Engine driven by magnetic force

Abstract

An engine driven by magnetic force relates to the technical field of engines. According to the technical scheme, the engine comprises a shell, a rotating shaft rotationally connected to the shell, a rotor arranged on the rotating shaft, a plurality of permanent magnets arranged on the rotor and uniformly arranged around the rotating shaft, a plurality of magnetic bases arranged on the shell and uniformly arranged around the rotating shaft, and a driving device used for driving each magnetic base to be periodically opened and closed, wherein the magnetic poles, far away from the rotating shaft, of the plurality of permanent magnets are same magnetic poles. In the operation process, the rotor is directly driven to rotate through magnetic force, and magnetic energy is converted into mechanical energy and output. Compared with an existing motor, there is no conductive equipment such as a coil and an electric brush, current changes cannot be generated, the problem of electromagnetic interference caused by the current changes is solved, and the motor is suitable for electronic equipment sensitive to the electromagnetic interference.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular to an engine driven by magnetic force. Background technique [0002] At present, there are generally electromagnetic interference problems caused by current changes in electric motors, mainly due to several reasons. One is that when the current in the winding is cut off, the magnetic field suddenly disappears, causing a transient overvoltage of hundreds of volts or even thousands of volts on the winding coil, which can lead to great energy discharge and impact other electronic devices in the loop , causing damage; the second is that for brushed motors, spark discharges are generated between the brushes and the commutator segments, and at the same time cause noise with a very wide spectrum, which is in a wide range of radio broadcasts, televisions and various electronic equipment. The third is that the motors in many electronic products use DC power rectified by bridge recti...

AI Technical Summary

Problems solved by technology

One is that when the current in the winding is cut off, the magnetic field suddenly disappears, causing a transient overvoltage of hundreds of volts or even thousands of volts to be generated on the winding coil, which can cause a huge energy discharge and have an impact on other electronic devices in the circuit , causing damage; the second is that for brush motors, spark discharges are generated between the brushes and the commutator, and at the same time cause noise with a very wide spectrum, which affects wireless broadcasting, television and various electronic equipment in a wide range The third is that the motors in many electronic products use bridge rectification and capacitor filter circuits to rectify the DC power supply, which generates very rich high-order harmonics, which not only causes serious pollution to the power grid, but also affects other uses Interference with electrical equipment

Electromagnetic interference cannot be completely eliminated. Only damping, filtering, shielding and other measures can be used to minimize the electromagnetic interference caused by the motor to the equipment and system work. However, in some sensitive electronic equipment, despite the elimination measures, the electromagnetic interference of the motor Interference can still have bad effects

There are currently no motors driven by magnetic force on the market
