M-Series Servo Motors

ORMEC’s M-series AC brushless servo motors provide high torque-to-inertia ratios and excellent continuous torque and peak torque performance in a compact design. These industrial quality servo motors incorporate high performance neodymium permanent magnets and a highly efficient stator winding design which results in excellent power density while maintaining low cogging characteristics.

Key Features

• Continuous Stall Torques from 1.4 to 248 in-lb (0.16 to 28 N-m)
• High Peak Torques from 4.4 to 557 in-lb (0.5 to 63 N-m)
• Output Power from 50 to 4,400 Watts (0.07 to 5.9 HP)
• High Maximum Speeds from 3,000 to 5,000 RPM
• Incremental Encoder resolutions up to 24,000 counts per revolution
• Optional Absolute Encoders feature multi-rev operation up to 1,048,576 cts/rev
• Class F Insulation over Class B temperature rise provides additional thermal headroom
• Minimum Torque Ripple & Cogging for smooth low-speed performance
• Totally Enclosed Non-Ventilated (TENV) standard IP-65 except shaft opening
• Optional Fail-Safe holding brakes

The M-series servo motors 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.

Motor/Drive Combinations

The performance of these servo motors is a direct function of the factory-matched servo motor / servo drive combination.

ORMEC's ServoWire drives provide software controlled all-digital performance for consistent operation that totally eliminates analog potentiometer adjustments. High bandwidth operation and a quality high resolution encoder provide the response and accuracy for demanding applications. Peak torques up to three times the rated torque are available for a few seconds, allowing the motor/drive to handle high inertial loads and heavy duty cycle requirements. Each drive's motor parameters are configured in software for high performance and RMS current limiting.

Absolute Encoder Option

Cost-effective absolute encoder support provides axis position over a range of 65,536 revolutions. In continuous uni-directional operation, the position count continually "wraps" through the full range while maintaining absolute position within the cycle. Position is maintained through power cycles by a lithium battery (optional) on the ServoWire digital drive.  Call ORMEC for ordering information.
