G-Series Servomotors

ORMEC’s G-series AC brushless servomotors provide high torque-to-inertia ratios and excellent continuous torque and peak torque performance in a compact design. These industrial-quality servomotors incorporate high-energy, rare earth, neodymium-iron-boron magnets for excellent power density.

The G-Series servomotors also completely eliminate brush wear maintenance problems, and feature extremely durable construction which includes heavy duty bearings. Rugged MS connectors provide reliable interconnections to both motor and optical encoder.

Features

Motor/Drive Combinations
Torque/speed performance of the G-Series motors is determined by the selected servodrive. All configuration parameters for matching drive to motor are stored on the ORION® controller and are downloaded automatically after each power-up.  Peak torques are also dependent on the selected servodrive, as is peak torque duration which is typically two seconds for the recommended drive.

The PDF file below contains the complete set of torque-speed curves, motor specifications and outline drawings for the all the G-series motors.
