摘要：
The invention relates to a device for phase compensation and excitation of a multiphase asynchronous machine, especially one to be driven as a generator and to be operated at low speed. Each winding (1 to 3) in the machine is connected in series or in parallel with a capacitive element consisting of a bank of capacitors (4 to 6) having at least one pair of series connected electrolytic capacitors (7, 8), having in each pair equal terminals interconnected.
