| 摘要 |
The present invention relates to a shaded-pole, single-phase induction motor, which can be converted to a permanent magnet motor, of the type that includes a front casing, a stator element, a rotor element, a plurality of windings arranged on the salient poles of the stator element and a rear casing, wherein the stator element has a square configuration in which the four salient poles are rotated by 45º relative to the axes of horizontal and vertical symmetry such as to be aligned with the four corners of the stator element. The novel configuration of the stator enables the use of laminating material to be optimised during the production and assembly of the sheet packets of the stator element and the rotor element; in addition, since the salient poles are rotated by 45º in the stator element, the electric loss in the windings thereof and the operating temperature are reduced, which enables the operational efficiency of the motor to be increased. Likewise, the reduction in the operating temperature of the stator element makes to use plastic materials for the components thereof possible. |
