Selecting A Servo Motor
- Jun 12, 2018 -

When starting a project that uses servo motors, look at your application requirements. How fast must the servo rotate from one position to another? How hard will it have to push or pull? Do I need a positional rotation, continuous rotation, or linear servo? How much overshoot is allowable? The less you pay for the servo, the less mechanical power it will have to muster and the less precision it will have in its movements. You can pay a bit more and get one that moves quickly, but it may not have a lot of power. You can also buy one that will pull or push large loads, but it may not move quickly or precisely. Manufacturers' websites and online hobby guides will have a lot of this information you can use to compare models. You will also find that hobby stores have a selection of servos and can usually help you decide which one is right for your project and budget.
