SG-90 Servo is an electric motor with a gearbox that can rotate at a given angle.

servo device.

SG-90 Servo Drive can be divided into 3 parts: motor, gearbox, control board.

    The
  • Motor is small, capable of rotating at a constant speed in both directions.
  • Gearbox is a mechanical gear unit that reduces the engine speed and transfers rotation to the output shaft. A variable resistor is connected to the gearbox to determine the current angle of rotation of the shaft (feedback). Also, the gearbox limits the maximum angle of rotation of the motor due to the pin.
  • Control board - converts input commands into a control signal for N- bridge, which connects the motor to the power supply (for right or left rotation). The board reads the readings from the variable resistor on the gearbox and compares the value with the command. It then calculates the difference and determines in which direction the motor should be turned to reduce the difference.

    SG-90 Servo has three wire connection:

    • land;
    • food;
    • control signal.

    To control the SG-90 servo drive, it is necessary to send pulses to the control wire with a period of 20 ms (50 Hz). The angle of rotation is set by the duration of the control pulse. You can adjust the pulse time using software or use a timer.

Прислали швидко, серво працює чудово. Взяв саме цей з аналогів через те, що на ньому металева шестерня, а не пластмасова.
