Explosion-proof motors how to reduce energy consumption in the production, saving electricity, play a benefit? It should be considered from the following aspects.

Reasonable selection of motor type.YBX4 series motor is a series of products of national unified design, which is the advanced explosion-proof three-phase asynchronous motor in China at present, and its advantages are high efficiency, energy saving, and good starting performance. When purchasing a new motor, you should first consider choosing an energy-saving brand, and then consider other performance indexes as needed to save electricity.

Reasonable selection of the rated capacity of the motor. The state of explosion-proof motor three operating regions made the following provisions: load factor in 70% to 100% between the economic operation area; load factor in 40% to 70% between the general operation area; load factor in the 40% of the following non-economic operation area. If the motor capacity is selected too large, although it can ensure the normal operation of the equipment, but not only increases the investment, and its efficiency and power factor are also very low, resulting in a waste of power. Therefore, taking into account both to meet the needs of equipment operation, but also to make it as efficient as possible, the general load factor is maintained at 60% to 100% is more desirable.

Energy-saving transformation of old explosion-proof motors: (1) replacement of the motor's external fan, the motor's external fan into an energy-saving type, for different types of motors, there are corresponding energy-saving fan products available, mainly for single-direction operation of the 2-pole and 4-pole motors, after the change can be to improve the efficiency of 1.35% to 2.55%. (2) Adopt new insulating materials to increase the cross-sectional area of the wire. For the asphalt mica tape impregnated insulation of high-voltage motors, in the stator coil overhaul, epoxy glass powder mica tape insulation can be used to achieve the purpose of energy saving.

Frequency conversion speed regulation of electric motor. Adopt other continuous speed regulation operation mode, use voltage regulator governor, variable pole motor, electromagnetic coupling governor, frequency conversion speed regulation device, and so on.

Increase the voltage of the motor. When the asynchronous motor is lightly loaded, reducing its external supply voltage can realize energy saving.

Improve power factor. Paralleling an appropriate amount of capacitors at the outlet end of the asynchronous motor for reactive power compensation can improve the power factor, reduce reactive power loss, and effectively realize the saving of electric energy.
