Power-saving motor

Energy-saving motor

This creation is about an energy-saving motor, especially an energy-saving motor that can output much greater than the rated output power in a short time.

In recent years, one of the worlds most watched issues is global warming. Global warming will cause sea levels to rise, low-altitude coastal areas will be submerged, and will have an impact on the ecological environment. Therefore, in order to reduce greenhouse gas emissions into the atmosphere to slow down the world With the speed of warming, energy saving and carbon reduction is an indispensable road, and saving energy can reduce energy consumption and leave more resources for future generations. In the history of human development, the agricultural era entered the light industry and then the heavy industry. Coming to the modern electronics industry, all are related to energy and power. Among them, the motor is one of the important power sources of industrial production machines. Electrical equipment that drives industrial production machines or other loads. A traditional motor is mainly composed of a stator and a rotor. The stator is stationary and generates an electromagnetic field to drive the rotor to rotate. The rotor is supported by a bearing to ensure that the rotor can use the bearing. It is the axis rotation. In the existing technology, if a load needs to input a certain amount of power, such as 50 horsepower, in order to operate normally, the user will connect a motor with the same rated output power as the input power of the load at the input end of the load, if it meets the CNS standard The specifications of a four-pole (50hp-4p) motor with a rated output power of fifty horsepower can provide sufficient input power for the load. However, the power required by the load under no-load is less than the power required under heavy load, but no matter how traditional motors are The energy consumed during heavy load or no load is equal, so traditional motors will waste energy when no load. The above are all unsatisfactory aspects of the existing technology, which need to be further reviewed and a feasible solution to be sought.

In view of the aforementioned shortcomings of the prior art, the purpose of this creation is to provide an energy-saving motor, especially an energy-saving motor that can output much greater than the rated output power in a short time, which can be provided to loads that need to input high power in a short time. Therefore, compared with traditional motors, it can reduce the energy consumed at no-load.

The main technical means adopted to achieve the aforementioned purpose is to make the aforementioned energy-saving motor include: a housing on which a plurality of vents are formed; a stator, which is arranged in the housing, and the stator is mainly composed of more than one piece of silicon steel sheet The silicon steel sheet is wound with a coil; a rotor is arranged in the stator, and one end of the rotor protrudes out of the casing; at least one cooling fan is arranged in the casing and is opposite to the rotor and the stator; Among them: the length of the silicon steel sheet that composes the stator is 1.2 to 1.25 times that of the conventional motor silicon steel sheet of the same rated output power, and the coil wire diameter is 1 to 1.5 times that of the traditional motor coil wire diameter of the same rated output power.

The energy-saving motor has a larger coil wire diameter than a conventional motor with the same rated output power, and can withstand the large current required when the input power is higher than the general input power to generate a larger output power. The time output is much higher than the rated output power, so the energy-saving motor can be provided with a lower rated output power than the rated output power of the traditional motor to the load that needs to input high power in a short time, such as injection molding machine, bottle blowing machine, punching machine, etc. Load use, when the load needs to input high power, the energy-saving motor will output a power greater than the rated output power of the energy-saving motor to provide enough energy for the load; and the cooling fan will blow the wind to the stator and rotor, The heat energy generated by components such as silicon steel sheets and coils that output power greater than the rated output power is taken away by air convection to reduce temperature rise, so that silicon steel sheets and coils will not deteriorate due to excessive temperature and increase resistance. Phenomenon reduces the output efficiency; after completing a short-term action to increase the output power, the energy-saving motor returns to the operating state when there is no load.

Since the rated output power of the energy-saving motor is lower than that of a conventional motor that can drive the same load, the energy-saving motor consumes less energy when it is empty than a conventional motor that can drive the same load, so it is better than conventional motors. Technology can effectively save energy.

The following figure illustrates the embodiment of this creation to illustrate the technical content of this creation in detail.

