Brush 24,25 is contacted in horizontal opposition shape with the arc surface radial friction.In conjunction with Fig. 1, to reach timing, setting electromagnet 13,
15 in upper and lower dead-centre position commutator segment 22,23 beginnings contacted with second pair of brush 24,25.Electromagnet 13,15 after power-off exists
Its stroke middle position is stress balance point, and iron core becomes ferrimagnet by 11,14,16 size phase of both ends permanent magnet
Deng, two contrary attractions, but when electromagnet 13,15 is run among its stroke from upper (lower) stop energization stress
Powered off when position, move generation inertial force can make electromagnet 13,15 cross equalization point continue downwards (on) stop direction
It is mobile, then under (on) attraction at the increasing and upper (lower) stop end of attraction at stop end is smaller and smaller, electromagnet
13,15 will reach down (on) stop, then the power-off of electromagnet 13,15 point can be determined in the case where its stroke middle position is arrived
(on) between stop, the vortex and magnetic hystersis loss that electromagnet 13,15 generates when to reduce the commutation of electric current moment, then as far as possible
Extend the interval time that is powered twice of electromagnet 13,15, electromagnet 13,15 is just set and powers off point in its stroke middle position, in
It is that the setting end that commutator segment 22,23 is contacted with second pair of brush 24,25 at its stroke middle position of electromagnet 13,15 is de-
From contact, 13,15 1 stroke crankshafts of electromagnet rotate 180 °, then 1/2 stroke crankshaft rotation of electromagnet 13,15
90 °, two commutator segments 22,23 are then just set in Fig. 2 circle corresponding with the range that second pair of brush 24,25 is connected
Heart angle is 90 °, i.e. the switching stroke of two commutator segments 22,23 and second pair of brush 24,25 respectively accounts for the 1/4 of circumference, is used for
It controls 2 primary current direction of alternation weekly and electromagnet is made to originate 1/2 stroke and be powered, in addition 1/2 stroke powers off.
Two two collector rings 18,19 corresponding with Fig. 1 of commutator segment 22,23 connection in Fig. 2, electromagnet 13,15 and the

Formula connection, another pair brush are connect with DC power supply.
Since homopolarity is oppositely arranged permanent magnet 11,14,16 in order, work as N+When > 1,13,15 pairs of two neighboring electromagnet
11,14,16 magnetic pole of permanent magnet answered is different, to keep two neighboring electromagnet 13, the direction of 15 stress identical, is just arranged adjacent
Two electromagnet 13, the magnetic pole of 15 same positions are different, and the electricity of two adjacent electromagnet 13,15 armature winding is then arranged
Flow two contrary, i.e., adjacent electromagnet 13,15 wiring directions difference.
Permanent magnet 11,14,16 and electromagnet 13,15 are arranged between two slides 10 and 17.
Permeability magnetic material can be magnetized attraction, due to telescopic shaft 12 in 11,14,16 through-hole of permanent magnet reciprocal telescopic
Movement makes its stretching motion by resistance to prevent magnetic field from attracting telescopic shaft 12, therefore telescopic shaft 12 uses non-magnetic material
Material.
DC power supply exports alternating current supply electromagnet 13,15, therefore electromagnet 13,15 after electric current interval commutator 9
Magnetic pole checker；Due to DC electromagnet is thin and grow, iron core active area is small, coil impedance is big, starting is slow, access friendship
It can not be worked after time-dependent current by the electric current very little of coil；The characteristics of alternating electromagnet is short and thick, iron core active area phase
To big, coil induction reactance is big, impedance is small, and starting is fast, since its iron core uses the silicon steel sheet of mutually insulated, can effectively reduce friendship
The eddy-current loss and magnetic hystersis loss that time-dependent current lower electromagnet generates, it is alternating electromagnet that electromagnet 13,15, which is then arranged,.Due to
There are a voltage over zero, i.e., flashy power-off when alternating current, alternating electromagnet has short-circuited conducting sleeve, and effect is continuous magnetic, this
Electromagnet 13, about 15 each half stroke distances are set in utility model in power-off loss of excitation state, there is no need to continuous magnetic, therefore
It is not provided with short-circuited conducting sleeve.
For the frictional force for reducing telescopic shaft 12 and two slides 10 and 17, it is straight line that two slides 10 and 17, which are then arranged,
Bearing.
The brush 20,21,24,25 is arranged in brush carrier, and brush carrier insulation is fixed on the sky of the corresponding position of rack 1
Between on.
DC power supply (1-3 phase alternating current or battery feed after rectified) after corresponding control unit by distinguishing
The alternating current for exporting weekly 2 primary current direction of intermittent alternative supplies the electromagnet of corresponding set of magnetic drive unit.Below according to
Attached drawing illustrates the course of work of the utility model by taking one group of magnetic drive unit as an example:
The Starting mode of the utility model is similar with internal combustion engine, connects DC power supply, while applying to 2 direction of rotation of crankshaft
The torque for adding a rotation, when electromagnet 13,15 reaches top dead center position, commutator segment 22,23 and second pair of brush 24,25 are logical
Road, electromagnet 13,15 work, and top dead centre end generates identical with the permanent magnet at top dead centre end magnetic pole, lower dead center end generate and
The opposite magnetic pole of the permanent magnet at lower dead center end, due between magnetic field homopolarity repel, heteropolar attraction, then electromagnet 13,15 both ends magnetic
Pole is simultaneously by identical two active forces in direction i.e. by the repulsive force at top dead centre end and the attraction at lower dead center end, then
Electromagnet 13,15 pushes telescopic shaft 12 mobile to lower dead center direction rapidly and makes 5 energy storage of flywheel, reaches its stroke middle position
When, telescopic shaft 12 pushes connecting rod 4, crank throw 3 that crankshaft 2 is made to have rotated 90 °, at this time commutator segment 22,23 and second pair of brush 24,25
Open circuit, electromagnet 13,15 power off, and iron core becomes ferrimagnet and simultaneously the permanent magnet side by both ends after losing magnetism
To opposite, equal-sized two attractions, but due to the inertia force effect that flywheel 5 stores, cause the stress at its iron core both ends
Disequilibrium, it is mobile in being to continue with downward stop direction, with continuous separate top dead centre and close to lower dead center, top dead centre direction
Permanent magnet field it is just smaller and smaller to the attraction of iron core, and the permanent magnet field in lower dead center direction is to the attraction of iron core
It is increasing, lower dead center is then reached, crankshaft 2 has rotated 180 ° at this time；At this time commutator segment 23,22 and second pair of brush 24,
25 commutation accesses, the opposite electric current of outbound course supply electromagnet 13,15, and then electromagnet 13,15 pole orientations change,
Lower dead center end generates magnetic pole identical with the permanent magnet at lower dead center end, and top dead centre end generates the permanent magnetism iron phase with its top dead centre end
Anti- magnetic pole, similarly, electromagnet 13,15 reach top dead centre, and crankshaft has rotated 360 ° at this time, and and so on, power is by crankshaft 2
End output.
