3.2 Performance Curve Data
All EB rated values and performance curves in this document assume operation with
CD/SERVOSTAR drives, which includes Torque Angle Advance (TAA). For further details please see
Kollmorgen Servo Amplifiers & Torque Angle Advance .
System torque/speed information is designed to help select the optimum brushless servo
motor/drive combination. The nominal values in this data illustrate performance for the
recommended motor/controller systems
l
The performance characteristics of a brushless servo system (motor/drives combination) are
described by a torque/speed operating envelope. As shown above, the shaded areas of the
curve indicate the continuous duty and intermittent duty zones of the system.
l
The continuous duty zone is bordered by the maximum continuous torque line up to the
intersection with the intermittent duty line. The continuous torque line is set by either the
motor’s maximum rated temperature, or the drives’ rated continuous current output,
whichever is less. The system voltage limit line is set by the voltage rating of the drives, the
line voltage supplied, and the motor winding. The system can operate on a continuous basis
anywhere within this area, assuming the ambient temperature is 40°C or less.
l
The intermittent duty zone is bordered by the peak torque line and the system voltage limit
line. The peak torque line is set by either the drives’ peak current rating, which the drive can
produce for a limited time, or the maximum rated peak current for the motor, whichever is
less. Refer to the Rating Data on the pages that follow. Note: Higher torque levels may be
achievable at higher power levels.
Consult Kollmorgen Customer Support for more details. The system voltage limit line is set by the
voltage rating of the drive, the line voltage applied and the motor winding. Operation in the
intermittent zone must be limited to a duty cycle that will produce an RMS system torque falling
within the continuous duty area. The RMS torque value is a function of the magnitude of the
intermittent torque and the percentage of the time spent at that torque.
