R88M-G_ G-Series Servo Motors Datasheet

Compact in size big in features

A wide range of compact servo motors to meet all application needs. When used with a SmartStep 2 drive, the G-series servo motors offer the simplicity and cost-effectiveness of a stepper with the added advantages of a servo system.

Peak torque 300% of continuous torque during 3 seconds or more depending on model
Servo motors supported by SmartStep2, G-Series and Accurax G5 servo drives
Cylindrical and Flat servo motors types are available
Encoder accuracy of 10,000 step/rev as standard and 17-bit ABS encoder as optional
IP65 as standard and shaft oil seal available
Motors with brake as option
