With the in-depth promotion of national energy conservation and emission reduction policies and the continuous increase in the demand for efficient use of energy, direct-drive permanent magnet synchronous motors have gradually entered the electric drive market. Especially in some coal mines and steel industries, the demand for synchronous motors has also increased day by day. Compared with asynchronous motors, synchronous motors have an absolute advantage in energy saving. It eliminates the need for bulky, high energy consumption and difficult-to-maintain gearbox components, which is favored by the transmission industry; and under the voltage level of 1140V, its current Significantly reduced, the heat generation (electrical loss) on the lines and copper bars has also been reduced, which not only saves a lot of space, but also saves costs for customers, and the market prospect is very broad. AC200 series inverter is a high-performance vector inverter newly developed by Wei Chuang Electric. This product adopts the international leading field-oriented vector control technology. It is not only compatible with asynchronous and synchronous motor control, but also supports speed, torque, and position. 3 control methods. While continuously improving product reliability and functionality, it has also made enhanced designs in terms of ease of use and professionalism. With its excellent control performance, reliable protection function, abundant interface resources, and super expansion ability, AC200 series inverters will become a model of a new generation of products recognized and trusted by customers. Brief introduction of AC200 technical characteristics: 1. Synchronous and asynchronous motor drives are integrated, with high-performance vector control with and without PG at the same time. 2. Accurate torque excitation decoupling, excellent dynamic performance, torque response time less than 10ms. 3. The low-frequency output effect is greatly improved, and the SVC can output 180% high starting torque at 0.50Hz. 4. The motor parameter learning ability is upgraded, and the full range of motor parameters can be accurately identified under static load conditions. 5. With the brand-new speed tracking function, the high-power motor can also realize the speed tracking start with zero waiting time and zero impulse current. 6. Support multiple communication protocols such as CANOPEN, MODBUS, and PROFIBUS. The figure below shows the AC200 performance test on the 1140v, 630kw permanent magnet direct drive synchronous towing unit, and the test load inverter is a 630kW explosion-proof inverter. Under 150% rated load, AC200 performs frequent start-stop control of the motor, the motor start-up process is stable, and the overshoot current is small. (Yellow is U-phase current, blue is V-phase current) It runs for a long time after heavy load starts, the current waveform is stable, the motor speed control accuracy is high, the low carrier frequency design makes the whole machine good heat dissipation, and the 120% rated speed over-speed operation ability, its control effect can well meet the mining belt Machine application requirements. The release of AC200 series inverters is another milestone in the product line of Flextronics's inverters. On the road of continuously pursuing to meet customer needs, Flextronics continues to improve its products and strive to become a pioneer in the development of localization and market internationalization in the inverter industry.
