High-torque high-rotating-speed serially excited motor

Abstract

A high-torque and high-speed series-excited motor disclosed in the present invention comprises a rotor whose two ends are respectively connected to the front bracket and the rear bracket through ball bearings, and a stator core with stator insulation slot paper inside and sleeved on the rotor. The rotor is provided with a rotor core, the stator core is provided with a stator coil, the rear end of the rotor is provided with a rear fan located outside the rear bracket; the rear bracket is provided with a commutator, the rear bracket and the commutator There are O-rings, mounting seats, plastic gaskets, wave gaskets, and spacers respectively; the rear bracket is equipped with carbon brushes corresponding to the commutator, and the carbon brushes are fixed on the carbon brush sleeves through copper sleeves. The carbon brush cover is fixed on the side wall of the rear bracket by rivets, and the side wall of the rear bracket is provided with springs, capacitors, and connecting electrodes; the front fan is arranged in the front bracket, and the front bracket, stator core and rear The brackets are fixedly connected by spring washers and screws. The motor has the characteristics of convenient installation, large starting torque, wide range of speed regulation, fast heat dissipation and low noise.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-torque and high-rotational speed series excitation motor. Background technique [0002] With the improvement of the quality of life, people began to pursue a nutritious and healthy taste of life. Juicers can meet people's demand for advocating individual tastes, and are more and more popular. The motors of juice extractors mostly use series motors. The current mixer motors are complicated to install and have high noise. Moreover, the temperature of the motors is high during use, and it will also produce peculiar smells. People hope to reduce noise pollution while extracting juice, which is safe and tasteless. However, ordinary series motors obtain high torque through high speed, and high speed will inevitably bring large jitter and high noise. Although the induction motor runs smoothly, its cost is high, its efficiency is low, its structure is complex, and its speed regu...

Problems solved by technology

However, ordinary series motors use high speed in exchange for large torque, and high speed will inevitably bring large jitter and high noise

Although the induction motor runs smoothly, its cost is high, its efficiency is low, its structure is complicated, and its speed regulation is difficult, so it is difficult to use it in a juice extractor.
