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:
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 9.1.2
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 (
is too high for the chosen forcer. A total duty cycle less than 100% is required to
keep the linear motor within its specifications. Exceeding 100% duty cycle could result in damage to the motor.
