Slotless rotating electric machine

The slotless rotating electric machine comprising:

• a rotor having multiple alternating polarity permanent magnets that drive magnetic flux back and forth across a magnetic airgap formed with an airgap surface of a slotless ferromagnetic stator;
• said slotless ferromagnetic stator comprising a stator backiron ring formed from ferromagnetic material and an adhesive film on said airgap surface of said stator backiron ring;
• armature windings of wire adhered to said adhesive film on said airgap surface wherein said wire comprises individually insulated twisted strands;
• said armature windings comprising an air core winding pattern formed directly onto said adhesive film;
• said armature windings pressured against said stator backiron ring as a group after formed and adhered with heat, imparting said armature windings to be secured in said air core winding pattern formed on said airgap surface, and additionally with said adhesive film flowed partially up a sides of said wire in a direction away from said stator backiron ring and towards said rotor at locations inside said magnetic airgap;
• said adhesive film providing increased resistance to force on said armature windings.

A slotless rotating electric machine comprising:

• a rotor having multiple poles that drive magnetic flux across a magnetic airgap formed with a radial airgap surface of a slotless ferromagnetic stator;
• a slotless ferromagnetic stator formed as a helical stator backiron of a ferromagnetic strip wound edgewise and extending axially;
• an adhesive film on said radial airgap surface of said helical stator backiron;
• armature windings of wire adhered to said adhesive film on said radial airgap surface wherein said wire comprises individually insulated twisted strands diametrically enveloped by an outer serve;
• said adhesive film holding said serve to said helical stator backiron with said serve holding said strands to said adhesive film;
• said armature windings applied in an air core winding pattern onto said adhesive film in a one wire radial layer that is only one wire deep where inside said magnetic airgap, and with end turns of multiple phases overlapping;
• said air core winding pattern secured to said helical stator backiron on said radial airgap surface and additionally by said adhesive film flowed partially up the sides of said wire in a direction away from said helical stator backiron and towards said rotor at locations inside said magnetic airgap, not including the side of said wire facing the rotor opposite said radial airgap surface of said helical stator backiron;
• said flowed adhesive imparting increased resistance to force on said armature windings.
