An air-core pulsed alternator is made of nonferromagnetic materials, which needs very high field current. Self-excitation is usually applied in these systems. This is a positive-feedback progress, which takes tens of milliseconds to reach the desired large field current. The field loss is one of the main limitations of the machine design. This paper presents a new excitation mode, which is the pulse-excitation...
An air-core compulsator is a special synchronous alternator which is made of nonferromagnetic material instead of traditional ferromagnetic material. The method of magnetic field calculation and analysis is different from that of the traditional machines. In this paper, an analytical method used to calculate the magnetic field of the air-core compulsator has been presented. The result calculated by...
