detailed description

 The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

 Example 1:

The field power generation and driving device shown in FIG. 1 includes a rotor 1 and a stator 2, and a magnet 3 and a power generating coil 4 are disposed on the rotor 1 and the stator 2, and the magnets 3 are alternately arranged single-pole magnets 5 and double magnetic poles. The magnet 6, the stationary single-pole magnet 5 and the double-pole magnet 6 each correspond to one power generating coil. The magnetization direction of the single magnetic pole magnet 5 is axial magnetization, and the magnetization direction of the double magnetic pole magnet 6 is tangential magnetization, that is, the N pole or the S pole face of the single magnetic pole magnet faces the power generating coil, and the N pole of the double magnetic pole magnet Together with the S pole, the generator coil is facing. The width of the magnet is the same as the width of the core. This structure is the most efficient.

 The power generating coil 4 is a three-phase power generating coil, and the three-phase power generating coil 4 is alternately arranged in each phase, and includes an A-phase power generating coil, a B-phase power generating coil, and a C-phase power generating coil, and the power generating coil in each phase power generating coil is positive and negative. The alternating series power supply coils mean that all the power generating coil power generating coils are connected in series in series, and the reverse series power generating coils mean that the heads and tails of two adjacent power generating coils are connected in series in series.

 The total number of magnets 3 is at least 12. The arrangement of the magnetic poles 3 is as shown in FIG.

 When the rotor moves relative to the stator, the magnetic field in the A-phase generating coil is still N pole, the B phase is changed from S pole to N pole, and the C phase is still S pole. Thus, the A-phase core induced magnetic field repels the N poles on the adjacent rotor poles, forming a two-way repulsive force that cancels each other out. The B phase changes to the N pole due to the S pole, and repels and attracts adjacent magnets to form a resistance to the rotation of the rotor. The C phase still maintains the S pole, attracting and repulsive forces to the rotor poles, and propelling the rotor to rotate. In this way, a partial offsetting attraction and repulsive force are generated between the ABC three-phase power generating coils, so that the resultant force for hindering the rotation of the rotor is small, which is the reason for the energy saving of the single- and double-pole magnet combined power generating devices.

 Example 2:

 The field power generation and driving device shown in FIG. 2 includes a rotor 1 and a stator 2, and a magnet 3 and a power generating coil 4 are disposed on the rotor 1 and the stator 2, and the magnets 3 are alternately arranged single-pole magnets 5 and double magnetic poles. The magnet 6, the stationary single-pole magnet 5 and the double-pole magnet 6 each correspond to one power generating coil.

The magnetization direction of the single magnetic pole magnet 5 is axial magnetization, and the magnetization direction of the double magnetic pole magnet 6 is tangential magnetization, that is, the N pole or S pole surface of the single magnetic pole magnet 5 faces the power generating coil, and the double pole magnet 6 The N pole and the S pole together face the power generating coil. The width of the magnet is the same as the width of the core. This structure is the most efficient. The power generating coil 4 is a single-phase power generating coil, and each of the two adjacent power generating coils constitutes one group. The two coils in the group are connected in series in the forward direction, and the adjacent groups are connected in series in reverse phase to output single-phase alternating current. The forward series power generating coil means that the heads and tails of the adjacent power generating coil power generating coils are sequentially connected in series, and the reverse series power generating coil means that the heads and tails of the adjacent two power generating coils are connected in series in series.

 The total number of magnets is at least 12. Its magnetic pole arrangement is shown as 2.

 When the rotor moves relative to the stator, the magnetic field in the No. 1 generating coil is still N pole, the No. 2 generating coil is changed from S pole to N pole, and the No. 3 power generating coil is still S pole. Such a generating coil induces a magnetic field that repels the N poles on the adjacent rotor poles, forming a two-way repulsive force that cancels each other out. The second power generating coil is changed to the N pole due to the S pole and the N pole, which repels and attracts adjacent magnets to form a resistance to the rotation of the rotor. The No. 3 generating coil still maintains the S pole, attracting and repulsing the rotor pole and propelling the rotor to rotate. In this way, the attraction and repulsive forces which partially cancel each other are generated between the three power generating coils, so that the resultant force which hinders the rotation of the rotor is small, which is the reason for the energy saving of the single and double magnetic pole combination power generating device.

 The field power generation and driving device shown in FIG. 3 includes a rotor 1 and a stator 2, and a magnet 3 and a power generating coil 4 are disposed on the rotor 1 and the stator 2, the magnet 3 is a double magnetic pole magnet 6, and the stationary double magnetic pole magnet 6 simultaneously corresponds. Two power generating coils.

 The magnetization direction of the double pole magnet 6 is tangential magnetization, and the N pole and the S pole of the double pole magnet collectively face the power generating coil.

 The power generating coil is a three-phase power generating coil, and the three-phase power generating coils are alternately arranged in each phase, and the power generating coils in each phase power generating coil are connected in series in the forward direction, and the forward series power generating coils refer to the head and tail of all the power generating coil power generating coils. Connect in series.

The number of magnets is six. Its magnetic pole arrangement is shown as 3, NS-NS-NS. When the rotor rotates clockwise with respect to the stator, the core of the C-phase power generating coil is changed from N to S, which partially cancels the attraction and repulsive force of the double-pole magnet, thereby saving energy.

Connect in series.

 The number of magnets is six. Its magnetic pole arrangement is shown as 3, NS-SN-NS-SN-NS-SN.

 When the rotor rotates clockwise with respect to the stator, the A-phase power generating coil core cancels the force of the double-pole magnets on both sides thereof, and the B-phase power generating coil core becomes S, which attracts the attractive force and repulsive force to the double-pole magnet. When the rotor rotates, the core of the C-phase power generating coil becomes N, which generates repulsive force and attractive force to the double magnetic pole, hinders the rotation of the rotor, thus generating a magnetic resistance that can be partially offset in the ABC three-phase power generating coil, thereby saving energy. effect.
