An axial type flat permanent magnet motor (AFPM motor) is used for audio visual equipment, information actuators, etc. However it is limited to a small capacity with a small air gap. In this paper, the characteristics of the AFPM motor with a large air gap to protect and/or separate between the rotor and the stator for new applications are examined. The tested motor has an 8 mm air gap length and a 170 W output capacity. Maximum efficiency of the tested motor is about 80%, and if the air gap length is spread to 12 mm, the tested motor keeps 66% efficiency. Moreover, it is shown that the steady-state characteristics of the AFPM motor driven by a 6-step inverter can be estimated using d-q coordinates modeling.
