Description

The invention relates to the field of electrical machines, in particular to electric DC machines.

Closest in design, it approaches unipolar machines with permanent magnet excitation.

These machines, along with the advantages, have some disadvantages. For example, the presence in their design of nodes with sliding brush contacts in an electrical circuit. Another disadvantage is that they, as a rule, are only low-voltage.

The technical result of the claimed invention is the rejection of nodes with sliding brush contacts and a significant increase in the output operating voltage of the machines.

The technical result is achieved by the fact that in the claimed design of a high-voltage non-contact unipolar electric direct current machine (VBUEMPT) there is a double non-contact movable inductor with permanent magnets and a fixed armature with a multi-turn winding, in which the active wires are connected in series.

The proposed high-voltage non-contact unipolar electric DC machine, consisting of a movable double inductor with a common vertical drive shaft and common upper and lower stationary ferromagnetic disks, one of which is mounted with two bearings on the right vertical, tubular, fixed axis, the other on the left of the same axis , in the same order, the lines of induction of their common magnetic field which are closed through common, called ferromagnetic fixed magnetic circuits, tightly adjacent dielectric and non-magnetic materials to their vertical tubular axes, and from a common fixed armature with a flat dielectric disk laid on its upper surface parallel to the active wires of the turns of its winding, characterized in that the double inductor is made as two integral, each of which has two disks of permanent magnets with holes in the middle for bearings and polarities opposite to the poles of two other disks, external the edges of which are frictionally connected with the common shaft, and parallel, active wires of the armature connected in series, intersect the entire width of its disk, between the opposite magnetic poles of the halves of both integral inductors, the beams of which are passed through the upper halves of both transitions and at the end their fixed tubular axes, and together with the return wires are formed in the turns of the armature winding and its ends are brought to the electrical terminals of the machine.

In figures 1 and 2 shows the transverse and horizontal sections of the proposed VBUEMPT.

The following notation is used in the figures:

1-1 'Upper and lower locking ferromagnetic fixed disks.

2-2 'Upper and lower disc-shaped permanent magnets of the left inductor.

3 - Active wires of turns of a winding of a fixed armature.

5 - Flat dielectric fixed disk of the anchor.

6 - A bunch of return wires of the turns of the armature winding.

7-7 'Right and left vertical, tubular, fixed axes of disc-shaped permanent magnets of the entire movable inductor.

8-8 'Upper and lower friction lining of the extreme surfaces of the disk-shaped permanent magnets of the left inductor.

9 - Driven gear pulley of a common vertical shaft.

10-10 'Upper and lower disc-shaped permanent magnets of the right inductor.

11-11 'The upper and lower friction pads of the extreme surfaces of the disk-shaped permanent magnets of the right inductor.

12-12 'Upper and lower dielectric and non-magnetic materials.

In figure 1, the active wires of 4 turns of the armature winding are shown slightly above each other for clarity, although they lie on the same plane of the dielectric disk of the armature 5. The direction of flow of the induction currents of the armature winding, the direction of rotation of the inductor disks with permanent magnets 2-2 ', 10-10 'and the drive shaft 3 are shown at a time when the machine is in generator mode.

VBUEMPT in generator mode work as follows. When the common shaft 3 is rotated through the driven pulley 9 by an external motor, the disk-shaped permanent magnets of two integral inductors begin to rotate with friction pads 8-8 'and 10-10' clockwise relative to the active parallel wires 4 of the anchor winding. At their ends, they are induced (induced) by electromotive forces (EMF) e _{and of} one direction, which in the turns of the armature winding will cause induction currents i, the directions of which are shown in figures 1 and 2. These currents will flow if you connect some electrical terminals to the machine any load. And without them, at the same time, only the constant voltage U _and , as shown in FIG. 1.

In the case when connected to the named terminals VBUEMPT, constant voltage U _and it will work in motor mode. At the same time, currents flow through the armature turns, respectively, along the active wires, with which the magnetic fields immediately emanate from the permanent magnets 2-2 'and 10-10' of the double inductor and they begin to rotate in the direction determined by the rule of the left hand . At this time, will begin to rotate and the common drive shaft 3 is frictionally associated with them. The driven gear pulley 9 mounted on it will also begin to rotate, to which some mechanism can be attached.
