Permanent magnet piston motor

Abstract

The invention discloses a permanent magnet piston motor, which belongs to the field of energy-saving motor development. The permanent magnet piston motor mainly comprises main components, such as an enclosure, coil cylinder bodies, permanent magnet pistons, linear bearings, signal panels, Hall elements, crankshaft connecting rods and the like, wherein the enclosure is divided into two square cavities; each cavity is provided with one coil cylinder body; the permanent magnet pistons enable upper sliding rods to be penetrated into slideways of the linear bearings by the coil cylinder bodies; the lower parts the permanent magnet pistons are in rotating connection with crankshafts by the connecting rods; the linear bearings and the upper covers are bolted; the crankshafts and the signal panels are installed on the lower part of the enclosure; the Hall elements are installed on the enclosure and correspond to the signal panels; the permanent magnet pistons do work in one stroke in the coil cylinder bodies; and the two pistons alternatively do work. According to the permanent magnet piston motor, a strong and dense space magnetic field in coils is utilized to positively act with the permanent magnet pistons, and the obtained power effect is unreachable for the traditional motor. The permanent magnet piston motor has simple construction, is easy to manufacture, is mainly applied to the field of the electric vehicle, and has a function of innovating and upgrading.

Description

technical field [0001] The invention belongs to the field of energy-saving motor development, in particular to a permanent magnet piston motor of a permanent magnet linear motor. Background technique [0002] In recent years, with the rapid development of the automobile consumption market, the number of automobiles in my country has increased exponentially, and the air pollution in large cities in my country can no longer be ignored. At this stage, China is already facing the severe challenge of oil shortage. Substitution should be related to transportation. If the number (increment) of automobiles cannot be reduced, then the oil substitution of automobile fuel will be one of the most important aspects in reducing my country's dependence on foreign oil. Judging from the current situation and expectation of import dependence, my country's energy security will become increasingly fragile, and automobile fuel substitution is an urgent issue. Therefore, the electric vehicle strat...
