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.

1： A 2-pole motor with conventional number of poles and speed. Rotational speed 2950 rpm 4-pole motor. A 6-pole motor with a speed of 1470 rpm. An 8-pole motor with a speed of 750 rpm. Speed 500 rpm: 1. The number of stages of the motor actually reflects the synchronous speed of the motor. For example, for a motor with stages 2, the synchronous speed is 2900rpm, for a motor with stages 4 it is 1450rpm, for a motor with stages 6 it is 1000rpm, and for a motor with stages 8 it is 750rpm.

The widely used sewage treatment processes currently include oxidation ditch process and SBR process, among which oxidation ditch process is the most common. With the increasing demand for aeration equipment in the oxidation ditch treatment process and the increasing shortage of energy

Gear transmission has a wide range of applications in various machinery. It has many advantages compared to belt drive, chain drive, worm gear and worm gear drive, etc. For example: wide speed range of transmission, transmitted power

Dampness is a fatal factor leading to motor failure, as splashing rainwater or moisture generated by condensation can invade the motor. Especially when the motor is in intermittent operation and has been parked for several months, the coil insulation should be checked before use, otherwise it is very likely to be damaged
