Default Brushless motors in DVD player??

Ive heard of guys using motors out of a CD ROM player in a foamie plane. Im looking to build my own foamie and I am starting to acquire the parts. Have an old broken DVD player that I am not using, will the motors from DVD player also work?? What size ESC would I need??

Thanks,
Mike

If the DVD motor is a brushless motor with a multiple of 3 stator teeth, then it may be usable. The brushless controllers we use require a multiple of 3 teeth.

The current rating of the ESC depends on how many turns of wire you put on the motor. In most cases, the no-load current will probably be less than 2A. When you add a prop, you'll definitely want to have a wattmeter connected to monitor current consumption.

Most of these guys rewind and re-magnet the cdrom/dvd motors. Otherwise, you won't get much out of them. There are entire websites on the subject.

If you want to try it, go here for a start..... [link=http://www.gobrushless.com/ccp51/cgi-bin/cp-app.cgi]GoBrushless.com[/link]

Good luck

Do-it-yourself motor homepages, manuals, checks and tests in the first message of this motor builders tips and tricks thread. The checks and tests may save you from frying your controller. Thread is active, bookmark it for future refence and subscribe to it:
