Background technology
The electromagnetism field wave that motor produces, makes space be polluted, and the electromagnetic field wave action of particularly seriously motor radiation, conduction the normal work of various electronics, electric equipment.The electromagnetic field wave interference of motor is mainly from magnetic field and the electric arc between commutator and brush of suddenling change in its winding.In brush motor, when brush is from a slice of commutator to another sheet transition, due to the sharply change of contact resistance, cause electric current to be undergone mutation and produce electric arc, form precipitous impulse electric field wave interference, in very wide frequency range, cause high frequency, very high frequency(VHF) to disturb harmonic wave, radiated interference is passed through in power line conducted interference system or system outer other electronics, electric device.So logical magnetic screen means protect electronic circuit to avoid the interference of electromagnetic field.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of commutator eliminating the interference of electromagnetic field, has that structure is simple, result of use good, can effectively reduce the electromagnetism field wave of motor, reduce motor radiation to features such as the infringements that human body causes.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of commutator eliminating the interference of electromagnetic field, comprise commutator segment, commutator pedestal and annular multi-pole magnetic sheet, described commutator segment homogeneous vertical embeds and is arranged on commutator pedestal outer ring place, described commutator segment top is arranged side by side with the hook pin I and hook pin II that all bend outwards, described hook pin I bends in 85 ° ~ 95 °, described hook pin II bends in 45 ° ~ 65 °, described hook pin I is provided with annular multi-pole magnetic sheet, described annular multi-pole magnetic sheet comprises ring-shaped cylinder magnetic sheet and copper sheet, described copper sheet evenly embeds and is arranged on ring-shaped cylinder magnetic sheet surface, by the annular multi-pole magnetic sheet installed, the electromagnetic field of commutator is eliminated, number of poles on annular multi-pole magnetic sheet is identical with the number of poles of commutator, make electromagnetic field disturbed and cannot produce.
Supplement as to the one of technical scheme described in the utility model, described commutator segment is strip, its vertical plane one middle side part is furnished with mounting groove, described commutator segment Upper vertical is arranged side by side vertical bar I and vertical bar II, described vertical bar II is higher than vertical bar I, by arranging mounting groove, more stable when being commutator segment embedding installation, by arranging vertical bar I and vertical bar II, make it can bend in hook pin I and hook pin II.
Supplement as to the one of technical scheme described in the utility model, described annular multi-pole magnetic sheet is welded on the hook pin I arranged ringwise, adopts welding, annular multi-pole magnetic sheet is installed more stable.
Supplement as to the one of technical scheme described in the utility model, described commutator pedestal is suppressed in cylindric by phenolic moulding powder high temperature.
beneficial effect
The utility model relates to a kind of commutator eliminating the interference of electromagnetic field, by the annular multi-pole magnetic sheet installed, the electromagnetic field of commutator is eliminated, number of poles on annular multi-pole magnetic sheet is identical with the number of poles of commutator, make electromagnetic field disturbed and cannot produce, by arranging mounting groove, more stable when being commutator segment embedding installation, by arranging vertical bar I and vertical bar II, make it can bend in hook pin I and hook pin II, adopt welded and installed annular multi-pole magnetic sheet, annular multi-pole magnetic sheet is installed more stable.This practicality also has that structure is simple, result of use good, can effectively reduce the electromagnetism field wave of motor, reduce motor radiation to features such as the infringements that human body causes.
