Variable Frequency Drive of V&T Technologies


As we know, VFD drive play a major and very important role in nowadays. It can help the world life more comfortable and sustainable. Variable Frequency Drive for short can called VFD, other names can also called AC Drive, Frequency Inverter, Frequency Converter, adjustable speed drive, adjustable frequency drive, variable speed drive and microdrive. A VFD drive is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor.


Shenzhen V&T Technologies Co.,Ltd. Is specialized in low voltage variable speed drive and medium voltage frequency drive, pumping unit controller, servo drive and electric vehicle drive. The name of V&T means Vector and Torque control, it also express Victory and Trust. V&T has completely grasped the key control technique and also possesses the capacity of industrialization design and manufacturing. It has developed a lot of variable speed drive series. V&T self-develop variable frequency drives covering voltage level 200V, 400V, 690V, 1140V and power rating is from 0.4KW to 3000KW. Under the premise of meeting the demand for international standards and satisfying different industrial application, we further strengthened the product reliability and environmental adaptability to suit harsh and extreme environments. V&T variable frequency drive are widely used in metallurgy, crane, oil, chemicals, machine tools, electric vehicles, metal processing, building materials, stone, wood processing, ceramics, plastics, air compressor, washing machine, water supply, air conditioning, municipal engineering, textile, printing, mining and other industries.
