FIELD CORE
Document Type and Number:
WIPO Patent Application WO/1988/005958
Kind Code:
A1
Abstract:
Field core used for an electromagnetic clutch. A conventional field core has a bottomed cylindrical body and, therefore, manufacturing such a field core is troublesome and uneconomical. When a hole through which as shaft is inserted is provided in one or both of the vertical walls of a U-shaped plate, a field core can be obtained simply. This method can provide an inexpensive field core.
