Duty Cycle Calculation - JBL TUNE600BTNC Quick Start Manual

Other application forces also need to be taken into account such as friction and external forces; however, for the
sake of simplicity, they will be ignored in this example.
Force RMS:
If this move were to continue cyclically then this result could be used with a forcer's continuous force rating for
forcer model selection. However, in many applications, a positioning move such as this would have a delay
before the next move which impacts the overall continuous force rating. If the above example were to have an
additional 1 second delay before the next positioning move, with no force required during this period:
Force RMS:
The result is a significant reduction in the required continuous force rating of the forcer.

Duty Cycle Calculation

The duty cycle of a linear motor is defined in terms of power usage and can be used to determine whether the
application RMS current (
keep the linear motor within its specifications. Exceeding 100% duty cycle could result in damage to the motor.
