One-stroke intermittent power supply motor

Abstract

The invention discloses a one-stroke intermittent power supply motor, wherein the magnetic poles on both ends of electromagnets are simultaneously reciprocatingly stressed in forward direction. The motor comprises a frame, a crankshaft, a flywheel, at least one group of magnetic driving unit and at least one group of corresponding control unit, wherein the crankshaft, the flywheel, the magnetic driving unit and the corresponding control unit are arranged on the frame. The magnetic driving unit comprises a crank throw arranged on the crankshaft, a connecting rod, a telescopic shaft, two slides,N+ electromagnets (moving magnets) and N++1 permanent magnets (fixed magnets), wherein N+ is a positive integer. N++1 permanent magnets are homopolar, are opposite to each other in sequence, and arealternately arranged with N+ electromagnets. The control unit comprises a current rotating connector and a current intermittent commutator. The on / off strokes of two commutator segments and brushes ofthe current intermittent commutator respectively account for 1 / 4 of the circumference, so that the alternating of direct current direction is twice per cycle, and the electromagnets are powered on inthe start 1 / 2 stroke and are powered off in the other 1 / 2 stroke. The magnetic poles on both ends of the electromagnets and an iron core with a power-off end are forced to complete one stroke in a relay, and complete the other stroke the same. The telescopic shaft acts on the connecting rod, and the crankshaft rotates to output power.

Description

technical field [0001] The invention belongs to the technical field of electromagnetism and power machinery, and relates to a power machinery with positive magnetic field force, in particular to a one-stroke intermittent power supply motor with positive reciprocating force at both ends of an electromagnet (moving magnet). Background technique [0002] As we all know, permanent magnets have the characteristics of being magnetized once and permanently, and the same poles repel each other, and different poles attract each other. With the advancement of technology, the performance of permanent magnets continues to improve. Today's rare earth NdFeB permanent magnets Super magnetic, able to provide a continuous strong magnetic field. [0003] At present, it is known that: 1. The motor does work by generating a rotating magnetic field after the armature winding is energized, and its disadvantage is that it needs continuous power supply to work normally; 2. The name of the invention...

Problems solved by technology

[0003] At present, it is known that: 1. The motor does work by generating a rotating magnetic field after the armature winding is energized, and its disadvantage is that it needs continuous power supply to work normally; 2. The name of the invention is "Two-Stroke Permanent Magnet Motor", and the application (patent) number is 2010105520625 , The authorized announcement number is the invention patent of 102468786B. Its principle is to use the positive repulsion of the moving magnet (permanent magnet) and the fixed magnet (energized electromagnet) to complete a stroke, and use the moving magnet (permanent magnet) and the core of the power-off electromagnet The positive attraction of the moving magnet completes another stroke, and the reciprocating linear motion passes the connecting rod to rotate the crankshaft to output power. The disadvantage is that only one end of the moving magnet is stressed.
