Description
The Servo Motor SG-5010 is a workhorse standard servo with a range of 180 degrees that can be used in many applications and is one of the best values for a general-purpose servo.
Package Includes:
- 1 SG-5010 Servo motor with attached control cable
- 4 arms/horns for various interface applications
- Screws for mounting arms to the servo and mounting the servos
- 4 rubber and 4 brass bushings for mounting.
Key Features of Servo Motor SG-5010:
- Medium size servo
- Strong, can lift 8lbs positioned 1cm from the center of the shaft
- 180-degree rotation
- Nylon gears
- Analog drive
These servos work well for both servo experimentation as well as incorporation into many medium-duty applications where their moderate size and good torque characteristics can be put to use. Gears are nylon which is the case with most lower cost Servos.
Servo motors can be commanded to go to a specific position and are the usual go-to motor when accurate positioning is needed, such as for turning the front wheels on an RC model for steering or pivoting a sensor to look around on a robotic vehicle.
Servo motors are comprised of a DC motor, gears, a potentiometer to determine its position, and a small electronic control board.
Standard servos have a specified limited range. This is usually specified as 180 degrees. Frequently the actual range is not quite the full 180 degrees and is limited by the mechanical gears and potentiometer used for position sensing that is contained in the device. If the motor is run all the way to 0 or 180, it may start making unhappy sounds and start vibrating as it tries to drive to a position that it cannot get to. This causes a high stall current condition and has the potential of stripping gears and damaging the motor, so it is best to either drive it to a safely reduced range such as 20-160, or experiment a bit to determine the actual usable range if you want to maximize the range.
Servos expect to see a pulse on their PWM pin every 20mSec. The pulse is active HIGH and the width of the pulse determines the position (angle) of the servos shaft. The pulse can vary between 1mSec and 2mSec. A 1mSec pulse positions the shaft at 0 degrees. A 1.5mSec pulse positions the shaft at 90 degrees (centered in its range). A 2mSec pulse positions the shaft at 180 degrees. Pulses with values between these can be used to position the shaft arbitrarily.
Motor Connections
The built-in cable has a 3-pin female connector that is usually mated with a male header.
