摘要： An axial air gap type electric motor realizes a torque up without an increase of the size of the electric motor. In the axial air gap type electric motor including a stator and two rotors each of which is molded almost with a discoid shape and which are arranged as facing one another on a common rotation axle with a fixed gap therebetween, the stator has a stator core including 3n (n indicates an integer of 2 or higher) pole members, and the pole members with three-phase configuration are connected in parallel. The rotors are formed with multiple magnets molded like a ring at an equal interval at positions facing the annular stator core when facing the stator, and the ratio of the number of the pole members and the number of the magnets becomes 3n:4n (wherein n indicates an integer of 2 or higher).

摘要： Disclosed are a single rotor-type axial gap motor with low magnetic loss and high output, and a pump device using the axial gap motor. A first contact surface (231) is provided on the lateral surface in one circumferential direction of a yoke strip (23), and a second contact surface (232) is provided on the lateral surface in the other circumferential direction of the yoke strip (23), wherein the first contact surface (231) and the second contact surface (232) are aligned with each other. Defining As1 and As2 as the surface areas (As) of the first and second contact surfaces (231, 232), and Ap1 and Ap2 as the projected surface areas (Ap) of the lateral surfaces of the aforementioned yoke strip seen from the circumferential direction, it holds that As>Ap.

摘要： An axial air gap type electric motor is constructed such that even if a relatively large force is added in the vertical direction to the rotor output, the bearings are protected against damage. The axial air gap type electric motor includes a stator and two rotors each of which is configured almost with a discoid shape and which are arranged as facing one another on a common rotation axle with a fixed gap being present therebetween. The stator has a stator core comprising multiple pole members connected annularly. One of the bearings for fixing the rotor output axle is installed inside the stator configured annularly and another bearing is installed on the rotor output axle between the outside of said rotor and the load connected.
