Amid the growing trend of energy scarcity in the future, "green development" will be a crucial cornerstone for the sustainable progress of humanity. Meanwhile, with the rapid advancement of AI technology, intelligence will accompany humanity toward a broader future.

1. Motor part 1. The certification of the motor is: UL certification in the United States, CSA certification in Canada, and CE certification in the European Union.

The two greatest advantages of EC motors are:1. Intelligent control;1. EC motor can realize intelligent speed regulation and remote control according to the needs of practical application environment.

SEIE's EC motor and ECI motor are PMS permanent magnet synchronous motors designed on the basis of IEC standards, currently available in four rack sizes: IEC-71, IEC-80, IEC-90, IEC-100, IEC-112, IEC-132, with a maximum output power of 22kW and a maximum torque of 70Nm.

Canadian CSA certified motors are mainly sold to Canada or the United States of America, the recognition in Canada is relatively high, but in North America the United States recognition is not as good as UL certification authority. However, CSA certified motor products can be sold to Canada, the United States, North America and other countries, and the acceptance of a large range is an advantage of CSA certification compared to the situation.

IE5 energy efficiency motors are currently the highest motor efficiency standards issued by the International Electrotechnical Commission (IEC). SEIE and FINMEA motors are the first to launch IE5 energy-efficient permanent magnet ECI motors in China, which can help customers achieve energy saving, emission reduction and intelligent control of products, and some products have passed UL and ETL certification in the United States,

1) Phase loss operation: Any open circuit in one phase of a three-phase power supply will cause the motor to operate in a phase loss state. After a three-phase motor loses one phase of power supply, if it is in a stopped state, it will stall (unable to start) due to zero synthesized torque. The locked rotor current of the motor is much higher than the normal operating current. Therefore, in this situation, turning on the power for too long or repeatedly starting the power will cause the motor to burn out.

1. Idle speed: The speed at which the motor is normally powered on without load. (Unit: rpm or r/min or rpm/min) 2. No load current: The current at which the motor is normally energized without load. (Unit: mA milliampere or A ampere) 3. Load torque: The rated torque of the motor during load testing, for testing reference only. (Unit: g. cm or mNm)

Motor burnout is common in daily life, and the most effective preventive measure to avoid motor burnout is to carry out correct technical maintenance. The main maintenance methods include the following six points. Gao Tong will briefly introduce them as follows: 1. Regularly keep the motor clean. During operation, it is necessary to regularly keep the air inlet clean.
