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...
Hello there.-
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...
Need a bit of advice about a motor rewire i need to do.
There is a 2.2kw motor which is supplied from an MCC with about a 30m ish run using a 4mm 4 core SWA. This then goes to an atex junction box located half a meter from the motor. Then the cable goes from this box to the motor itself.
For...
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...
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.
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?
Thanks! :)
