H-Series
Servomotors
 ORMEC’s
H-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 and a highly efficient stator winding design
which results in excellent power density.
The H-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

Optional absolute encoders feature multi-rev operation up to 1,048,576
counts/rev.
-
Class B or F insulation providing long winding life under rated operating
conditions

Minimum torque ripple & cogging for smooth low-speed performance
-
Totally Enclosed Non-Ventilated (TENV) standard IP-67 except shaft opening,
optional shaft oil seal is available.
-
Optional fail-safe holding brakes
Motor/Drive Combinations
The performance of these servomotors is a direct
function of the factory-matched servomotor/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 &
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 & 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 100,000 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 and
a supercapacitor in the servomotor.
