0.1 - 0.75kW, medium inertia

The Junma servo motor uses Yaskawa’s compact servomotor manufacturing techniques to deliver superior performance over stepper motors.


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.
