Description

Electric motor capable of generating electricity at the same time

technical field

The utility model enables the electric motor to have the function of generating electricity at the same time.

Background technique

Generally, the general structure of the existing electric motor is: it is composed of a stator, a rotor, and a casing. The stator has a silicon steel body that is wound with an electromotive force coil. The rotor has a combined magnet and a rotating shaft. When the electromotive force coil is energized, a magneto-electromotive force with N and S pole changes can be generated, which acts on the magnet of the rotor (also has N and S poles), and the magnet can be rotated, that is, the assembled shaft can be rotated. It can be seen from the above that the existing electric motors only have the function of simply "energizing and rotating the shaft", and do not have the function of "simultaneously generating and outputting power". To obtain constant speed and speed regulation of the rotating speed, another generator is required to generate electricity for the speed regulation controller, and the speed regulation controller can obtain a stable power supply.

Utility model content

In order to improve the shortcomings of the prior art, the utility model provides an electric motor capable of generating electricity at the same time, which is characterized in that: the electric motor capable of generating electricity simultaneously includes a stator, a rotor, and a casing, and the silicon steel body of the stator Not only is the electromotive force line wound around, but also the generator coil is wound around it. When the electromotive force coil is energized to generate electromotive force to rotate the magnet shaft of the rotor, the magnetic force line of the rotating magnet acts on the generator coil, so that the generator coil can generate alternating current. The effect is that when the electric motor rotates, another alternating current output can be generated for other purposes.

The main technology and purpose are: the silicon steel body of the stator of the electric motor is not only provided with the electromotive force line for driving rotation, but also provided with a generator coil. When the motor shaft rotates, the magnet that is the rotor also rotates. Therefore, the rotating magnet The magnetic force can act on the generator coil, so that the generator coil can generate alternating current, and the output power can be used as power supply for other purposes.

Detailed ways

Please refer to Figures 1, 2, and 3, which include: a stator 10, a rotor 20, and a housing 24. The stator 10 is provided with a silicon steel body 11 that is wound with electromotive force coils 12 arranged according to settings. The rotor 20 has a combined magnet 22 and an assembly plate. 21. The magnet 22 of the rotor 20 corresponds to the silicon steel body 11 of the stator 10; the characteristic is that a group of generating coils 13 are wound around the silicon steel body 11 of the stator 10, and the generating coils 13 are connected with power output lines 130.

The electromotive force coil 12 of the utility model is connected with a power supply input line 120, and can be used for plugging in an external power supply.

When the electromotive force coil 12 and its power supply input line 120 input power (energized), the electromotive force coil 12 and the silicon steel body 11 can generate a magneto-electromotive force, and must interact with the magnet 22 of the rotor 20 to form the effect of making the magnet 22 rotate. Rotating the integrated rotating shaft 23 is the rotating action of the motor, and the rotating shaft 23 is connected to drive the object to be actuated. Moreover, when the magnet 22 of the rotor 20 rotates, the magnetic force lines of the magnet 22 can act on the generator coil 13. In other words, the generator coil 13 of the stator 10 can cut the magnetic force lines of the magnet 22, so that the generator coil 13 can generate alternating current. , that is, the AC power can be output from its power output line 130 .

The magnitude of the alternating current generated by the above generating coil 13 depends on the specifications of the motor. Take a motor with a "rotating speed of 3000rpm" as an example: after actual testing, an alternating current of 10V is obtained, while at a "rotating speed of 2000rpm", it is 6.7V.

It can be seen from the above description that the utility model can make the "electric motor" have the function of "power generation" at the same time, therefore, the obtained low-voltage alternating current can be used for other equipment that needs low-voltage power supply, for example: it can be used as lighting for lighting equipment , It can also be rectified to be "direct current" as the power supply for the speed controller. (Note: The speed controller adopts low-voltage direct current). In other words, the utility model enables the motor not only to drive other objects, but also to be a "generator", achieving excellent practicability and enhanced efficacy.

In addition, the above-mentioned technical means and ideas can also be implemented in this utility model as shown in Figure 4, which is: the stator 10 can be assembled with two sets of generating coils 13, and of course three or four sets can also be assembled, depending on the needs the set quantity.
