The paper discusses one of the design stages of an electrical complex of a linear motor of a low-speed long-stroke piston compressor based on a permanent magnet synchronous motor (SMPM). The article concernswith studying the thermal regime of the magnetic system. The temperature regime up to 80 0 Cis the limitation for the use of permanent magnets of the N40 series based on the NdFeB alloy, consequently the problem of determining the amount of heat released by the winding is urgent. To study the thermal regime, a prototype of a linear permanent magnet motor was developed and tested with a long-term current flow of 5 A. The efficiency of using a sectioned winding divided into eight coils especially whenthe coils switchedin two pairs is shown.
