In order to increasing the efficiency of axial gap motors, a motor was designed to achieve an efficiency of 98% based on the IE 5–11 kW motor (motor efficiency of 96%). Based on the design, we created a prototype with ceramic housings, thinned coil conductors, and nanocrystalline materials for the stator core as real items to reduce losses. We verified its effect by evaluating the motor characteristics. As a result, it was confirmed that the prototype can achieve a motor efficiency of 98.3% at 3,000 min-1 and 11 kW rated driving. Moreover, in the temperature rise test, it was demonstrated that class B type (130◦C) could be achieved.
