Material Utilization and Parts Use Flowchart
We are looking for clarification on the use of an electric wrap spring
clutch. This is a device that utilizes an electic magnet to attract a control
ring that is used to wrap a spring onto a hub. This device is not a solenoid.
There is no moving shaft or actuator. By definition a solenoid converts energy
to linear motion by a coil enclosing a movable iron slug. In this device, there is no movement, no movement into a 'locking' position. If the device is overpowered by
force, it slips and/or breaks.
In our mind, it passes through the flow chart as an 'allowable' part. We are
looking for further clarification. In past years, electric magnets were allowed
as long as there was no EMF that would cause interference to other controls
and robots.
