Induction Motors
Posted: 29 Sep 2009
Anyone know shit about these? Apart from no brushes and the like.....
As in the one in my dishwasher don't work. AFAIK there are no open/closed circuits (vague I know) where you wouldn't expect them
It has a thermal device that i think is working ok. This thing changes it's resistance as it heats up. It's purpose is to help get the motor spinning (by providing out of phase mag field to main coils) and then keep it going (thermal thing changes resistance to (I'm guessing) reduce the phase lead)). Also there is a capacitor connected to the motor windings.
Other facts:
The motor is getting a feed.
The thermal device seems to operate as expected
The windings and associated contacts have resistances of 11.6 ohms, 68.3 ohms and 80 ohms
I have no idea if the capacitor is working correctly. It's not short or open circuit. What actual function does this thing do? I have managed to dent the aluminium casing a bit - would this fuck it up?
Even with the voltage applied to the motor, a manual kick start does nowt!