Please refer to Figure 1. This creation is mainly based on a housing 10 with stator 20, a rotor 30 and a cooling fan 40; wherein, the rotor 30 is rotatably arranged inside the housing 10, and the rotor One end of 30 passes through one side of the housing 10, and the cooling fan 40 is arranged on the other side of the housing 10; The partition 12, the number of the partition 12 can be one, more than one vent 14 is formed on the partition 12, and the partition 12 can separate the stator 20, the rotor 30 and the cooling fan 40; the bottom of the housing 10 The end is provided with a base 13 for stably placing the cylindrical shell 10 on a flat surface.

The stator 20 is mainly composed of more than one silicon steel sheet 21, and a coil 22 is wound on the silicon steel sheet 12. In this preferred embodiment, the energy-saving motor can be a four-pole or six-pole motor. The number of coils 22 wound on the sheet 12 is four or six.

The length of the aforementioned silicon steel sheet 21 that composes the stator 20 is 1.2 to 1.25 times the length of the conventional motor silicon steel sheet of the same rated output power, and the wire diameter of the aforementioned coil 22 is 1 time of the conventional motor coil diameter specification of the same rated output power To 1.5 times.

The rotor 30 includes a rotating shaft 31, two ends of the rotating shaft 31 are respectively pivoted on the partition 12 of the housing 10 and one side of the housing 10 and protrude from the housing 10; in this preferred embodiment The cooling fan 40 is arranged inside the other end of the casing 10.

If there is a load that needs to input high power for a short time, such as 50 horsepower, to operate normally, such as an injection machine, a bottle blowing machine, a punching machine, a shearing machine, a die-casting machine, etc., the user can connect to the input end of the load An energy-saving motor with a rated output power smaller than the input power of the load. In this embodiment, the energy-saving motor may be a four-pole (25hp-4p) motor with a rated output power of twenty-five horsepower. In other embodiments, The energy-saving motor can also be a two-pole (25hp-2p) motor with a rated output power of twenty-five horsepower. When the load needs to input a power greater than the rated output power of the energy-saving motor, the energy-saving motor will be The input power is greater than the input power when the energy-saving motor is fully loaded, because the length of the silicon steel sheet 21 in the energy-saving motor stator 20 is longer than that of the conventional silicon steel sheet of the same rated output power, and the wire diameter of the coil 22 is The conventional motor with the same rated output power has a thick wire diameter. The length of the silicon steel sheet 21 can increase the magnetic field generated by the stator, so that the energy-saving motor can output more power, and it can also increase the surface area of the silicon steel sheet 21 for heat dissipation. The wire diameter of the thickened coil 22 can increase the maximum current value that the coil 22 can withstand, and then increase the input voltage to reduce the increase in the input current. Therefore, the energy-saving motor can output much more than the rated output power in a short time ( (E.g. 25 horsepower) larger output power (e.g. fifty horsepower) to provide enough energy for the load; please refer to Figure 2, and the cooling fan 40 will inhale the air outside the housing 10 and generate air flow 50 Pass through the vent 14 on the partition plate 12 and blow towards the stator 20 and the rotor 30, and then the heat energy generated by the silicon steel sheet 21, the coil 22 and other components due to the output power greater than the rated output power is taken away by the airflow 50 to reduce the temperature rise , So that the components such as the silicon steel sheet 21 and the coil 22 will not reduce the output efficiency due to the deterioration of the resistance value caused by the excessive temperature; after completing a short-term action to increase the output power, the energy-saving motor will return to the no-load state The operating status.

Because the rated output power of the energy-saving motor is lower than that of a conventional motor that can drive the same load, in this preferred embodiment, the rated output power of the energy-saving motor that can drive a load of 50 horsepower is 25 horsepower, while the conventional motor The rated output power of the energy-saving motor is 50 horsepower, so the energy consumption of the energy-saving motor is lower than that of a conventional motor that can drive the same load when it is empty. In this preferred embodiment, the energy-saving motor consumes less energy when it is no-load. The energy of the traditional motor is half, so the energy-saving motor can effectively save energy compared with the existing technology.
