Explosion-proof motor energy saving measures
2026-02-04
Explosion-proof motors in the production of how to reduce energy consumption, save electricity, play a benefit? 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 flame-proof three-phase asynchronous motor in China at present, with the advantages of 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. National explosion-proof motor three operating regions made the following provisions: load factor of 70% to 100% between the economic operation of the area; load factor of 40% to 70% between the general operation of the area; load factor of 40% below the non-economic operation of the area. If the motor capacity is selected too large, although it can ensure the normal operation of the equipment, but not only increased 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, the general load factor to maintain 60% to 100% is more desirable.
Energy-saving modification of old explosion-proof motors: (1) Replacement of the motor's external fan, the motor's external fan to energy-saving, for different types of motors, there are corresponding energy-saving fan products to choose from, mainly used for single-direction operation of the 2-pole and 4-pole motors, the efficiency of the change in the range 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.
Variable frequency speed regulation of electric motors. Other continuous speed regulation operation methods are used, using voltage regulators, variable-pole motors, electromagnetic-coupled speed controllers, and frequency conversion speed control devices.
Increase the voltage of the motor. Energy savings can be achieved by reducing the external supply voltage of an asynchronous motor when it is lightly loaded.
Improvement of power factor. Parallel connection of appropriate amount of capacitor for reactive power compensation at the outlet end of the asynchronous motor can improve power factor, reduce reactive power loss and effectively realise power saving.

Three-phase asynchronous motor starting mode
Frequency-sensitive resistance starting refers to the series connection of frequency-sensitive resistance in the main circuit when the motor starts, so as to reduce the starting current. Frequency sensitive resistance can smoothly change the starting current, the impact on the power grid is smaller, is more ideal starting method. However, high-power frequency sensitive resistors are used in the form of inductance, so in use will produce a large electromagnetic eddy current, which will reduce the power factor of the power grid.

What are the characteristics of permanent magnet direct drive motors?
Conventional motors rotate at high speeds and produce beeping sounds, and belts can become eccentric if used for too long. The permanent magnet direct drive motor can avoid these troubles and realize 1:1 transmission between equipment and motor, which makes the equipment compact, less noisy, more environmentally friendly and more professional. Direct drives are suitable for applications requiring low speeds, speed regulation and heavy loads. The main benefits of the improvement include quietness, energy saving, stability, strong power and intelligent transformation. So, the direct drive will bring you a better quality of life.

Short-time high overload permanent magnet synchronous motor electromagnetic heat research
With the development of all-electric technology, electric rudder is widely used in aerospace, military applications and other fields. The rudder system motor requires high power density, high dynamic response and high reliability. Permanent magnet synchronous motors are widely used in rudder servo systems because of their simple structure, high torque density, high power density and high efficiency.
