Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0031] It should be noted that if there are directional indications involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.
[0032] In addition, if there are descriptions involving "first", "second" and so o...

The invention discloses a radial flux permanent magnet type direct current motor. The electromagnetic driving structure comprises a magnetic tile assembly and a coil assembly, wherein an annular magnetic tile ring is formed on the magnetic tile assembly, and is provided with two opposite magnetic poles which are distributed inwards and outwards, a driving magnetic field is formed between the two magnetic poles, a coil winding ring is formed on the coil assembly, the coil winding ring and the annular magnetic tile ring are nested inside and outside, the coil winding ring is provided with an annular center line, magnetic induction lines distributed along the annular center line are formed on the coil winding ring, the magnetic induction lines and the driving magnetic field act together to enable the coil assembly and the magnetic tile assembly to rotate relatively, one of the magnetic tile assembly and the coil assembly is arranged on a motor shell, and the other one is arranged on a rotating shaft. According to the invention, in a moving process, the direction of the magnetic field is not changed, under the condition that the direction of the current is not changed, the electrifiedcoil assembly can continuously rotate in the fixed direction, and a commutator is not needed for reversing, so that it is avoided that electromagnetic radiation generated in the reversing process of the commutator affects other electronic devices.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a radial flux permanent magnet DC motor. Background technique [0002] Permanent magnet DC motor is a kind of DC motor that uses permanent magnets to establish a magnetic field, and is widely used in all walks of life in modern industry. In the existing technical solution, the energized coil is forced in the magnetic field, and the direction of the current is switched through the commutator, so that the coil can continue to rotate. The current in the motor armature must be commutated through the commutator. Electromagnetic radiation, affecting other electronic equipment. Contents of the invention [0003] The main purpose of the present invention is to propose a radial flux permanent magnet DC motor, which aims to solve the problem that the current permanent magnet DC motor generates electromagnetic radiation when it relies on a commutator for commutation and affects other elec...
