Abstract
A non-mechanical differential coaxial counter-rotating power device () includes an inner shaft (), an outer shaft (), a reluctance rotor (), a permanent magnet rotor (), a stator () and a driving device (). The outer shaft () is fitted over the inner shaft (), an end of the inner shaft () protruding from the outer shaft (). The reluctance rotor () is connected to one of the end of the inner shaft () and an end of the outer shaft (), and the permanent magnet rotor () is connected to the other one of the end of the inner shaft () and the end of the outer shaft (). The stator () is coaxially disposed with the reluctance rotor () and disposed at an inner side or an outer side of the reluctance rotor () opposite to the permanent magnet rotor (). The stator () includes a stator core () and a main winding () and an auxiliary winding (), and the main winding and the auxiliary winding are wound around the stator core (). The driving device () is connected to the main winding () and the auxiliary winding () to drive the main winding () and the auxiliary winding (), respectively.
