Cycloidal electric machine with minimized airgap |
| abstract |
An electrical system includes a cycloidal electric machine having a stator and an eccentric rotor. An airgap is defined between the stator and the rotor. The rotor moves with two degrees of freedom (2DOF), including rotating motion about the rotor axis and orbiting motion about the stator axis. A rotor constraint mechanism (RCM) constrains rotor motion to enable output torque to transfer to a coupled load in at least one of the 2DOF. The machine includes a structural element connected to or formed integrally with the rotor or stator that minimizes and substantially equalizes a size of the airgap around a circumference of the rotor. The element may be a crescent-shaped race of ferrous material coupled to a rotor shaft. The stator may include stator teeth, the rotor may include lobes, and the stator teeth and rotor lobes may have cycloid-profiled surfaces that form the structural element. |
