Electromagnetic rotating device

Abstract

The invention discloses an electromagnetic rotating device which comprises a first component and a second component. The first component comprises a driving shaft and a first permanent magnet, and the first permanent magnet is distributed on the periphery of the driving shaft. The second component comprises a coil, a pole shoe and a second permanent magnet. The coil is wound on the pole shoe, and magnetic poles of the second permanent magnet and the first permanent magnet have an included angle. When positive or negative pulse current flows in the coil, attracted or repellent acting force is generated between the first permanent magnet and the second permanent magnet, and the first component and the second component move relatively. By changing the geometric shapes and the magnetic field direction of the permanent magnets and by means of the characteristics of mutual attraction or repulsion between the permanent magnets and mutual attraction and repulsion between a pulse type electromagnetic field and the permanent magnets, the problem that current is not required to be exerted continuously during reciprocating rotation is solved, and a large amount of working current is not required to be led to the coil for a long time.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, in particular to a magnetoelectric rotating device. Background technique [0002] At present, most of the products that need to be driven by rotation adopt three methods. The first is to use a coil to drive the iron core for linear motion (such as some air disc valve products). The iron core is equipped with a connecting rod, and a rack is installed on the connecting rod. The rack drives the gear, and the rotation of the gear is determined by the movement direction of the rack; 2 is the motor drives the cam, etc. (such as some reciprocating switch products); 3 is the motor drive (such as electric valves, etc.), but no matter which way , all require that the coil must be in a long-term working state, so that the working current forming the electromagnetic field must pass through the coil continuously. Under the long-term working state, the coil heating and burning are ine...
