Trial manufacture of magnetic anisotropic motor and evaluation of drag loss characteristics

A magnetic anisotropic motor, the stator core is made of grain-oriented (GO) steel plates, is manufactured as a trail, and the experimental drug force data show that the iron loss reduction is confirmed. The easy magnetization direction of divided GO steel is arranged so as to follow the main magnetic flux of the stator core in order to realize the low iron loss characteristics in the motor core. A special jig is used in manufacturing it to obtain the sufficient accuracy arrangement of the divided GO piece. The iron loss of the magnetic anisotropic motor is compared with the one of the non-oriented (NO) conventional motor.
