| description | The invention relates to a high power density disc motor which is characterized in that a soft magnet constitutes a flat ring stator core; a wire groove with a fan-shaped surface is arranged on the end surface thereof; the width of the outer circle end of the fan-shaped wire groove is larger than the width of the inner circle end; and the groove depth of the inner circle end of the wire groove is larger than the groove depth of the outer circle end. A stator core of the motor adopts the soft magnet with, the performance equal to a silicon steel sheet winding stator core with high magnetic permeability; the area of an outer circle yoke part of the stator core is larger than the area of an inner circle yoke part; the material is fully utilized; the effective magnetic lines of force of the yokes can be increased by about 50 percent; the groove area can be increased by about 30 percent; and the power output of the motor can be increased, thereby forming the high power density disc motor.
