Abstract
An axial flux electric motor includes a rotationally fixed stator defining a rotational axis and having a plurality of conductive stator magnetic poles arranged radially about the rotational axis. The electric motor also includes a rotor spaced axially from one side of the stator, rotatably mounted coaxially with the rotational axis, and having a plurality of permanent magnets (PMs) arranged symmetrically around the rotational axis and facing the stator. A torque is generated on the at least one rotor by a rotating magnetic field established via interaction between the corresponding PMs and the magnetic poles when an electrical current is passed through the magnetic poles. The stator additionally includes a plurality of cooling channel loops, together surrounding each of the stator magnetic poles, and configured to receive and pass therethrough a fluid to remove thermal energy from the stator magnetic poles resulting from an electrical current passed therethrough.
