Called out to my local farm, who deal in fruit and veg, to a DOL starter switch which cuts out after a minute or so. This switch controls a 415V 5 amp 3 phase motor running a conveyor belt, and has done so for a number of years.
I replaced the switch with a second hand one I had...
Hi All
A while ago a customer asked us to move a 1970s single phase corn mill and return it to use.
It had an old series parallel starter with a lever on it ..which we replaced with a crompton controls series 3000 starter...all good and running.
Now they had another ip rated box attached to...
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...
I am looking to slowly start investing in some quality power tools and wondering which tools I should start with? Keen to hear which brand/model is deemed superior to others and why, although i'm sure there will be a range of opinions on this topic. I assume sticking with one brand makes sense...
Hi,
How do you set a motor overload? I have read that you set it at the FLA of the motor but also that you should consider service factor. Which is correct? Thanks.
What fuse rating do I need to put in between the starter and leisure battery? I have a 12V 75AH Starter battery and 110Ah leisure battery. Cable size 16mm or 8mm. (this is for my off the grid van :) )
Could I use a DOL Starter circuit to create an automatic extraction system? I was thinking that I could replace the start button and simply wire in a socket instead. So hypothetically if I plugged in and switched on an electric palm sander, it would start up my dust extraction systems (via the...
Hi
I have been called out to a fault on a grain dryer where the motor interlocks are not disconnecting. Previous conveyors. Upon investigation I have found one starter that does not disconnect the preceding motor but when tripped I am getting 550v to earth from a1 and wait for it 760volts to...
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...
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...
Not sure what this fits, its an old thing possibly 1930s??. its a lucas and the number on the body is 270300, it has 10 teeth on the pinion. its a 12v.
would appreciate any help given.

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...
Hi all I have a 3 hp single phase motor that only runs when you hold the button and stops when you release it. I am struggling to get my head around which contactor to get for it. Any help would be great.
Hi I’m sitting my AM2 next month and have found out that you need to set an overload on a direct online starter motor circuit.
I have tried asking my supervisor and assessor,tutor at college not one of them have given my a straight answer..
Is this the formula?
Its 3 phase so formula is...
Can't seem to find any standard circuit diagrams for sequential reversing starter. The metal detector conveyor has manual mode and automatic reversal mode. Need to prevent the conveyor from going backwards during false signals or anything else while the conveyor is standstill. It should reverse...
Hello Chaps
I have inherited a motor with no starter. I have therefore bought a new switch but i am struggling to connect up. I would be very grateful if any forum members could give me some advise should they be familiar with this setup? It is a single phase motor, and i am trying to add a DOL...
