Novel flat single-phase quadrupole series excited motor

Abstract

The invention discloses a novel flat single-phase quadrupole series excited motor in the technical field of household food mixing machines. The novel flat single-phase quadrupole series excited motor comprises a brush carrier plate, wherein electric brush assemblies are clamped at four corners of the top part of the brush carrier plate, the four electric brush assemblies are distributed at the top part of the brush carrier plate in a surrounding array manner, the top part of the brush carrier plate is fixedly connected with four annular partition plates through bolts, and the four annular partition plates are located between every two electric brush assemblies. The novel flat single-phase four-pole series excited motor is reasonable in structural design, heat generated in the operation process of the motor can be taken away more easily in the operation process, components in the equipment are fundamentally prevented from being damaged due to the influence of high temperature, the connection between the carbon powder and a rear bracket main body is further fundamentally disconnected, the formation of a conductive path is avoided, and the direct contact between an enameled wire and a metal shaft is effectively avoided, so that the phenomenon of high-voltage breakdown is prevented, and the rotating speed of the motor can be detected at the same time.

Description

technical field [0001] The invention relates to the technical field of household food mixers, in particular to a novel flat single-phase four-pole series motor. Background technique [0002] As one of the commonly used equipment in the home kitchen, the household food mixer is a small-scale machine that realizes the mixing and processing of various fruits and vegetables, so that the food can be broken repeatedly under the action of water flow, so as to squeeze out fresh and delicious fruit juice and vegetable juice. Machines usually use brushless DC motors as their main driving devices, but due to the high cost of brushless DC motors, it is not conducive to market competition, while single-phase series motors are mature in technology, low in cost and easy to produce, and are used as the driving device of household mixers. Emerging choice. [0003] In the existing market, single-phase four-pole series motors are usually used as the driving device for household food mixers, b...

Problems solved by technology

[0009] The purpose of the present invention is to provide a new flat single-phase four-pole series motor to solve the problem that the motor will generate high temperature during operation in the above background technology, but the traditional equipment does not have effective heat dissipation effect, which makes the motor vulnerable to high temperature Affect and damage its internal components, the motor will produce carbon powder during operation, and it will easily form a conductive path between the long-term accumulation on the brush holder plate and the main body of the metal rear bracket, resulting in a short circuit, which is easy to occur during the winding process. The contact between the enameled wire and the metal shaft causes current breakdown and short circuit. The traditional motor does not have the function of detecting its speed, which leads to the problem that the use efficiency of the equipment cannot meet the actual use effect.
