Junma servo motors

A new concept in drive simplicity
Medium inertia compact motor

• Peak torque up to three times continuous torque for
3 seconds

• Easy to install with prebuilt cables

• Motors with brakes are available

• No motor settings required, just plug and run

Ratings

• 230 VAC Single-phase 100 W to 750 W
(0.318 Nm to 2.39 Nm)
