AC series excitation motor

Abstract

An AC series motor, comprising a front bracket, a rear bracket, a stator, a rotor, a rotating shaft, fan blades and a reversing device; the stator is installed between the front bracket and the rear bracket, the rotor is located in the stator, and its center The rotating shaft is installed at the shaft position; the fan blade is installed on the end of the rotating shaft close to the rear bracket, and the reversing device is installed on the rotating shaft and is located between the rotor and the rear bracket; the The reversing device includes a commutator and two carbon brushes; the commutator is installed on the rotating shaft and is composed of multiple commutating segments, and its shape is circular; the two carbon brushes are installed on the The stator is in sliding contact with the two commutation segments respectively, and the motor is commutated by using the electromagnetic principle. The AC series motor has good commutation performance and high power, and can be well applied in a wall-breaking cooking machine to achieve a good wall-breaking effect.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an AC series motor. Background technique [0002] The wall-breaking cooking machine can instantly break the cell walls of fruits and vegetables by using its high speed, helping people to deeply condition the food, so that people's bodies can better accept and absorb more nutrients. In order to achieve a better wall-breaking effect, the load speed of the motor should be 16000-30000 rpm, so that the motor has high power and high speed technical requirements. The technical level of the motor will be used as an important indicator to measure the broken wall cooking machine. However, high-power and high-speed motors have higher requirements on the performance index of commutation, and the commutation performance of the motor affects the running state and service life of the motor. At present, the AC series motors on the market have low commutation performance and low power, which can...
