A rotary magnetic motor having a rotor configured to magnetically interact with a stator to obtain rotation of the rotor about its axis. The stator has a magnetic structure of a generally involute shape around the axis of rotation. The stator magnetic structure has a plurality of permanent magnets defining a first magnetic face of a first polarity. The rotor has a magnetic structure of a generally circular shape around the axis and inside the stator magnetic structure. The rotor has a plurality of permanent magnets defining a second magnetic face of a second polarity. The magnetic attraction and repulsing of the aligned magnetic faces with a progressively narrowing radial gap, resulting from the involute shape, rotate the rotor inside the stator. A magnetic pulse mechanism discharges a magnetic pulse of the first polarity to provide an additional pull to continue the rotation of the rotor through its full cycle.
