Abstract
619,058. Securing coils for dynamo-electric machines. WOOSEY, E., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 11, 1946, No. 17448. [Class 35] A slot wedge is composed of metal laminµ 14 mutually insulated at 15 and secured together by an adhesive in planes transverse to the direction of the slot. Non-magnetic metals, e.g. aluminium or brass or alloys thereof may be used and fabric reinforced insulating materials, e.g. thermosetting synthetic resins or rubber may be used to insulate and secure the laminµ. The laminµ may be blanked out separately from a strip of metal to which an insulating covering has been applied, or several laminµ of the form shown in Fig. 4 may be fixed together and parted along the grooves to separate the individual wedges, insulating material preferably being applied to the sides of the wedges. Alternatively, this form of blank may be wound onto a square mandrel and then cut into separate wedges after moulding. In a further method the insulated strip is folded up concertina-wise to form the strip.
