Omron ACCURAX G5 SERVO MOTORS DATASHEET

R88M-K@

Accurax G5 servo motors

Servo family for accurate motion control. High response, high speed and high torque.

• Peak torque 300% of rated torque during 3 seconds or more depending on model

• High resolution serial encoder provided by 20 bits encoder

• IP67 protection in all models

• Ultra-light and compact size motor

• Low speed ripple and low torque ripple due to low torque cogging

• Various shaft, brake and seal options

Ratings

• 230 VAC from 50 W to 1.5 kW (rated torque from 0.16 to 8.59 Nm)

• 400 VAC from 400 W to 5 kW (rated torque from 1.91 Nm to 28.7 Nm)
