The G090-2290 asynchronous AC motor is an outstanding achievement under this concept, fully reflecting HEW's professional level and technical strength in the field of motor manufacturing.

2、 Analysis of Core Technical Parameters

Power and operating mode: The rated power of the motor is 1.1kW, and it operates in the S6-75% mode. This working mode means that the motor can operate continuously at 75% load under intermittent load conditions, making it suitable for industrial equipment such as cranes and elevators that require frequent start stop and periodic load changes. A power output of 1.1 kW can provide sufficient power support for various small to medium-sized industrial machinery, meeting the needs of different production processes.

Energy efficiency level and electrical parameters: The motor's energy efficiency level has reached IE3, making it an efficient and energy-saving product. In today's increasingly high energy costs, IE3 energy efficiency level motors can effectively reduce the energy consumption costs of enterprises and improve energy utilization efficiency. Its working voltage range is 220-240/380-420V, which can adapt to the voltage requirements of different regions and power supply systems. Through the D/S (delta/star) connection method, users can flexibly choose the wiring method according to the actual voltage situation. The frequency is 50Hz, which meets most industrial electricity standards. The thermal rating of the motor is F, which means that its insulation material can withstand high operating temperatures, ensuring the performance of the motor while improving its operational stability and service life.

Speed and protection performance: The synchronous speed of the motor is 1500U/min, which can provide stable speed output for the equipment, ensuring consistency and accuracy in the production process. In terms of protection, the motor has an IP54 protection level. This protection level enables it to effectively prevent dust from entering the interior of the motor, while also preventing water splashing from all directions from causing damage to the motor. It is suitable for harsh industrial production environments, such as textile workshops, mines, and other places where dust and water vapor exist.

Motor protection and structural design: Built in PTC (positive temperature coefficient thermistor) motor protection device. When the temperature of the motor winding is too high, the PTC resistance value increases sharply, thereby cutting off the circuit and protecting the motor from overheating damage, effectively extending the service life of the motor. The motor adopts the V3 installation form, which is suitable for applications where the motor shaft is vertically downward and has good stability. The flange outer diameter of the motor is 200mm, and the output shaft size is HEW standard WE 24 x 50, making it easy to connect and install with various mechanical equipment.

3、 Product features and advantages

UL certification and customized design: This motor has UL certification, indicating that it complies with the safety standards established by the Underwriters Laboratories (UL) in the United States. This certification provides strong support for the application of motors worldwide, especially in the North American market where safety standards are required. In addition, the motor is equipped with a UL specification fan (Ø 20) and uses 110LFe_KK sealing technology, as well as an additional explosion-proof junction box (Ex KB). These designs not only improve the safety of the motor in special environments, but also provide users with more customized choices to meet the special needs of different industries and working conditions.

Appearance and craftsmanship: The motor surface is coated with RAL 7031 color, which not only has a good visual effect, but also has certain anti-corrosion performance. The German manufacturing process ensures a dual quality of appearance and intrinsic performance for the motor. From the machining accuracy of components to the overall assembly quality, every link is strictly controlled to ensure the stability and reliability of the motor.

4、 Application scenarios

Industrial automation production line: In various types of industrial automation production lines, motors need to be frequently started and stopped and their speed precisely controlled. The S6-75% working mode and stable speed output of G090-2290 asynchronous AC motor enable it to efficiently drive conveyor belts, sorting equipment, robotic arms, etc., meeting the strict requirements of motor performance in automated production lines, and improving the operational efficiency and product quality of production lines.

Material handling equipment: For material handling equipment such as cranes, elevators, and electric hoists, the motor needs to have good overload capacity and frequent start stop performance. The 1.1kW power and S6-75% working mode of G090-2290 motor can provide sufficient power for these devices, ensuring the safe and efficient handling of materials.

Small processing machinery: In the field of small processing machinery, such as small lathes, drilling machines, milling machines, etc., the 1.1kW power of this motor can meet its power requirements. At the same time, the high efficiency and energy-saving characteristics of the motor, as well as its good protective performance, make these small processing machinery more stable and reliable during operation, reducing equipment maintenance costs.

Ventilation and air conditioning system: In ventilation and air conditioning systems, the motor needs to operate stably for a long time and has certain requirements for noise and vibration. The high efficiency, energy saving, and stable operation characteristics of G090-2290 motor can provide reliable power support for ventilation fans, air conditioning compressors, and other equipment. At the same time, its good protective performance can also adapt to the working environment of ventilation and air conditioning systems.
