Danaher Motion AKM21E-BNMNC-00 servo motor

The performance characteristics of a brushless servo system (motor/controller 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.

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 controller’s rated continuous current output, whichever is less. The system voltage line is set by the voltage rating of the controller, 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. Refer to the Test Conditions on the pages that follow.

The intermittent duty zone is bordered by the peak torque line and the system voltage line. The peak torque line is set by either the controller’s peak current rating, which the controller 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 Danaher Motion Customer Support for more details. The system voltage line is set by the voltage rating of the controller, 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.

Current brushless drive technology uses a sinusoidal output. Danaher Motion rates its systems using RMS values to accurately reflect system performance operating with a sinusoidal waveform.
