Internally-wound stator for preventing high-voltage electric leakage

Abstract

The invention discloses an internally-wound stator for preventing high-voltage electric leakage. The internally-wound stator comprises an iron core. The iron core is formed by stacking a plurality ofidentical metal ring sheets. The iron core is provided with a plurality of winding holes distributed in an annular array around the axis of the iron core, and a winding post is formed between every two adjacent winding holes. Alower sheath is arranged below the iron core. The lower sheath comprises a lower protection piece attached to the lower end face of the iron core. A lower wire passing holecorresponding to the winding hole is formed in the lower protection piece. A lower sleeve which extends vertically and upwards and extends into the winding hole is arranged on the lower wire passing hole. A lower wire passing gap is formed in the lower sleeve. An upper sheath is arranged above the iron core. The upper sheath comprises an upper protection sheet attached to the upper end surface ofthe iron core. The upper protection sheet is provided with an upper wire passing hole corresponding to the winding hole. The upper wire passing hole is provided with an upper sleeve which vertically extends downwards and is used for extending into the winding hole. The upper sleeve is provided with an upper wire passing gap. Theinternally-wound stator has the characteristics of easiness in winding, electric leakage prevention and high safety.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, more specifically, it relates to an inner winding stator for preventing high voltage leakage. Background technique [0002] The existing stators used for motors mostly adopt an inner winding structure, which has high winding efficiency and is convenient for winding. However, this type of inner-wound stator is prone to leakage after the coil is energized, and the coil is not easy to fix, which is poor in use, high in risk, and poor in overall effect. Accordingly, the present invention proposes an inner winding stator for preventing high voltage leakage. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an inner-wound stator that prevents high-voltage leakage. The inner-wound stator has the characteristics of easy winding, anti-leakage and high safety. [0004] In order to solve the ab...
