AppendixANCA Motion D-000168 Rev 02 379Other application forces also need to be taken into account such as friction and external forces; however, for thesake 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 forforcer model selection. However, in many applications, a positioning move such as this would have a delaybefore the next move which impacts the overall continuous force rating. If the above example were to have anadditional 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 Calculation9.1.2The duty cycle of a linear motor is defined in terms of power usage and can be used to determine whether theapplication RMS current ( ) is too high for the chosen forcer. A total duty cycle less than 100% is required tokeep the linear motor within its specifications. Exceeding 100% duty cycle could result in damage to the motor.( ) ( )
