Effect of Magnetic Properties of Magnetic Composite Tapes on Motor Losses

Alternating current (AC) copper losses in motors increase with carrier frequency of the pulse width modulation (PWM) and are further increased by leakage flux permanent magnet. Therefore, AC motor speed. Conventional techniques for reducing tend to other losses. In this paper, loss was reduced wrapping a magnetic tape made composite material around winding. This method controlled path through Magnetic materials mixtures powders liquid resins whose properties can be manipulated changing combination factors. When Fe–Si–Al wrapped winding, 40%. The optimizing material. maximally when specific permeability 100 saturation density 1.6. tapes composed high reduce without increasing motor.
