A domestic steel plant

Challenges

1) Large fans and water pump motors in operation suffer from issues related to prolonged usage and high energy consumption.

2) The degree of intelligence of the motor is low and cannot meet the needs of informationization and intelligence.

3) The maintenance workload for the inverter is significant, leading to substantial economic investments.

Implementation

Blowers are widely used in the steel mill, such as primary blowers, secondary blowers, etc., with high motor power and mostly high voltage. The high-power motor uses the frequency converter for frequency regulation, thereby achieving the effect of energy saving.

The high-voltage permanent magnet variable frequency speed regulation integrated motor realizes perfect coupling of high-voltage permanent magnet motor and high-voltage frequency converter. The original drive can be effectively replaced by personalized matching according to the original asynchronous motor, voltage, power, speed, center height, mounting feet, and other parameters. The drive system adds the control system with a display to improve the intelligence and digital transmission of the equipment as well as the miniaturization and convenience of the overall configuration.

Application effect

This solution adopts the permanent magnet variable frequency speed regulation integrated motor, which saves the construction investment of the electrical room of the frequency converter. The supporting intelligent controller completes the real-time uploading and protection of the maintenance data of the whole life cycle of the motor equipment operation information; the overall efficiency and the power factor of the permanent magnet integrated motor is significantly improved compared with the asynchronous drive system, and the overall power saving rate can reach more than 25% compared with the overall power saving rate, which reduces the investment of the operation cost, and is in line with our national policy of energy conservation and emission reduction.
