Abstract
A variable capacity wobble plate type compressor having an electromagnetic induction type rotation detector detecting an actual rotation of internal rotatable elements in the compressor, which has a flanged disc-like element having apertures formed in the flange of the element and attached to a drive plate support element rotatable with a drive shaft of the compressor and an electromagnetic induction type sensing element cooperable with the apertures of the flanged disc-like element to generate an electric voltage signal having a wave form having symmetrical peak absolute values of different polarities with reference to a reference voltage level and in no way influenced by the existence of a partial balancing rom portion of the drive plate support element.
