ELECTROMAGNETIC CLUTCH

An electromagnetic clutch comprises a clutch rotor having a flange portion, an armature opposed to the flange portion, and a ring exciting coil. The ring exciting coil generates a magnetic flux for attracting the armature to the flange portion when it is supplied with current. The flange portion is...

Beschreibung
Zusammenfassung:	An electromagnetic clutch comprises a clutch rotor having a flange portion, an armature opposed to the flange portion, and a ring exciting coil. The ring exciting coil generates a magnetic flux for attracting the armature to the flange portion when it is supplied with current. The flange portion is formed having outside slits and inside slits. A magnetic pole portion on the outer peripheral side and a magnetic pole portion on the inner peripheral side are formed between the outside slits and the inside slits. A step portion and a concave surface continuous with the step portion are formed in a region corresponding to the magnetic pole portion on the outer peripheral side. The step portion serves to restrain the magnetic pole portion from touching the armature when the magnetic flux is formed.
