Due to its excellent magnetic performance, amorphous metal offers the potential of reducing the core loss of motors dramatically and improve the motor efficiency. According to the characteristics of amorphous alloy materials, based on the basic design theory of permanent magnet motor, the analytical expression of copper loss and core loss was derived. Through the expression of loss, several key design variables were emphasized: the inner-to- external diameter, the flux density, that assumed a decisive role in the permanent magnet motor. The design rules of amorphous alloy motor were summarized. On the basis of design rules, an amorphous alloy permanent magnet motor was designed and tested. The study had certain reference value for design and optimization of amorphous alloy motor.
