Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of commutator movement.
Background technology
Commutator is commonly called as commutator, is parts in order to motor can be allowed to continue to rotate down on DC permanent magnet series-wound motor.Commutator comprises: mechanical commutator, partly mould commutator, all-plastic commutator.The commutator that automobile starter adopts mainly uses mechanical arch commutator, plastic commutator.Structurally, it is round that commutator is that several contact chip surrounds, and connects epitrochanterian each contact respectively, and two electrodes that outside connects are called that brush contacts with it, simultaneously only contact wherein two.
Its operation principle is: when coil is by after electric current, can under the effect of permanent magnet, by attracting and repulsive force rotation, when it forward to balance with magnet time, originally the contact led on the more corresponding commutator of line of electricity is just separated with brush, and brush is connected to meet and produces on the contact corresponding to that group coil of motive force, so ceaselessly repeat down, DC motor has just been turned over.If do not have the effect of commutator, that motor can only turn just stuck less than half-turn, can only be used as electric brake.The centrifugal force produced when utilizing motor to rotate, as power, controls the size of starting resistance, reaches and reduces motor starting currents, increase starting torque, make Wound-rotor asynchronous electric thought realize the device of brushless automatic control operation.
Brshless DC motor generally comprises rotor and stator, and the rotor of motor, for realizing the conversion of electric energy and mechanical energy, is generally provided with iron core.The rotor core of rotor be generally silicon iron sheet through mould punching, be overrided to form, existing iron core silicon iron sheet installs inconvenience, and in running, radiating effect is poor simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of commutator movement.
The utility model is achieved through the following technical solutions:
A kind of commutator movement, comprise the silicon iron sheet of rotating shaft, commutator and Multi-stacking compaction, described commutator is arranged in rotating shaft, described silicon iron sheet be circumferentially provided with several coil mounting grooves, described rotating shaft is provided with radiator fan, described rotating shaft is provided with the first mounting panel, the second mounting panel that are arranged symmetrically with, circumferentially some connecting axles between described first mounting panel, the second mounting panel, described silicon iron sheet is arranged between the first mounting panel, the second mounting panel, and the side of described first mounting panel, the second mounting panel is provided with some blocks of heating panels.
