BULK METALLIC GLASS MOTOR AND TRANSFORMER PARTS AND METHOD OF MANUFACTURE

摘要

The invention relates to a method of bonding together metallic glass laminations to form a stack and thereafter shaping the stack, e.g. by cutting to form a bulk object, e.g. a wound stator of an electric motor. The method involves coating individual laminations of metallic glass with a temperature resistant, non-gas producing metal bonding agent, stacking the coated laminations, applying a pressure to the stacked laminations such that the bonding agent does not exude from between the laminations, allowing the bonding agent to cure, and thereafter shaping the stacked laminations as required. In some cases, temperature resistant wiring and insulation are fitted to the shaped laminations and heated to a temperature sufficient to anneal the metallic glass. The laminations are shaped by cutting with a mixture of fluent material and abrasive material emitted from a nozzle at high pressure. The laminations or the nozzle are adjustable such that the outer surface of the cutting mixture is perpendicular to the plane of the surface of the laminations.
