Hello all you out there. Thank you for taking the time to read this. I have recently been collection old big screen TV's (6 so far) for the fs mirrors and lenses. I have pulled a couple of color wheels and have what I believe is a good one and want to power it.
Can anyone with electrical knowledge instruct me on how to power a color wheel. I touch each combination on the ribbon cable but haven't got it to move only jitter some. I took a few pictures for reference. also if anyone wants a large fs mirror or some lenses shoot me a PM just pay shipping or stop by and I'll give you some.

How many connections are there going to the motor ?

If its 3 then I would guess its a brushless motor and you will need a brushless motor driver , If it is this then I think you could get away with a RC brushless motor driver and servo tester to control It ( speed only ) .

If its 4 Wires then I would guess its a form of stepper motor and would need a stepper motor driver .

thank you ionlaser555. I never understood these type of electric motors, now I have some direction. I will be doing more reading on them type of drivers to get to know them. I love this forum for the knowledge that is always fast and precise.

I'm guessing but almost certain with my guess.

The flat flex cable goes to the motor. It's a typical brushless motor same as those that drive the spindle on HDDs. the 3 pins are your typical 3phase brushless motor and the 4th pin goes to the center tap of the Y connection of the windings which is used by the motor driver to sense motor rotation.

The 3pin connector is probably from a sensor so that the projector processor knows which position/color filter is in the beam.

Ah , So these motors are wired in a star configuration instead of the common delta style you get on RC brushless motors ?

That's what I've seen in brushless motors in CD rom, HDD spindles. And also even in older floppy drives.

If you leave the 4th pin unconnected, an RC ESC can still work just fine for this type of motor.
