Servo motor FS90R

This continuous servo motor FS90R with an 6 cm large wheel is due to its compact size perfect for control and regulation of small loads and thus a good choice for engineering. Operated with 5 V, this servo motor has a peak torque of up to 1,5 kg/cm.


Please note: This is a continuous servo motor. Unlike a conventional servo motor, this one uses a PWM signal to set the speed and direction of rotation instead of the position.
