How Does a Satellite Servo Motor Work?
The Purpose of Satellite Motors Satellite TV and Internet uses geostationary satellites–satellites that are always in the same position in the sky. A signal is bounced off the satellite from a broadcasting station down to the satellite dish at the consumer’s house. This satellite dish doesn’t need to move since the satellite doesn’t. Because different services use different satellites, some enthusiasts use satellite dishes controlled by servo motors. These dishes can be pointed at any satellite in the sky. Stepper Motor Basics Most movable satellite servos use stepper motors. A stepper motor is a motor which rotates in small steps. Often, it takes more than 100 steps for a stepper motor to make one rotation. Because of the small size of the steps, a satellite dish can be precisely adjusted to face in any direction.
