Ok fab, will do. Not sure how long it will be though, starting on the chair in the next day or two.

[Burgerman]

Motor compensation 2 pole 100 to 110
Motor compensation 4 pole 45

Get this reversed and it will either barely turn or ne out of control.

[Princess Myia]

These are the motors I am using plus spare ones.
Not sure if they are 2 or 4 pole motors

[Princess Myia]

Another

[Princess Myia]

Two more

The number of brush holders ... they are the black plastic covers over the metal blade that the wire pushes onto ... gives the clue as to the number of poles.

So yours appear to be 2 pole.

[Burgerman]

Correct. Fit only for the bin.

They are terrible. They look similar to 4 pole but really are bad. Even when new. And low in torque /weak, unreliable and have lots of backlash so they jerk every time you turn.

[Princess Myia]

Ok, thank you. Will have a look round for some 4 pole motors

[Burgerman]

Sunrise medical.
Used motors - seldom a good idea apart from just keeping something old running. Those are about the only bit on a chair that does wear out. They lose efficiency, range, torque, get noisy, develop backlash in cush drives and gears. Brakes wear, seize.

I take a set off a chair that I am about to rebuild, that SO FAR have never let me down every 2 years regardless. BEFORE they do. As I have did last week, that go straight in the emergency parts pile. That chair will be reborn, with every part either as new, or new, and blasted, analysed, measured, re powder coated, new upholstery, new bearings, tyres, motors, connectors, bolts (stainless steel, cap screws, polished), new footplate, rose joints, batteries, etc. Regardless of the way they look when stripped. Result is a new chair. One that will run for 2 years used abusively and all day every day with zero breakdowns or maintenance. I cant afford that to happen.

[Princess Myia]

Thanks for that BM, was just about to buy a used pair of eBay. Will check out sunrise

[Burgerman]

Sunrise parts (sunparts) will give you a part number. A high street dealer will give you a VAT free price. Less a little discount if you fight.

[Princess Myia]

Is this correct, before I order?

[Burgerman]

Only if you want a valve on the inside as well!

[LROBBINS]

To amplify on John(Burgerman)'s last post by quoting another of his what you need is:

one 2 inch (inboard), one 2.5 inch (outboard with valve hole) and a tubeless adapter for the centre.

Ciao,
Lenny

[Burgerman]

I have to add, that if your chair is reprogrammed to work with 110 motor compensation for the old 2 pole motors and then you retro fit 4 pole motors later on, it will be uncontrollable and very dangerous. It WILL run away hard, and refuse to stop and break your legs. So you will need to reset motor compensation back to 45 for the 4 pole motors.

Hi All, I'm trying to help a friend in need, he has a scooter with an S drive controller. It has a fault in that after releasing the fwd/rev lever it carries on for a short while (powered) before the electric brake comes on and power is cut to the motor. How advanced are these controllers? Could it be a fault with the plug braking or are the parameters wrong in the controller?
I'm happy to make a lead up but the setup software seems elusive if this will help?

Apologies for all the questions on my first post it's not something I work on, my day job is a senior forklift engineer, my work includes work on complex electric trucks so I have good understanding of the workings. Hence I got asked to look at the scooter.
Warmest Regards
Noel

Could be a programming setting. Check Messages...

[Noel]

Thank you to Woody and yourself, great help.

[ex-Gooserider]

If it was working properly before, and has started showing the problem, I'd be sort of doubting that it's a programming issue, as the programming is something that usually doesn't break by itself...

I'd probably start by looking at the drive control lever, and make sure it is actually returning promptly to center when released. If the lever is OK, I'd look at the connection between the lever and the pot and or at the pot itself... Seems more likely to me that you have some sort of issue with the speed pot not sending the signals it should on to the rest of the controller...

Hi woody, just making the cable up, you say you use a 47k resistor should that be 4.7k? I'm guessing the exact value isn't important.

[Noel]

It knows is at neutral as the brake does apply but the ramp down after releasing the lever is slow, it does got to neutral and I've checked the cabling. It was purchased second hand without being tested and it isn't known.

47k is what I used for the FTDI Cable

Thank you for the super quick reply. Will pick up a pack today from rs.
Will let you know how I get on.

Does this program work for pilot + on windows 8 or only windows 7

[Burgerman]

XP, XP64, all versions of these too: Win server 32, 64, win server 2003 32, 64, Win Vista 32, 64, and win 7 32 and 64, win 8 (and 8.1) 32 and 64. And on windows 10...


And that's free if you sign up here http://windows.microsoft.com/en-gb/windows-10/about

Cheers John.

John programming 100amp PM to run on your bm2 clone. f55s motors. after going through the 100amp settings
i have noticed that Motor Compensation(milli-Ohms) is showing 65
Does it need to be 40 as on 80amp Std PM settings. Due to different size motors and Chair it came off.
0bviously i have used your recommended settings you give in build spec.

[Burgerman]

45 FOR 4 POLE, 110 FOR 2 POLE.

65 will make the thing dangerous with 4 pole F55 motors.

[hank]

Thanks
