The invention provides a kind of high-efficiency energy-saving permanent magnet motor, this high-efficiency energy-saving permanent magnet motor is by its structural design, can be in running external mechanical work, simultaneously, also have the function of generating electric energy.
The rotor 4 that the high-efficiency energy-saving permanent magnet motor includes housing 1, central shaft 2, fixed coil 3 and with fixed coil 3 electromagnetism, coordinates, central shaft 2 is arranged on housing 1, fixed coil 3 is fixedly installed on central shaft 2, and rotor 4 is arranged on central shaft 2 rotationally.Housing 1 adopts metal material to make, and it has the effect that miscellaneous part is installed, and simultaneously, can also protect the parts that are installed in housing 1.Housing 1 has a cavity with installation effect, and central shaft 2, fixed coil 3 and rotor 4 all are arranged in cavity.Fixed coil 3 and the electrical connection of external electric energy storage device, externally under the power supply function of electrical energy storage device, fixed coil 3 can inspire magnetic field, this magnetic field and rotor 4 interact and can drive rotor 4 and rotate, rotor 4 is connected with exterior mechanical parts (for example power transmission shaft of automobile), externally outputting power.
Based on said structure, in order to make the high-efficiency energy-saving permanent magnet motor have the function of external output electric energy, in an embodiment of the invention, the high-efficiency energy-saving permanent magnet motor also comprises the power coil 5 that coordinates with rotor 4 electromagnetism, power coil 5 is sheathed on the outside of rotor 4, the electric wire that is connected with for external output current on power coil 5.
Rotor 4 consists of permanent magnet, and it can send magnetic field, and rotor 4 can rotate under the effect of fixed coil 3, thereby the magnetic field that it sends forms rotating magnetic field.Power coil 5 coordinates with rotor 4 electromagnetism, and the rotating magnetic field that power coil 5 forms in the time of can rotating rotor 4 is carried out the cutting of magnetic induction line, thereby generates induced current and by wire, externally export.
Need to prove at this, can generate induced field after fixed coil 3 energisings, for those skilled in the art as can be known: the parts that coordinate with coil electromagnetism (being rotor 4 in the present invention) are permanent magnet, with rotor 4(permanent magnet) electromagnetism coordinate for coil (power coil 5).
The present invention designs by said structure, on the basis due to the high-efficiency energy-saving permanent magnet motor that provides in the prior art, has increased especially power coil 5, and power coil 5 can cut the rotating magnetic field that forms in rotor 4 operation process, generates induced current.This induced current is externally exported by wire, and can again by motor, be utilized, thereby make externally mechanical work of high-efficiency energy-saving permanent magnet motor, simultaneously, can also generating electric energy.Design by said structure, high-efficiency energy-saving permanent magnet motor provided by the invention has spontaneous electrical function, has reached the purpose that improves its flying power under the prerequisite of rated power supply amount.
When high-efficiency energy-saving permanent magnet motor provided by the invention is installed on electric automobile, especially in the descending process, stop the power supply to the high-efficiency energy-saving permanent magnet motor, motor rotates with the driving shaft (automobile downhill relies on the gravity wheel to drive drive shaft turns) of automobile.At this moment, 4 runnings of the rotor of high-efficiency energy-saving permanent magnet motor, form rotating magnetic field, and can be fixed simultaneously coil 3 and power coil 5 of this rotating magnetic field cut generation two-way electric current.Therefore, must be electric energy with potential energy converting and energy when electric automobile is equipped with high-efficiency energy-saving permanent magnet motor provided by the invention, this electric energy is stored, and, by the electric automobile utilization, can improve dramatically the flying power of electric automobile.
