Abstract. Depending on the purpose and dimensions of the machine, the design of the stator of a synchronous machine can be different. For example, in powerful multi-pole machines, when the outer diameter of the stator magnetic circuit is 900 mm or more, the magnetic circuit plates are made of separate segments and, after assembly, form a magnetic circuit cylinder. For ease of transportation and installation, stator housings of large-sized machines are manufactured in prefabricated form.
