Product Description

D7/D12 Servo Series Features

  • The most basic product group of mightyZAP with Position control feature
  • Built-in drive circuit, position sensor, DC motor and gear box
  • Reasonable price compared to the Force control 12Lf series
  • Suitable for customers who do not need current and speed control
  • Stall force and speed adjustment within a limited range by adjusting the motor operating rate
  • 12mm diameter coreless motor lineup and cored motor lineup
     * The coreless motor is superior to the cored motor in terms of force and durability.
  • 27/41/56/96mm stroke option (Based on coreless motor lineup)
  • Rated Load of 12N ~ 100N according to gear ratio for each stroke
    * Speed is inversely proportional to Rated Load, so the stronger the Rated Load, the slower the speed.
  • Support RS-485 or TTL / PWM communication
    * TTL / PWM communication version operates by automatically recognizing the input TTL / PWM signal
    * When using PWM communication, only the position command is available without position feedback (For feedback feature, use TTL or RS-485 communication)
  • IR open protocol available
