill level is a bit limited.
well, I also have a 3d printer. Now, I know all electrical motors generate AC power when freely spinning. Problem is, when there is a need to manually move the head or the build plate, this, of course...
Interesting old machine still in use. I've talked about similar motors before but not this type AFAIK. To the trained eye, the shape of this one is a giveaway, from which you can identify its maker and the technology it uses, and probably say something about the available electrical supply. In...
Hi all Newby here in dire need of advice
I have managed to lose the wiring order on my fiat fiorino van starter motor
I have 3 wires
1 Goes to alternator
1 goes to battery
and 1 goes to either ECU or ignition
Battery has 12.97 volts (its Fine)
The battery definitely connects to the empty...
A mate of mine recently acquired a rather nice wood turning lathe they'd like to get running out in their workshop. However he admits his workshop is rather old and while he's not bothered, I'm concerned about drawing too much current (I'm trying to convince him to get the wiring...
I have acquired an old British Thompson Houston 1/3 HP BKS 2410 single phase motor on a pillar drill, it needs new bearings before I can test run it, my question is can I use a multi meter to check the windings and find out if its a go-er at this stage and worth restoring ?
If so how ?
Hi I have a question on soft starts. Why do soft starts have motor FLC delta /1.73. I’m confused as I understand star delta it is set at 58% of the full load current as the overload is in line with the windings. Thanks for your help in advance.
Hello i have for sale the parts of this scooter.
Everything is working fine is just the holding mechanism is a bit wiggly(missing a screw) and the speed indicator is not working. The cable from the battery to controller has been worn out so i think this might be the issue.
The scooter is one...
I have a 550W 3ph electric motor / pump and a VFD which is a 220VAC input to 220VDC which is connected to my motor, so my motor can start at a lower speed until reach 1,390 rpm, also I have a 12VDC to 230VAC pure sine 1000W inverter, my question is: If I use a car alternator that...
Hi recently was on a job carrying out EX inspections on three phase motor at a pharmaceutical plant. The supply cable going to the motors does not have a core for the earth they have used the braid/SWA of the cable for earthing. So entering the three phase motor with EXe cable glands terminating...
Good evening you sparky lot
I'm after some wiring advice on an old single phase motor for use on a lathe. Please see the attached pics. The tails have been removed for clarity. Live was connected to terminal B, neutral to AZ. Is it possible to reverse the direction of this type of motor...
Hi all, hope i can get a bit of help here.
I have a dust extract in my shed which i use when i am turning. This morning i went to switch it on and it blew the 13A fuse, i replaced it hoping the fuse was at fault which it wasn't, well i had to try.
The motor plate 230v, 13amp, 2 pole, single...
Customer has this 110KW (converted to 55KW) motor powered via a generator.
They had a problem with the generator cutting out on startup showing overload fault.
Having investigated this issue, along with the motor overload having been bypassed!! (will be rectifying this!)
when I took the...
Question for someone... I have a 3P 1.5kw motor gearbox on a 5meter conveyor driven by a 3.7kw omron VFD, Frequency is set at 70/80hz (required for needed speed on this existing drive train) and voltage going out to motor is something crazy like 470v between line and earth, Its way to high I'm...
Hello, a mechanic friend asked me to check his hydraulic vehicle lift controls as it had failed. When I arrived the lift started working again (of course) but with some contactor chattering upon initial start for approx 5 seconds.
He was happy it was working again and wanted to get home, I had...
Hi All, Due to unforseen circumstances I have inherited a chicken farmer as a customer. He has just taken on another free range egg unit and wishes to install motorised 'pop holes' so that he can remotely open and close the doors for the chickens via a GSM module.(there are also push buttons in...
Hi all, I was asked in the office last night what size cable would be required for a 12V 1000W windlass with a cable length of 14m. I know how to calculate but where do you find the tables for 12V volt drop etc?
We've had a few threads about phase converters recently. Here's one I repaired on Monday. It's a little box that takes in single-phase 230V and feeds a 3-phase motor wired for 230V delta. It includes a manual 'soft' starter and overload relay. Unlike the units in the other threads, this one...
which factors might affect the slip and what losses may be incurred by the motor ?
Cannot find much about this, i know that the load indirectly affects slip due to the rotor speed changing, more load is more slip
Any assistance is appreciated, thank you
If any websites is found in referance...
what is the affect on starting current and torque of changing the electrical supply frequency?
I can find out that the speed changes etc from this website:
Changing an Induction Motor's Power Supply Frequency Between 50 and 60Hz -...
Hey guys! First post here
I just came across a broken fan that uses this can of motor to spin the blade, I already tested everything else for faults and it is the motor that is not running.
My question is this, given the simplest type of AC motor, what are the common causes of failure?
Hi, I'm Dave and I was wandering if I could have help with something.
If I were to wire a 5KW motor what means of protection should be incorporated into the inverter for compliance with BS 7671?
I have a 2003 ford transit petrol that has just had a replacement engine fitted
The van was started and ran for a few miles without any problems I stopped the van and went to get a coffee
when i returned to the van it did not want to start, thinking it was just fuel and a flat battery i went...
This isn't a job, just so that you know. Just exploring.
I have a couple of AC motors and I am playing with them. One of the things I want to do is measure the current draw.
So I attach them to a power source and switch it on and off they go doing their thing. No problem there...
