Abstract
A mode that an electric solenoid is used for generating a magnetic field has the disadvantages of high power consumption and larger size, and large current is frequently needed to generate a large magnetic field. The utility model provides a magnetic field generating device which comprises two soft magnet cores, a solenoid, a rotating magnetic field area, a permanent magnet and a magnetizer, wherein the solenoid is wound on the two soft magnet cores, the circular rotating magnetic field area is formed between the two soft magnet cores, the permanent magnet is installed in the rotating magnetic field area and connected with a stepping motor, the magnetizer is connected with the soft magnet cores, and a gap is formed in the middle of the magnetizer. According to the magnetic field generating device, the permanent magnet is rotated to a certain angle, the permanent magnet and the soft magnet cores are coupled to generate the magnetic field, and the large magnetic field can be generated; the magnetic field generating device has the advantages of convenience in adjustment, low power consumption, small size and convenience in use; and additionally, the magnetic field can be superimposed through the solenoid.
Description
Technical field
The utility model relates to the electromagnetic device field, refers more particularly to a kind of device that produces magnetic field.
Background technology
The importance in magnetic field is self-evident, and the earth itself is exactly a magnet, utilizes the magnetic field of the earth, can realize navigation, location etc., in fields such as military affairs, daily lifes important effect is arranged.In general, people produce magnetic field by the mode of energization solenoid, it is advantageous that the magnetic field size is easy to regulation and control, but the power consumption height, producing big magnetic field often needs very big, electric current, and simultaneously, volume is often also bigger.
The utility model content
At existing problem, the utility model provides a kind of device that produces magnetic field, can produce big magnetic field, and is easy to adjust, and the while is low in energy consumption, volume is little.To achieve these goals, technical solution adopted in the utility model is, a kind of device that produces magnetic field, comprise soft magnet core, solenoid, rotating magnetic field district, permanent magnet, magnetic conductor, wherein, solenoid forms circular rotating magnetic field district in the middle of two soft magnet cores on two soft magnet cores, permanent magnet is installed in the rotating magnetic field district, and permanent magnet is connected with stepping motor; Magnetic conductor is connected with soft magnet core, forms the space in the middle of the magnetic conductor.
The utility model arrives certain angle by rotating permanent magnet, coupling by permanent magnet and soft magnet core produces magnetic field, because the magnetic field of permanent magnet is big, can produce big magnetic field, control by stepping motor, easy to adjust, low in energy consumption, volume is also little simultaneously, in addition, can carry out the stack in magnetic field by solenoid, use, convenience very.
