Radial winding stator structure for single phase motor
First Claim
1. A radial winding stator structure for a single phase motor, the radial winding stator structure being composed of a plurality of silicon steel sheets that are stacked together, each of the silicon steel sheets comprising:
- a hub; and
a plurality of poles numbering six or eight, each of which being radially extended from a circumference of the hub to form a radially extended portion, and tangentially expanded at a terminal of the radially extended portion to form a tangentially extended portion;
wherein the hub and the poles are one-piecemade, the radially extended portions of each of the poles are stacked to form a pole bobbin of the radial winding stator structure, the tangentially extended portions of each of the poles are stacked to form a pole surface of the radial winding stator structure, an electrically conductive wire is wound around all of the pole bobbins, and a ratio of an arc length of the pole surface to an axial height of the pole surface substantially ranges from 0.8 to 2.

Abstract
A radial winding stator structure for a single phase motor is composed of plural silicon steel sheets that are stacked together and have the same structure. Each of the silicon steel sheets includes a hub and six poles. Each pole is radially extended from a circumference of the hub to form a radially extended portion, and tangentially expanded at a terminal of the radially extended portion to form a tangentially extended portion. The hub and the poles are one-piece made, the radially extended portions of each of the poles are stacked to form a pole bobbin of the radial winding stator structure, the tangentially extended portions of each of the poles are stacked to form a pole surface of the radial winding stator structure, and an electrically conductive wire is wound around all of the pole bobbins.
