Description
MG90S Metal Gear Digital Servo 450 Electric Straight Swashplate ServoProduct model: MG90SProduct size: 22.812.228.5mmProduct weight: 13.6gWorking voltage: DC4.8V-6.0VWorking temperature: 0℃-55℃Reaction speed: working speed: 0.11±0.01 second/60°(4.8V); 0.10±0.01 second/60°(6.0V)Stall torque: 1.6±0.01kg/cm (4.8V); 1.8±0.01kg/cm (6.0V)Working angle: 90±5°Angle deviation of left and right movement: ≤3°Response pulse width time: 5usecInterface type: JR, FUTABA generalThe package contains: MG90S servo motor × 8, multi-function swing arm × 24（8pcs 1.32inch；8pcs 1.22inch；8pcs 0.84inch）, fixed screw × 24（Metric screw，16pcs PWA2.0×8mm；8pcs PM2.5×4mm）Control principle: The control signal enters the signal modulation chip from the channel of the receiver to obtain the DC bias voltage. There is a reference circuit inside it, which produces a reference signal with a period of 20ms and a width of 1.5ms.The direct bias voltage is compared with the voltage of the potentiometer to obtain a voltage difference output. Finally, the positive and negative voltage difference is output to the motor drive chip to determine the positive and negative rotation of the motor. When the motor speed is constant, the potentiometer is driven to rotate through the cascade reduction gear, so that the voltage difference is 0 and the motor stops rotating. The control of the steering gear generally requires a time base pulse of about 20ms. The high- level part of the pulse is generally the angle control pulse part in the range of 0.5ms-2ms, with a total interval of 2ms. Taking the 180 degree angle servo as an example, the corresponding control relationship is as follows:0.5ms --------------0 degrees; 1.0ms------------45 degrees; 1.5ms------------90 degrees; 2.0ms-----------135 degrees; 2.5ms-----------180 degrees。
