Servo MG90S Rotação Contínua TowerPro
The Servo Motor Micro MG90S – 360 degree continuous rotation servo is a micro size 360 degree analog servo with metal gears and robust construction.
1 MG90S 360 Degree Continuous Rotation Servo motor with attached 9.5″ control cable
3 arms/horns for various interface applications
3 screws for mounting arms to the servo and mounting the servo
KEY FEATURES OF SERVO MOTOR MICRO MG90S – 360 DEGREE CONTINUOUS ROTATION:
- Very small micro size
- 360 degree continuous rotation of the shaft
- Sturdy metal gears
- Analog drive
Unlike normal servos that can be commanded to an exact position within a range of about 180 or 360 degrees, these servos will rotate continuously in either direction with no ability to position it to a particular position or to control speed. Think of them more like small DC motors with a motor controller built-in that powers the motor and that allows you to start/stop and control direction.
The gears are heavy-duty metal. The speed of rotation is fixed at about 120RPM.
These types of servos are handy for driving wheels on a micro-robot where space is limited or if you just want to spin something.
These are driven by a PWM signal. A pulse width of approximately 1500uS (PWM value of about 185) will cause the motor to stop. A higher PWM value over about 195 will rotate the motor in one direction while a lower PWM value under about 175 will cause the motor to rotate in the opposite direction. If the PWM value drops below about 500uSec (PWM value of 62), the motor will also stop due to insufficient drive.
If using the Servo.h library, as shown in the code below, a command of about 90 will cause the motor to stop. A value of 0 will cause it turn in one direction at full speed and a value of 180 will cause it to turn in the other direction at full speed.
The built-in cable has a 3-pin female connector that is usually mated with a male header.
