An axial flux electric motor includes a yokeless stator with a circular array of teeth, each wound with coils of electric wire generating a magnetic field parallel to the motor's rotation axis upon energization. The motor comprises first and second rotors, each having multiple permanent magnets. The first rotor is positioned above the stator with a first air gap, and the second rotor is below the stator with a second air gap. Each rotor has an adjacent circular steel back-iron plate providing a magnetic flux return path for the stator's magnetic field, covering the permanent magnets. A motor assembly structurally integrates the yokeless stator, both rotors, and back-irons, configured either with connections on both sides to a cycloid transmission or comprising thermally conductive epoxy. The axial length of this compact motor assembly may be less than 20 mm, enabling use in lightweight, space-constrained applications such as exosuits.
An exosuit comprising:
The axial flux electric motor of claim 12, wherein a wire fill factor of the yokeless stator is greater than 85%.
An axial flux electric motor comprising:
