FIELD: engines and pumps.
SUBSTANCE: present invention relates to electrical engineering, namely to electric machines manufacture. The motor coil frame comprises the main part of the coil frame, around which the coil is to be wound, and flanged portions formed integrally with both end portions of the main part of the coil frame, wherein the coil frame uncludes a resin-based molded part formed using a polymer with amide linkages and insulating aramid containing paper made from aramid fibrid and short aramid fibers, at that, the surface of the resin-based molded part and of aramid paper are directly connected to each other.
EFFECT: invention provides improved performance and power output of electrical machines.
