FIELD: electricity.
SUBSTANCE: method for manufacture of magnet core based on amorphous alloy emitting audible noise includes placement of the core with several layers of high-strength tape at the core arms. The tape has high-tensile strength, high dielectric strength and high operating temperature, which result in reduced level of audible noise. When operated in optimal conditions the reduced level of audible noise is per 6-10 dB less than the core of the same size covered with resin.
EFFECT: reduced audible noise.
