How does the motor save power? How to use the motor to effectively save electricity?

The electric motor is a device that converts electrical energy into kinetic energy, and high conversion efficiency can save electricity. Specifically, the iron and copper losses should be low. The stator made of inferior silicon steel sheet has poor insulation between the sheets, resulting in iron loss.

Look at the model bar of the motor from the nameplate, for example: Y132M 4 is a squirrel cage asynchronous motor, and YR132M 4 is a wound asynchronous motor.

1. Update and eliminate inefficient motors and high-power-consuming equipment: promote high-efficiency and energy-saving motors, rare earth permanent magnet motors, high-efficiency fans, pumps, compressors, high-efficiency transmission systems, etc. Upgrading and phasing out inefficient motors and high-power-consuming equipment; Adopt high-efficiency and energy-saving motors and system-related power-saving equipment and newly install motor systems.

Gradually restrict and prohibit the production, sale and use of backward and inefficient products. For the renovation of old equipment, the focus is on the modernization and transformation of small and medium-sized motors, fans and pump systems with high power consumption and the reasonable matching of constant flow systems.

2. Improve the efficiency of the motor system: promote advanced motor speed regulation technologies such as frequency conversion speed regulation and permanent magnet speed regulation, improve the adjustment mode of fan and pump motor systems, and gradually eliminate mechanical throttling adjustment methods such as rams and valves. Focus on the speed regulation transformation of large and medium-sized variable working condition motor systems, reasonably match the motor system, and eliminate the phenomenon of "big horse-drawn trolley".

3. Dragged device control and equipment transformation: the traditional mechanical transmission mode is transformed by advanced power electronics technology transmission mode, and AC speed regulation is gradually used to replace DC speed regulation. The use of high-tech transformation of the drag device, focusing on large-scale water conservancy and irrigation equipment, the total motor capacity of more than 100,000 kilowatts of large enterprises demonstration transformation, etc.

4. Optimize the operation and control of the motor system: promote soft start device, reactive power compensation device, computer automatic control system, etc., and reasonably allocate energy through process control to achieve economic operation of the system.

1. The newly purchased motor should first consider the selection of high-efficiency and energy-saving motors, and then consider other performance indicators as needed in order to save electric energy.

2. Improve the efficiency of the motor itself, such as changing the motor self-cooling fan to another cooling fan, which can stop using the cooling fan when the load is very small or the outdoor motor is in winter, which is conducive to reducing energy consumption.

3. Reconnect the stator winding into a star-delta hybrid series winding, and convert the star connection or triangle connection method according to the load weight, which is conducive to improving the magnetodynamic potential waveform generated by the winding and reducing the working current of the winding, so as to achieve the purpose of high efficiency and energy saving.

Fourth, the scattered section adopts other continuous land rushing speed regulation operation modes. Such as the use of voltage governor, pole change motor, electromagnetic coupling governor, frequency conversion speed regulation device, etc.

5. Replace the motor of the "big horse-drawn trolley", which is very easy to cause damage to the equipment in addition to wasting electric energy. In addition, reasonable adjustment of the motor supporting use can make the motor run in a high-efficiency working area to achieve the purpose of energy saving.

6. Reasonable installation of parallel low-voltage capacitors for reactive power compensation, effectively improving the power factor, reducing reactive power loss, and saving electric energy.

7. The cross-section of the wire leading to the electric energy meter and the motor from the joint should meet the current carrying capacity, and the wire should be shortened as much as possible to reduce the resistance of the wire and reduce the loss. These measures can be taken separately or in combination. In short, some necessary technical energy-saving measures should be taken for the fuel number motor, which is not only beneficial to the safe and stable operation of the power grid, but also enables users to reduce electricity expenses.

Ways to save power on the motor include:

The light-load step-down transport chain is not land-bound: For light-load motors, the shed can be operated in a step-down way to achieve energy saving.

Star angle switching: For the motor with heavy load, the star angle switching method can be used to save energy.

Staggered macro orange peak runs: Reducing the power of the motor for a short period of time to reduce electricity consumption, this method can be used without the need for continuous operation.

Intelligent control: Using intelligent control technology, the voltage and current of the motor are automatically adjusted according to the actual load of the motor to achieve the purpose of energy saving.

Use high-efficiency motors: Compared with traditional standard motors, high-efficiency motors can use energy more efficiently and reduce energy waste.

Dear, hello, I am glad to answer for you: permanent magnet motor made of permanent magnet saves electricity 1, DC motor, according to the structure, there are: series excitation DC motor, parallel excitation DC motor, compound excitation DC motor, permanent magnet DC motor, brushless DC motor, etc.

2. Among these DC motors, the permanent magnet DC motor is the most power-saving: there is no power consumption of the excitation winding. Brushless DC motors are also relatively power-efficient, but brushless conversion circuits consume power.

Hello dear, glad to answer for you! Industrial motors consume a lot of energy, accounting for 60% of the electricity consumption of the whole society, compared with ordinary motors, permanent magnet motors made of permanent magnets can save about 20% of electricity, and are known as "energy-saving artifacts" in the industry

The environment around the motor should be kept clean. 2.Check the power supply voltage and current changes with a meter.

Generally, the allowable voltage fluctuation of the motor is 5% of the rated voltage, and the allowable current unbalance value of each phase shall not exceed 10%.And pay attention to judge whether there is a lack of phase operation. 3.

Regularly check the temperature rise of the motor. Measure the temperature rise with a thermometer and not exceed the maximum permissible value. 4.

Monitor the bearing for common noise, seal well, and change the lubricating oil regularly. The oil change interval is 1000 hours for plain bearings and 5000 hours for rolling bearings. 5.

Pay attention to the sound, smell and vibration of the motor. During normal operation, the motor should sound evenly, without noise and special sound, and <>
