Quick introduction:
I just bought a sinclair c5 1 week ago, it was not running but the guy I bought it from assured me it was the brushed, oh well I spent 150 euro to get it off his hands so not a bad deal right?
Ok I dismantled the motor cleaned it and put it back together just like this guy:
http://www.camp0s.com/Smart/c5/blog/23_02/motor.php
Hooked it up pod comes on with all the lights (I did not attached the gearbox ) motor started...I thought great..
but after a letting go of the button....and trying it again, I just hear a clicking sound.
After 10 minutes I tried again motor starts up...but gets very hot!!!
What is wrong???
and another question, should I be able to rotate the motor with my hands? I mean how smooth should the rotor move in its housing?
-
Did you clean the contacts at the end of the armature where the brushes connect the power?
Can you turn the motor by hand?
More pictures from my web site.

Try connecting the motor directly to a battery.
Does it turn now?
There will be a spark when you first connect.
The motor will draw high current to start with.
The stall current of a motor is over 100Amps.

yep cleaned the contact looks like yours now:

when I tried to turn the motor on this side of the sprocket:

It is hard to turn.
thank you for the help so far, cool to so somebody will lend a hand
-
is there no harm connecting directly to the battery from the motor?
-
No there is no harm in connecting the motor directly to the battery, but just hold it in place when you do as its likely to jump when you connect power, if the motor is stiff to turn, make sure you have assembled it correctly as it should be very free
-
If the motor is hard to turn by hand and the bearings are free the permanent magnet is the place to look next.
Inside the outer casing of the motor everything is held in place with resin /glue.
The resin cracks and allows the inner part to move and obstruct the movement of motor armature.
If this has happened you will need to replace the motor outer casing. :(

I will post a youtube movie to let you guys see what is going on
-
OK here are the movies:

This show what my pod does, you can here the clicking sound from the relay.
This show that I cannot turn the rotor when I try to turn it:

I tried to connect the motor straight to the battery but just gives sparks. even if I hold it for a long time
HELPPPP!

as you can see on the inside drawing the only parts that can obstruct the turning if you have removed the gearbox are the bearings front or back the rotor versus stator or the brushes
opening the motor (2 bolds) will give you an answer
my guess is one of the bearings
-
bearings seem to turn fine on both sides.
and brushes does not seem to be the problem also...
So must be status versus rotor....What to do next?
-
open the motor, 2 bolts must be enough
see http://www.camp0s.com/Smart/c5/blog/23_02/motor.php (http://www.camp0s.com/Smart/c5/blog/23_02/motor.php)

a perfect guide to do the job
if you need help just come to arnhem

that is the guide I used (and it is a good one)
But I think my problem is the rotor(magnet) housing
I made some pictures:

This is a repeat of my previous posting which seemed to be ignored. ???

A replacement motor housing is available from us at C5ALIVE ;)

clean it out and glue it in again is no option???
anyone experience with it??
-
Hi! i'm the guy of the guide you are referring :D
You said you opened the motor, you should have 3 pieces: "the back" with brushes, the middle with magnets and the core with the rotor.
1) Do the two ball bearings rotate alone? one at the and, the other in the front inside the plastic head?
2) When you fit the motor toghether, have you used something to keep brushes in a back position to not collide with the rotor while you insert it in place?
3) With the motor unwired, it does not turn, right?
