COMPARISON OF SYNCHRONOUS HYBRID EXCITED MACHINES WITH MACHINES OF PERMANENT MAGNET AND ELECTROMAGNETIC EXCITATION
Abstract
Synchronous machines with permanent magnet and electromagnetic excitation are widely used as motors and generators in various fields of operation, depending on the tasks.Machines with electromagnetic excitation are characterized by wide adjustment properties, while machines with permanent magnetexcitation have high power-to-weight ratio, efficiency, reliability, but there is no possibility to regulate the main magnetic flux in airgap. Analysis of existing methods of control the magnetic flux, which are reviewed in national scientific sources, showed the ineffectiveness of these methods.The analysis of foreign scientific papers showed a wide interest to the machines with hybrid excitation, which are an intermediate link between the class of permanent magnet machines and machines with field excitation winding. In essence, hybrid excitation machines combine two types of excitation at the same time: excitation from permanent magnets and excitation windings.
This article presents a comparison of machines of different types of excitation, namely: an analysis of the existing serial machines of the different power range with electromagnetic, permanent magnet and hybrid excitation according to the criteria of power-to weight ratio and efficiency is carried out.The calculation of machines with hybrid excitation was carried out on the basis of well-known methods for calculating machines with permanent magnetexcitation and numerical methods for solving electromagnetic field equations. Thanks to the field analysis, a number of machines with hybrid excitation power up to 75 kW was calculated and compared with known serial machines. It has been found the expedient usage of machines with hybrid excitation while ensuring regulation of the magnetic flux up to 40% in comparison with machines of other types of excitation.
