What is Servo Motor?
| Servo Motors |
|
A motor used for motion control in robots, hard disc drives, etc. Generally designed more like an alternator than a standard motor, most Servos need special control circuitry to make them rotate electrically. Some can be used in reverse to generate alternating current. A small box full of motorized gears that turns the steering or throttle linkage in an RC car. Available in a range of strengths and speeds, with the faster / more powerful servos more expensive than slower/weaker servos. Stock servos usually cost about $12-15 US dollars and are the standard servos that are included with most radio sets. These servos are fine to get a kit running, but in the future you may want to upgrade to stronger servos, especially for racing or for the steering of a large-tire off-road kit like the Nitro RS4 MT. |
