The transmit controller 91 may control the current, voltage and frequency passed to the transmit coil 8, which may control the magnetic field generated by the transmit coil 8 in space. The power supply access device is connected with the transmitting controller 91, on one hand, the power supply is supplied to the controller, on the other hand, the voltage current required by the transmitting coil 8 is provided, and the transmitting controller 91 modulates the frequency of the voltage current and then sends the modulated frequency into the transmitting coil 8.

The pulley 32 enables the long rod 21 to reciprocate in one direction, and friction can be greatly reduced because the contact surface of the long rod 21 with the pulley 32 is very small. The pulley 32 is very flexible in material, construction or arrangement, and generally has the primary purpose of reducing friction.
The magnetic field can magnetize the mechanical device in the magnetic field, the motion state of the mechanical device can be influenced by the changing electromagnetic field, for example, one end of the spring is fixed by adding the other end of the iron block, and then the changing magnetic field is applied, so the iron block can move, each mechanical device has inherent vibration frequency, the spring can generate larger stretching or contraction displacement near the inherent frequency, a larger displacement effect is generated by selecting appropriate parameters, the moving induction coil can cut the magnetic induction line to generate electric energy, the spring is always maintained on a very high resonance frequency by configuring the change rate of the magnetic field, so that higher induction current can be generated, and the effect of transmitting the electric energy is achieved.
