| Synopsis: For motor core materials, Kawasaki Steel has developed new products such as 35RM200 for low iron loss, the RP series for high induction, the RMHE series for low iron loss and high induction, the RMHF series for low iron loss at high frequency, and the B-type self-adhesive type organic coating, by controlling the metallurgical factors in an optimum condition. In order to improve the brushless DC motor efficiency and torque, a decrease in high frequency iron loss and increase in flux density in the core material were found to be effective, respectively. Localized iron loss measurement in the rotating motor proved that a high iron loss occurred in the teeth. |
