Abstract

An electrical machine including a moveable permanent magnet configured to generate a first magnetic field. A stator including windings configured to excite a second magnetic field. A moveable inter-pole component located between the permanent magnet component and the stator, the inter-pole component comprising an array of magnetic inter-pole pieces. The speed of movement of the inter-pole component is controlled to set a magnetic gear ratio between the first and second magnetic fields. Also a gas turbine engine, propulsor or thruster incorporating the electrical machine.
