Rotor for printed-wiring motor

摘要

A rotor for printed-wiring motors includes a flat disk-like non-iron armature mounted on a hub secured to a rotating shaft, the armature being composed of at least two sheet coil assemblies bonded together under heat and pressure with a first thin insulating disc disposed therebetween. Each of the sheet coil assemblies is composed of a pair of sheet coils bonded together under heat and pressure with a second thin insulating disc disposed therebetween. Both the first and second insulating disc are formed of a web of aramid fiber coated with an insulating bonded adhesive.
