Abstract
111,689. Sandycroft, Ltd., Cleaver, R. L., and Potts, H. E. Oct. 31, 1916. Insulation.-The slot insulation of the stator and rotor is formed by a plastic material which is moulded in position while assembling the winding and afterwards hardened or toughened so as to form a protective layer for both the coil and the slot walls. The parts of the winding outside the slot may be covered with similar insulation which may be extended to cover the whole or part of the iron of the machine. Vulcanizable rubber or bitumen (or a mixture of the two) compounded with sulphur may be used as the plastic material and may be in the form of tape, sheet, or dough. The plastic material is vulcanized by subjecting it to heat, preferably by steam under pressure. Wedges or packing pieces of ebonite or rubber or other hardened plastic material may be inserted between the coils and the sides of the slot. Where binding wire is used to secure the conductors in position the wire is embedded in the plastic material.
