摘要： Disclosed is an outer rotor type induction motor. The present invention includes a driving shaft, a stator core fixed to a frame and having a plurality of stator slots so that the driving shaft penetrates a center of the stator core, a coil wound on the stator slots so as to form a rotatory magnetic field, a rotor housing installed outside the stator core so as to maintain a predetermined slit with the stator core wherein the driving shaft is coupled through a bottom center of the rotor housing, a rotor conductor coupled with an inner circumference face of the rotor housing so as to generate a torque by the rotatory magnetic field of the coil, and a plurality of upper blades installed at an upper end of the rotor housing so as to leave a predetermined interval therebetween wherein an external air is forcibly sucked in to cool the coil when the rotor housing revolves. The present invention secures sufficiently the space for coil winding to provide automation of winding the coil on the stator core, thereby enabling mass production to reduce product cost.

摘要： An axial flux induction motor containing both laminates and soft magnetic composite materials is described. By combining these two materials, the axial flux induction motor obtains a limited volumetric space, including a limited height, and smooth torque output, including a limited ripple. The axial flux induction motor also contains rotors bars that are skewed. These skewed bars smooth the torque pulsations of the induction motor, enhancing an efficient operation of the motor.

摘要： A superconductor motor operates as a squirrel cage induction motor. The rotor is covered with a thin film of superconducting material and the magnetic field created by the stator is strong enough to quench the superconducting material to its normal state at periodic spots on the rotor. This periodic quenching both creates a squirrel cage configuration of superconducting material on the rotor and allows the stator field to penetrate the rotor to induce a current. Once the squirrel cage is nullcreatednull by the stator field and a current induced, the motor operates as a conventional squirrel cage induction motor.

摘要： The invention relates to an electric motor, comprising a rotor (1). One side of said rotor (1) is mounted in a stator (3) by means of a bearing (2) and the rotor tapers away conically from said stator in an axial direction, forming an air gap (4) between the latter (3) and the rotor. The width of said gap increases in an axial direction, moving away from the bearing (2). The aim of the invention is to achieve improved operating efficiency using a conically designed rotor. To this end, the rotor (1) has a number of axially extending grooves (7) in a magnetically conductive material (5), in which electric conductors are placed and the difference between the maximum value and the minimum value of the thickness of a cover (8) of the grooves (7) through the magnetically conductive material of the rotor (1) in a radial direction between the end of a groove (9) lying at the outer radius and a peripheral surface (10) of the rotor (1), is less than in the case of a thickness of the cover (8) which continuously diminishes in an axial direction away from the bearing (2).
