Description

Description Electromagnetic Rotor

Rotative system made up a transmitting shaft (10) supported m two ball-bearing fixed m a structure (13) with a disk m one of the extremities to support the moving coil (6), one pulley (12) in the other extremity to transmit the mechanic power through a driving-belt (11) , two graphite connection (8) (9), polymerised with metallic sediment with superior quality to polarization of the referred coil. Base structure (2) (3) for mechanic pillar of the different components, with rubber protection (1) to counterbalance mechanical vibrations. One pillar (4) to support the fixe coils (5) . Connecting cables (14) for polarization of the mentioned coils (5) .

Each coil (5) (6) is performed in a carriage with nucleus of cylindrical or rectangular (15) shape, air nucleus, and two lateral covers. The coil system(16) consists of two copper tapes, separated by a dielectric of macrofol, " an insulator tape". They are simultaneously rolled up m 397 spires where are connected, in upper extremity of one of the tapes a feed cable and m the lower extremity of the other tape another feed cable. Closed the coiled process is vulcanized with epoxide resin, which gives mechanical resistance, insulation and allows its utilization m high humidity level. After this phase, a paramagnetic ( 17) nucleus is inserted inside the coil where the upper side has a width equal to the general body and the other extremity is screwed down to allow its fixing. All this system is controlled by a module that allows the variation of the polarization, constructed with materials and components existing on the market and already attested. The conjugation of several potentialities and applications of these components allow it a believable and linear behaviour in the control of the referred system. The technical range of this system stands in the present electromagnetic spectre, nevertheless is different owing the coils not having a standard behaviour in relation to the power consumption, they have not internal resistance, placing several questions of theoretical quality: According to the ohm's formula R=V/ I. With R=O and having a tension V on the coil, appear us the first theoretical difficulty to solve this equation, impossibility or irresolution. According to the Joule's formula w=I²xR, appears the same impossibility. According to Weber's formula Um= ψxRm we see that the magnetic tension (Um) is the result of the multiplication of phi (φ) by the reluctance (Rm) . We go on with the same impossibility. According to Lenz's formula Δ(cosψ)/Δt we obtain that the induced electro-motive power (Ei) is the result of the division of the rate of the cosine of phi (Δcosφ) by time variation. As cosine of phi is equal to zero, the irresolution is maintained. In practice submitted to several measures and tests we obtained a residual power consumption of 6 mA resulting more from cable feed then coil power consumption. The value of phi (ψ) stands unaltered and equal to zero. Practical situation without theoretical justification known.

The system, owing to the fact of producing mechanical energy, apply to all the mechanisms that need it, namely collecting water, water pumps, apply also to raising systems, centrifugal engines and pumps, etc.
