Servo is an electric motor with a gearbox that can be rotated by a predetermined angle.
All servos for radio-controlled models are used to connect three wires:
the positive wire to power, typically 4.8V or 6V;
negative wire;
signal wire.
The control signal conveys information about the desired position of the output shaft. The shaft is connected with a potentiometer, which defines its position. The controller on the resistance of the potentiometer and the control signal value determines in which direction you want to rotate the motor to get the right position of the output shaft. The higher the voltage Servo , the faster it works and develops more torque.
The control signal is a variable-width pulses. The pulses are repeated at a constant rate. Servo position is determined by the pulse width. Increase or decrease the length of the pulse will cause the servo to turn clockwise or counterclockwise, respectively.
The speed of rotation is measured by time servo actuator rocking an angle of 60 degrees with a supply voltage of 4.8V and 6V.
Key features to select Servo
Servo vary in size: there are micro, mini and standard. Within each class sizes may vary slightly, but the average size servos approximately as follows:
Micro: 24mm x 12mm x 24mm;
Mini: 30mm x 15mm x 35mm;
standard: 40mm x 20mm x 37mm.
Servo are plastic, and metal gears carbonite. All have their pros and cons, depending on your goals and objectives.
Plastic gears relatively fragile, often broken in the fall model, but they are inexpensive repair kits and gear themselves virtually no wear.
carbonite in many respects similar to plastic, a little stronger than the last, and a little more prone to wear.
Metal gear is much stronger, well withstand drops, but are the most expensive repair kits and are highly susceptible to wear. Over time, the metal gears appears backlash and they must completely change every season.
Servo are analog and digital.
They are made from a single detail and three-core wire connection to control the same. The only difference is how the control pulses are sent to the motor.
Analog servo
At rest on the motor is not energized, and if only slightly bend the stick transmitter, the motor will go on a short voltage pulse. The more movement the greater impetus to stick to power the motor, and the faster the actuator moves to the desired position.
all analog servo problem is that they are slow and poorly responsive to commands small or when an external force moves them from their seats.
Digital servo
Miniature microcontroller analyzes the signal from the receiver and converts it into a high-frequency pulses control the motor. Unlike analog servo motor which receives control pulses 50 times per second, digital servo motor receives these signals more than 300 per second. It is understood that the pulses are shorter, but in such an amount of the actuator and accelerate faster. The result is a servo that has a fast response, smooth and fast set speed and excellent retention.
The only drawback of digital Servo - this higher power consumption compared to analog.
The company has GreenChip offers you to buy different models Servo and choose the servo specifically for your needs!
