Description
The Servo Motor MG996R 360 Degree Continuous Rotation is a standard-size servo with good torque and moderate speed.
Package Includes:
- Qty 1 – MG996R 360 Degree Continuous Rotation Servo motor
- Qty 4 – Arms/horns for various interface applications
- Qty 5 – Screws for mounting
- Qty 4 – Rubber and brass bushings for mounting
Key Features of Servo Motor MG996R Continuous Rotation:
- Standard (medium) size servo
- High torque of up to 13kg/cm
- Continuous rotation
- Metal (Brass & aluminum) gears
- Analog drive
These servos have good torque for the cost and work well for experimenting with robotic motor drives and similar applications that require a fair amount of grunt. The MG996 has a little more torque than the otherwise very similar MG995
The high torque capability comes at the expense of fast speed of movement due to the gearing. A 360 rotation takes about 1.2 seconds which is 50RPM.
Unlike normal servos that can be commanded to an exact position within a range of about 180 degrees, these servos rotate continuously in either direction with no ability to position to a particular position. Think of them more like DC motors with a motor controller built-in that powers the motor and allows you to start/stop and control the direction of rotation. Speed can be adjusted somewhat when operating near the midrange of the PWM.
These types of servos are handy for driving wheels on a robotic vehicle or if you just want to spin something around.
360-degree servo motors are comprised of a DC motor, gears, and a small electronic control board.
These servos are driven by a PWM signal. if using the Servo.h library as shown below, a command of about 90 will cause the servo to stop. A value of 0 will cause it to turn in one direction at full speed and a value of 180 will cause it to turn in the other direction at full speed. Values close to 90 will cause the motor to run at something less than full speed.
Motor Connections
The built-in cable has a 3-pin female connector that is usually mated with a male header.
