360 degree servo motor

[thek4]

I'm trying to find a light, low-power servo motor that can rotate through ~360 deg (does not have to go around more then once) and who can be "aimed" with a PWM signal. It don't have to move much weight, just rotate a few lbs. Most heavy duty servos for airplane models would do but they only rotate through 90 deg. If anyone has any ideas where i could find a servo like this it would be extreamly helpful,
Thanks,
Ken

Suggestion: Visit

http://www.thomasregister.com

and type Servo under Product / Service
that will return many useful categories pertaining to Servo
The following one, you will probably use most:
Motors: Servo and associated 276 companies with it to choose from. To get there quickly you may type Motors: Servo

Why wouldn't standard stepper or servo motor do this? A stepper motor will rotate one direction infinite number of degrees based upon step values commanded from controller. Likewise a servo motor will rotate one direction infinite number of degrees based upon encoder counts commanded from controller.

Most of the standard servos i have looked at on that site as well as others seem to be large, and requre high-end control boards. I need something that's not that arge and can be controlled by a single PWM input, which i have been unable to find.

Suggestion: Post the servo specifications just like others do and there may be something around.

Try looking at Maxon, MicroMo, Portescap for mini-servo motors.
