SJME Junma

Specifications & Features

Features

  • Junma servomotors have an integral 16 bit encoder and are available with an integral holding brake for reducing the number of components in your system.
  • Quick disconnect power and encoder cables provide plug and play connectivity from the Junma amp to the Junma motor.
  • All Junma motors are tested and documented with a matched servo amplifier or SERVOPACK. These combinations optimize the amp and the motor for high performance, low cost, and small size.
  • Junma servo motors provide 7 times the acceleration power than a stepper motor of comparable volume.
