Egg turner

[Lapwing]

A mate has this egg turner/incubator thing. Part of it has never worked. It has a toggle switch "Level" - "Off" - "Turn"

The part that has never worked is the "Level" bit, apparently this is meant to speed the motor up so that the egg trays can be removed, you still have to wait and stop the motor manually when the trays are level, as it is now he has to wait hours (Turn position) for the trays to get to where he can get them out.

A few pics he sent me.

Re: Egg turner

It looks like a gear-reduction synchronous motor (one speed, non-reversible) that regularily moves the egg trays back and forth, mechanically.
Not a lot you can do with that and only two motor wires.

In the pics, motor wiring at the switch is violet+orange, but at the motor is red+grey. Follow the wires on the "Level" switch contact, should go to something interesting or nothing at all.

It originally might have used a different type of motor.

Re: Egg turner

From the switch the wires just connect to each other via a standard block mounted to the roof of the box.

The synchronous motors i have seen on youtube that connect via a toggle switch like this are for "reverse - off - forward".

When the switch is in the "level" position the motor stops. He has swapped the connections on the switch to eliminate the switch from being at fault.

Re: Egg turner

Hmmmm looking at that picture, the violet wire is at a funny angle to be connected in that block, don't you think ?

Re: Egg turner

Good spot on the colour change redwire, i didn't notice that, i must go to specsavers one day and get my eyes tested LOL

So now we are getting somewhere, the Violet wire from the switch has been cut ! He can see the end of it hidden in the middle of the wires (cable tied together).

So i bet you are correct about the motor being changed too redwire.

Cheers

Have you Ohmed out the purple wire to the motor. By the photo it seems like it might be broken inside the insulation at the bottom bend.
