servo motors By royldoc (Read 716 times)

I was awakened by thunder storms and couldn't get back to sleep. So I picked up a copy of model airplane news. Radio controlled planes and helicopters is one of my other expensive hobbies. Anyway I came across an add for servo motors. then I got to thinking. I wonder If I could replace the throttle cable with a servo and driver. Now the reason I'm thinking of this is because when I changed the carburetor to a 24mm the throttle cable was not long enough and I had to modify the cable bracket and move it closer to the operating linkage. If I wouldn't of been able to do this I would have to replace the cable. If it had a servo it would have been as easy as loosening the clamp and extending the cable. Any thoughts on this?

Throttle by wire, even driving by wire. It's all servo actuated and seeems to be the evolving system with the computer controlled vehicles. I'm at that age where I'm torn between giving it all over to a machine or retaining some direct control. It seems rather silly for the computer to generate feedback feel so you think you actually have a throttle hooked up to your bike or even a real accellerator. In answer to your question, it obviously works and is probably a superior system. Rich

It does not seem to be worth for such small vehiclea and it would add another point of failure since it would require power source off the votalge regulator (if there is something wrong with the D/C voltage you would lose throttle). If the battery was too weak you would need to kick start it and slightly open the throttle, but there would be no throttle response. Besides it would be more likely for the small serv motor to fail than for the cable to collapse.

longer throttle cable is cheaper than a cervo...but check the price on Hobby shop.com
..good luck with your cervo-activated scooter!!

well the cost and effort would be better sepnt on proximity starter kill or anti theft device !!! just run switches and the fob to complete the switched power .
