Question
Choosing a servo

Hey, I'd like help in knowing what "strength" servo i'll require for a task. I need a servo that will be able to pull the disc brake cable of an electric scooter. I have a servo with a stall torque of 1.5kg/cm at 4.8v. I will be running the system at 5vv.

Will this be sufficient? Or how will I go around choosing a sufficient servo?

Thanks, Harris

5 watts is not much. You will probably need a lever, or gearing to keep the amp draw down. To really figure it you need to know how much force it takes to pull the cable, how far, and how fast the cable needs pulled.

If you only need to apply the brakes once, you could use the servo to pull a pin, to release a spring. The spring applies the brakes.

That's an air brake thingey and a reverse wheelie on a scooter. That would go viral on You tube with blood and all.
