Energy-saving motor stator

Abstract

The invention designs an energy-saving motor stator. The energy-saving motor stator comprises a stator body and is characterized in that the stator body is composed of an inner iron core and an outer iron core which are fixed by virtue of interference fit of the outer periphery of the inner iron core and the inner periphery of the outer iron core, wherein the outer iron core is a circular ring structure; the inner periphery of the inner iron core is enclosed; the outer periphery of the inner iron core is grooved to form a radial structure from inside to outside; the grooves are wire winding grooves; and each of groove openings is provided with steps for blocking wires. According to the energy-saving motor stator designed by the invention, by virtue of the groove opening design of the inner iron core of the stator body, automatic wire winding can be conducted directly by a wire winding machine outside the stator, thereby enabling winding coils in the end part to be short, reducing the usage amount of enameled wires, reducing the winding resistance, and thus improving the motor working efficiency. At the same time, the inner periphery of the inner iron core of the stator body is an enclosed structure with a thickness of 0.2-0.6 millimeters so that the magnetic leakage between teeth of the stator can be reduced effectively and the motor efficiency can be further improved.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to an energy-saving motor stator. Background technique [0002] In the prior art, the structure of the stator of the motor is an integral structure, and slots are slotted in the inner diameter, and the slots are for the convenience of the winding machine to wind the coil. Although this method is relatively mature, it uses a large number of enameled wires, which increases the resistance of the motor, and causes a lot of heat generation and energy loss. On the other hand, due to the internal slot, the coil generates magnetic flux leakage, which also leads to energy loss. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving motor stator that can use a small number of enameled wires in the same volume to solve the shortcomings of the above-mentioned technologies, so that the final motor energy utilization rate is high.
