WebThe induction machine equations are expressed in a synchronous reference frame orientated with the rotor field (SRFORF). This frame is synchronous with the stator and rotor magnetic fields, and the D-axis is aligned with the rotor field D-axis. The rotor magnetic flux linkage vector only has a D-axis component in this frame. WebJul 26, 2024 · The synchronous machine is used, essentially interchangeably, as a motor and as a generator. Note that, as a motor, this type of machine produces torque only when it is running at synchronous speed. So far, we have been describing what are referred to as …
WebSynchronous Machines • The inductance of the stator winding depends on the rotor position • Energy is stored in the inductance • As the rotor moves, there is a change in the energy stored • Either energy is extracted from the magnetic field (and becomes mechanical energy – that is, its is a motor) • Or energy is stored in the magnetic field and ...
