PWM an electromagnetic (A/C) clutch?

[Shannen Durphey]

Clutches used on GM systems probably would not like being PWM'd.  They would
spend more time in slip than in engagement, and with any type of load these
clutches fail fairly quickly when slipping.  They're steel to steel, ya know. 
Now if you could figure out a way to place a friction lining between the steel
drum and hub  without adding enough material to prevent clutch operation, you
might have a working design for a "slipping" electromagnetic clutch.
