GE 369-HI-R-M-0-0-0-E electric machinery
Due to the large starting torque of some load characteristics and the difficult starting equipment, 369HIRM000E, such as extruder, washer, dryer, mixer, coating machine, mixer, large fan, water pump, roots blower, etc. can be started smoothly. This is more effective than raising the starting frequency. 369-HI-R-M-0-0-E uses this method in combination with the measures of changing from heavy load to light load to improve the current protection value, and almost all equipment can be started. Therefore, it is the most effective and convenient way to increase the starting torque by reducing the base frequency.
When this condition is applied, the base frequency reduction does not have to be reduced to 30Hz. The frequency of 369HIRM000E can be reduced gradually every 5Hz, as long as the system can be started.
The lower limit of base frequency shall not be lower than 30Hz. In terms of torque, the lower the lower limit, the greater the torque. 369-HI-R-M-0-0-E But it should also be considered that the IGBT will be damaged when the voltage rises too fast and the dynamic du/dt is too large. The actual use result is that when the frequency of 50 Hz drops to 30 Hz, this measure of raising torque can be safely and safely used.
Some people worry that the voltage of 369HIRM000E has reached 380V when the base frequency is reduced to 30Hz. So when the normal operation may need to reach 50 Hz, whether the output voltage jumps to 380 V, so that the motor can’t stand it? The answer is that this phenomenon will not happen.
At the beginning of the “Fourteenth Five-Year Plan” in 2021, the comprehensive implementation of 369-HI-R-M-0-0-H-E China’s digital transformation has entered the key “inflection point” stage. At the same time, under the requirements of the “3060 carbon target”, the transformation and upgrading of Chinese manufacturing enterprises is imminent. However, in terms of specific applications, the digital integration of 369-HI-R-M-0-0-H-E IT and OT is still a “mountain” in front of the transformation of manufacturing enterprises, and the data value is difficult to fully play.
With a history of 118 years, Rockwell Automation, as an enterprise in the field of global industrial automation, 369-HI-R-M-0-0-H-E informatization and digital transformation, has deeply rooted in the pain points of industrial demand, and is facing users in the Chinese market. Rockwell Automation China officially launched the “future, Rockwell Automation digital integration journey” – AUTOMATION FAIR ® AT HOME helps Chinese manufacturing enterprises cope with the challenges of digital transformation, intelligent manufacturing and carbon emissions, and 369-HI-R-M-0-0-H-E efficiently steps into the digital path of low-carbon energy conservation.
Actually speaking of the AUTOMATION FAIR of Rockwell Automation ®， Many users in the field of automation are familiar. As a very forward-looking international exchange activity, the annual AUTOMATION FAIR ® All are ready to receive the attention of the industry.
Good news, this year Rockwell Automation will ® Upgrade to AUTOMATION FAIR ® AT HOME has carried out a new concept and design, adhering to the concept of safety, high participation and strong information, enabling more technologies to enable the digital transformation of Chinese manufacturing enterprises, ETT-VGA UNIOP intelligent manufacturing and carbon neutral landing, and bringing new experience to participating users.
