Abstract
A wobble plate motor includes a wobble plate and a stator. The wobble plate is made of magnetically susceptible material and has a wobble axis. The stator includes a permanent magnet and a set of electromagnetic coils and has a stator axis. The wobble plate is configured to nutate around the stator with the wobble axis precessing around the stator axis. The wobble plate has a mobile point of closest approach with respect to the stator. The mobile point of closest approach moves around the stator axis as the wobble plate nutates. The permanent magnet and the set of electromagnetic coils are configured to create a magnetic field having a flux density between the stator and the wobble plate with a highest flux density at a mobile location ahead of the mobile point of closest approach in an angular direction around the stator axis as the wobble plate nutates.
