Method for adaptively engaging a clutch for a motor

摘要

A method for controlling a clutch for an air conditioner compressor having an armature and a rotor separated by an air gap width powered by an internal combustion engine having a crankshaft includes the steps of receiving a signal to engage the clutch, moving the armature to the rotor over a predetermined time to reduce the air gap width to zero, measuring rotational acceleration of the crankshaft of the internal combustion engine, and changing the predetermined time to reduce the air gap width to zero such that subsequent movement of the armature reduces the changes in the rotational acceleration of the crankshaft.
