In high-frequency operating environments, soft magnetic composite materials generally outperform traditional laminated cores due to lower eddy current losses; however, in low-frequency, high-power applications, silicon steel sheets still retain certain advantages. In practice, the choice should be evaluated based on the motor's operating frequency and application scenario.
Yes. Through material formulation adjustment and density control, PM gearbox components can achieve excellent wear resistance and dimensional stability, and are widely used in the long-duration operating environments of home appliances and industrial motors.
Yes. The design flexibility of three-dimensional magnetic circuits in soft magnetic composite materials helps reduce eddy current losses and improve energy conversion efficiency, and is one of the technical approaches many motor manufacturers use to achieve higher efficiency classes such as IE3 and IE4.
