The Many Uses of Digital Servo Motors
Digital servo motors are very popular and have been used for years. They are a great alternative to the old style screw driven motor. The main advantage to a digital servo motor is that it provides high torque, low speed and high power consumption. Compared to other servo motors, they are extremely low in maintenance.
The main technologies that go into digital servos are: analog to digital convertors, which change an input voltage into an output voltage, and microprocessor control, which enable the control of the motors state within the confines of the microprocessor. The microprocessor is a special type of computer that controls all the functions and settings of the digital servos. It also includes a digital input connector (DIP) and an analog output connector (as). The physical connection of the servos to the microprocessor is through a control interface or connector.
Most RC helicopters and airplane models today use digital servos, which makes controlling them much easier. If you are looking to get started with radio controlled airplanes, you might want to consider starting with helicopter choppers. There are a number of different helicopters to choose from, including the Quaker, Atec, Hughes 300 and Cessna twin engine RC helicopters.
If you are interested in building a remote control airplane, you might want to look into hobby stores to find RC helicopter kits. These kits usually contain the most essential parts for building a complete remote control model. The major components of these kits include the helicopter body, the tail rotor and propeller. You can also find after-market accessories such as speed boosters, battery cables and throttle sticks. Most RC helicopter kits are intended for beginners and intermediate users.
The advantage of using a servo motor is that you can regulate the amount of thrust or speed of your RC aircraft. The largest servos allow you to increase the RPM of your motor allowing it to produce more thrust or increased speed. However, you should be careful when changing the RPM of your RC vehicle since changing the amount of torque can lead to instability and poor maneuvering. Since there is considerable variation in RC servos, the ability to change the torque can be a challenge.
There are two types of servos: on-center and off-center. The on-center servos have one shaft that is completely encased in a housing whereas the off-center type has two shafts that are housed together but are not encased in a housing. The advantage of the on-center type is that it is easier to control; however, it can produce weaker torque. The offset styled servos are usually more reliable and produce stronger torque. The two different styles can be mounted in many different ways; however they are typically mounted on the edge of the RC car.
