Abstract

The utility model relates to an electronic DC motor without a commutator. The utility model is composed of a stator and a rotor, wherein, the rotor 1 is coaxially provided with a silicon collecting disks 2 and 3, an electricity controlling disks 6 and 7, and eight mutual insulating electricity controlling sheets 11 are uniformly distributed on each of the silicon collecting disks. The utility model uses the electronic mode to replace the mechanical fire striking reversing device, and the utility model has the characteristics of no spark generation, no high-frequency interference to the outside, capability of being made into high-voltage DC motor and less possibility of being damaged.

Description

Electronic dc motor

A kind of electronic type direct current machine that does not have commutator.

Direct current machine in the past all has commutator, during operation, constantly has the electricity orphan to produce on the commutator, thereby very easily burns commutator, needs often maintenance, and the normal use of giving direct current machine is for much bothering.

The purpose of this utility model is the design by a kind of new construction, removes the commutator in the direct current machine, thereby makes its arc control phenomenon, has the raising rotating speed, improves power, non-damageable characteristics.

Fig. 1 is an internal structure schematic diagram of the present utility model, and Fig. 2 is a fundamental diagram of the present utility model, and Fig. 3 is silicon gathering disk of the present utility model and control electroplax.Each label is respectively among the figure: 1 rotor, and 2 silicon gathering disks, 3 silicon gathering disks, 4 positive supplies brush, 5 negative supplies brush, 6 control electroplaxs, 7 control electroplaxs, 8 trigger brush, and 9 by brush, and 10,11 electric controlling pieces, 12 edge copper rings, 13 controllable silicons, 14 armature winding, D ₁-D ₈The winding termination, A ₁-A ₈Grid B ₁-B ₈Grid, 15 trigger brush.

The utility model is made up of stator and rotor, the coaxial silicon gathering disk 2 that is provided with on the rotor 1, silicon gathering disk 3, control electroplax 6 and control electroplax 7, uniform ring fills 8 controllable silicons on each silicon gathering disk, the outer shroud of silicon gathering disk is edge copper ring 12, be uniform-distribution with the electric controlling piece 11 of 8 mutual insulatings on the cylindrical of each control electroplax, trigger brush 8 and end brush 9 and be installed on the shell, join with

control electroplax

6 and 7 frictions of control electroplax respectively, positive supply brush 4 and negative supply brush 5 are installed on the shell, join with silicon gathering disk 2 and silicon gathering disk 3 frictions respectively, 16 controllable silicon terminations join with the armature rotor end respectively, 16 controllable silicon grids respectively with two control electroplaxs on electric controlling piece 11 join.

With the two poles of the earth DC motor is example, in conjunction with the accompanying drawings the 2 explanations course of work of the present utility model.Silicon gathering disk 2 connects positive source, and silicon gathering disk 3 connects power cathode.Work as power connection, when the controllable silicon grid does not have trigger current, do not have electric current to pass through in the armature rotor.Place A when triggering brush 8 ₄The place triggers brush 15 and places B ₈The place, and when adding trigger voltage simultaneously, electric current is then from D ₄The termination flows into, from D ₈Flow out the termination.Owing to have electric current to pass through in the armature, rotor 1 begins to rotate.Work as A ₃Contact B with triggering brush 8 ₇When contacting with triggering brush 15, electric current is from D ₃Flow into, from D ₇Flow out.By that analogy, have electric current to pass through in the armature continuously respectively, rotor just can rotate down continuously.When grid turns to triggering to brush 8, add 13 conductings of trigger voltage controllable silicon, when grid turns to when brushing 9, add cut-ff voltage, controllable silicon 13 ends.

The utility model has replaced mechanicalness sparking reversing arrangement in the electronics mode, has not produce spark, does not externally have High-frequency Interference, can be made into the high voltage direct current motor, and is not fragile, can improve characteristics such as rotating speed and power effectively, and promotional value is widely arranged.

Embodiment: with 100KW, 1000V, 2000 rev/mins, four utmost points, 32 grooves, can reverse no commutating pole DC motor is example,＜1〉in conjunction with the accompanying drawings, 2 and 3 diameters are 250mm, wide 30mm, and 8 and 15 diameters are 100mm, wide 10mm, 2 and 3 spacings are 10mm, and 3 and 8 spacings are 10mm, and 8 and 15 spacings are 5mm, controllable silicon volume stream is 15A, and volume is pressed and is 1500V.
