Inductive coupling in an ASM is at the drive frequency (hundreds of Hz), inductive coupling in an inductive electrically excited SM can work at an arbitrary frequency, e.g. 100 kHz. You can also see in the ZF release how small the coils for transferring the excitation current are compared to the main windings, they are the small rings on the left side. |
