Energy feedback and regenerative braking: Siemens 6SE7035-1EJ84-1JC2 has built-in active front-end (AFE) rectifier unit, supports four-quadrant operation, and can feed back braking energy to the power grid. In mine hoist applications, the energy feedback efficiency reaches 95%, and the power consumption per ton of ore is reduced by 18%.

Multi-level inverter technology: Adopting NPC three-level topology, the output voltage waveform is close to sine wave, and the harmonic distortion rate (THD) is less than 3%, which significantly reduces motor heating and bearing loss. In the control of cement plant fans, the motor life is extended by 20% and the maintenance cost is reduced by 30%.

Field-oriented control (FOC): Siemens 6SE7035-1EJ84-1JC2 supports open-loop/closed-loop vector control, torque response time <50ms, in the control of the drying section of the paper machine, the speed tracking accuracy reaches ±0.1%, and tension closed-loop control is realized.

Water treatment system: Siemens 6SE7035-1EJ84-1JC2 is used for multi-pump parallel control of sewage lifting pump stations, and the number of running units is automatically adjusted through the load distribution algorithm. The sleep mode is activated during the low flow period at night, and the annual power saving reaches 450,000 kWh.

Metallurgical industry: In the dust removal fan system of the steel plant, multiple inverters are coordinated through the master-slave control strategy to achieve dynamic matching of air volume, and the power consumption per ton of steel is reduced by 12%. With the vibration monitoring function, the pipe wear caused by resonance is avoided, and the annual maintenance cost is reduced by 500,000 yuan.

Mining and transportation: Siemens 6SE7035-1EJ84-1JC2 drives underground belt conveyors, supports steep slope starting (maximum climbing angle 18°) and low-speed belt inspection functions, and avoids safety accidents caused by heavy-load shutdown. After deployment in a coal mine in Shanxi, the equipment failure rate dropped by 60%.

Ship power: Siemens 6SE7035-1EJ84-1JC2 is used for ship thruster control, supports -10°C low-temperature starting and salt spray anti-corrosion design, and realizes precise speed adjustment in ocean-going cargo ships, and the energy consumption is reduced by 28% compared with the DC motor system.
