OVEN FOR CONTROLLING HEATING AND CURING OF RESINOUS INSULATING MATERIAL

摘要

An oven for heating and curing a powder of heat hardenable resinous material that has been applied to the portions of coil windings in a slot of a magnetic core as well as to the coil end turns including at least two heating panels disposed at spaced distances from the coated coil windings, the panels having a plurality of infrared radiant energy sources directed towards the coil windings, the panels being movable toward and away from the position of the coil windings, and control means associated with the panels for measuring the temperature of the resinous coating on the coil windings during the heating and curing operation, which means are operatively connected to the circuit of the infrared heat sources for turning the source on and off at prescribed intervals.
