Motor Servo Digital Definition
Servo motor is a motor that can work both ways (CW and CCW) where the direction and angle rotornya movement can be controlled only by giving the setting duty cycle PWM signal on the pin control. Type of Motor servo motor capacity determine the weight-bearing load. Servo Motor outline there are 2 types, namely 180 ° Standard Servo Motor and Servo Motor Continuous. 180 ° Standard Servo Motor is only able to move both directions (CW and CCW) with the respective deflection angle reaches 90 ° so that the total deflection angle from the right – middle – left is 180 °. Meanwhile, Continuous Servo Motor is capable of moving both directions (CW and CCW) without restriction deflection angle (can rotate continuously).

Servo motor will work best if given control pin on the PWM signal with a frequency of 50Hz. At which time a signal with frequency of 50Hz was reached on condition Ton 1.5ms duty cycle, the rotor of the motor will stop right in the middle (angle 0 ° / neutral). At Ton duty cycle of the signal is given less than 1.5ms, then the rotor will rotate to the left with an angle that the linear to the amount of Ton duty cycle, and positioned it will survive. And conversely, if Ton duty cycle of the signal is given more than 1.5ms, then the rotor will rotate to the right with an angle which is also linear tosize of Ton duty cycle , and ispositioned to survive .
